Welcome to a new series that I’m calling “BitB Bits,” an irregular collection of random natural history observations recorded in my notes over the previous month. The individual snippets are, by themselves, too short for stand-alone posts, but I hope that readers will find their collective and chronological nature interesting and informative.
March 9. Welcome home walk. Good to be home and glad to see we didn’t miss the start of spring here. Non-native daffodils are blooming everywhere (I must admit they make an impressive display); however, we also have our first native blooming plant—spicebush (Lindera benzoin). Apparently only the male plants are blooming so far (distinguished by their flowers with stamens/anthers only but lacking a central pistil); the female plants should follow suit shortly.

March 12. Spring on hold. Now that spicebush is in bloom, a succession of flowering trees and shrubs should follow. Fragrant sumac (Rhus aromatica) would be the next to follow, but the rain of the last few days has put it on hold. The buds are swollen and ready, however, to burst forth on the next sunny day.

March 13. In my happy place. I didn’t get enough hiking at St. Francois State Park to satisfy my desires, so on the way back home I decided to stop off at Victoria Glades, one of my favorite places, and walk the perimeter of the main glade. I don’t think there’s another place on earth where I feel more connected to myself as a naturalist than here. I first visited way back in 1983 – the year after I moved to St. Louis after finishing grad school, and every year for the next eight years I came here once or twice per week throughout the summer to collect insects. I essentially “grew up“ here as an entomologist! In the time since moving back to St. Louis (now 27 years ago), I have resumed my regular visits – more in some years, less in others, and each time I do I feel rejuvenated. I have instructed Madam to sprinkle my ashes here (at least some of them) – if I depart and you happen to read this, please follow up with her to make sure that she does just that!

March 15. Beware the Ides of March. On this day, in 44 B.C., Julius Caesar was stabbed to death by a mob of Roman senators led by his friend Brutus. The senators believed that Julius had consolidated too much power (he had only a year earlier been named dictator for life and was implementing sweeping imperialist offensives in an effort to expand Roman territory), and that his death would lead to the restoration of the Republic. Sadly (or fortunately, depending upon your perspective), the “Ides of March” plunged Rome into centuries of civil war that ultimately led to utter collapse by the 5th century. In the final years of the empire, a series of emperors took the throne in quick succession (usually after the murder of their predecessor by the Praetorian Guard, the emperor’s personal bodyguards), each of whom plundered the state while they had the opportunity. The Roman Senate, engaged in their own corrupt practices and suffering from incompetence, was unable to curb the excesses of these emperors, leading to a waning of civic pride and loss of trust by the Roman citizenry before the final collapse.
March 17. C-c-cold! Once again, the bright sunshine was deceptive, belying how cold it really was – especially with that wind! Temps plummeted even further once the sun set, but the views around my home are still spectacular.
“The pond” on Pond Rd
March 21. Still waiting… …for native blooms to begin. Until then, here is yet another non-native early bloomer—Scilla forbesii (Forbes’ glory-of-the-snow), which invaded the woods near my home after a neighbor planted some in their woodland garden. They are not nearly the problem that some other invasives are (like bush honeysuckle or burning bush) in that they don’t smother out nearby native plants, but they can provide a pollinating “sink” that competes for insects that would otherwise be pollinating the flowers of native plants.
Scilla forbesii (Forbes’ glory-of-the-snow)
March 22. Vernal equiNOT. Spring began two days ago, yet I’m still waiting for the first appearance of any native wildflowers in the neighborhood. Until that happens, here is yet another non-native species—the thankfully noninvasive hyacinth—that my neighbor planted in their garden.
Hyacinthus sp. (hyacinth)
March 24. Spring at last, spring at last, thank God Almighty, spring at last! Finally, after sitting dormant for more than a week, the flowers of Rhus aromatica (fragrant sumac) have opened—in my opinion the true opening salvo of spring. Even so, it’s not like the weather suddenly turned spring-like, but more like the sumacs finally said F this and decided to open despite the continued dreary conditions.

March 25. How do snail’s eyes differ from slug’s? They don’t—they’re both eye tentacles. 🥁

March 26. Spring beauty. Now that spring is truly here, Claytonia virrginica (spring beauty)—the icon of spring ephemeral wildflowers—has begun popping up everywhere.

March 26. Water spider. I saw this large fly sitting on the curb. Of course, I knew it was a crane fly—a member of the family Tipulidae, but I hear people often confuse them for a “giant mosquito.” There is no such thing, and while I admit that they do look superficially like a mosquito on steroids (they happen to be distantly related to mosquitos), they do not bite or suck blood—arguably the most important part about being a mosquito. In fact, crane flies often do not eat anything once they become adults, with some species even lacking functional mouthparts. The family name is derived from the Latin word for “water spider,” perhaps because the larvae live in water and have a ring of tentacles around their head—just guessing. Anyway, I snapped a few pics of the little guy before he feebly began flapping his wings in the chilly air and took flight, probably looking for something to not eat.
Tipula sp. (crane fly)
March 28. Back to winter (midge). A few tantalizingly warm, sunny days had my hopes up that spring was finally here, but the return of cool, wet conditions have brought back that late winter feel. Perhaps appropriately, one of the first insects I’ve seen this season is this small, mosquito-looking fly that is actually a distant relative belonging to a group known as winter midges (genus Diamesa—also called snow midges—in the family Chironomidae). As their common names imply, the adult flies are seen active primarily during winter and can even be seen walking about on snow during warm spells during the winter (a scenario mimicked by the styrofoam on which this individual was photographed). Like the crane flies that I featured a couple days ago, winter midges do not feed as adults—if only for lack of suitable food sources, while the larvae feed on organic debris in cold, running water.
Diamesa sp. (winter midge)
March 29. What’s up, buttercup? Buttercups are popping up in the “more natural“ lawns of my neighborhood. We have a number of species buttercups in Missouri – this one is Ranunculus harveyi (Harvey’s buttercup). In general, you can distinguish buttercups by their small, bright yellow flowers and bristle of anthers surrounding the central disc.
Ranunculus harveyi (Harvey’s buttercup)
March 30. Bloodroot. I made a rather exciting wildflower find in the woodlands around my house this morning—a small patch of Sanguinaria canadensis (bloodroot) with (thus far) but a single bloom. This poppy relative (family Papaveraceae) is so named because of red, fleshy root, which gets its color from alkaloids, chiefly sanguinarine, in its toxic sap. First Americans traditionally used bloodroot to treat fever, rheumatism, ulcers, ringworm, and skin infections, and it is still used to produce natural red, orange, and pink dyes. There is likely some truth to the bioactive properties of bloodroot alkaloids, as they are currently being studied for use as anti-cancer agents, particularly for the treatment of skin cancer, and as a dissolving agent for skin growths such as warts. Bloodroot is also interesting from a natural history standpoint in that the seeds have fleshy appendages that are attractive to ants. The ants collect the seeds and bring them to their nest, thus effecting dispersal of the seeds. This is an advantage for these small plants growing in wooded habitats, where wind speeds are usually too low to aid natural seed dispersal.
Sanguinaria canadensis (bloodroot)
March 31. Sweet William. I saw these plants yesterday while their blooms were still closed and wondered if they would open before March closed out. I normally think of Phlox divaricata (sweet William) as a mid-April bloomer, but clearly it can begin earlier if conditions are right (as they have been the past several days).
Today the WGNSS Botany Group visited Little Lost Creek Conservation Area to see Dirca palustris (eastern leatherwood) in bloom. Leatherwood is a distinctive, slow-growing shrub that occurs sporadically in primarily the Ozark and Ozark Border region of Missouri. Like the much more Lindera benzoin (common spicebush), the flowers open in spring before the foliage appears, during which time the planta are easily identified by the pendulous blooms surrounded by wooly bracts. The species has toxic properties and was used by First Americans as an emetic, and it has been cultivated for many years despite its sporadic natural occurrence. As the name implies (palustris means “growing in a swamp”), the plant grows in moist (though not necessarily swampy) habitats, and as such we would have to hike across the dry-mesic upland deciduous forest and down into the riparian forests along Little Lost Creek where the plant can be found.
With sharply warmer temperatures arriving yesterday after a rather protracted cool period, the early-flowering trees and shrubs were ready and waiting, seemingly popping open before our very eyes. A patch of Prunus americana (American plum) in a more open area along the trail caught our attention, it’s blooms just beginning to open. We based our identification on the shrubby growth habit and apparently clonal nature of the stand of plants, which distinguishes P. americana from the closely related P. mexicana (Mexican plum), which generally grows as more tree-like individual plants.

Also in the more open areas along the trail was Rhus aromatica (fragrant sumac) in full bloom. I stopped to examine one particular individual with especially dense clusters of inflorescences and noticed movement on the flowers. Closer examination revealed a crab spider (family Thomisidae) which I took to be Mecaphesa asperata (northern crab spider)—perfectly camouflaged on the bright yellow flowers and awaiting the arrival of an unsuspecting bee or other pollinator.

As the trail veered directly into the forest, I noticed several butterfly species—a Vanessa atalanta (red admiral) that paused briefly on the trail before bolting erratically into the distance, several Eurytides marcellus (zebra swallowtail), presumably males patrolling for females among stands of the still leafless Asimina triloba (pawpaw) which it utilizes as a larval host, and—most interesting for me—several Anthocharis midea (falcate orangetip) which, for the time being, frustratingly refused to perch and allow even an attempt at a photograph.
As the trail began the long descent into the valley and the forest became increasingly mesic, spring ephemerals began appearing on the forest floor in abundance. Most abundant was Claytonia virginica (spring beauty) and Cardamine concatenata (cutleaf toothwort), which have been in bloom for some time now, but finally making their appearance as well were Sanguinaria canadensis (bloodroot)—the first seen being a charming little patch nestled against a rock—a single blooming plant among the stands of Erythronium albidum (white trout lily), and several still-unblooming Trillium sp. (wakerobin).

At last we reached the valley floor, and immediately the leatherwood plants were seen in abundance and in full bloom. Leatherwood plants in bloom are not among the showiest of blooming shrubs, but the distinctiveness of their flowers, sporadic occurrence, and lack of close relatives provided ample botanical interest that resulted in me spending a fair bit of time observing and photographing them.

As I looked at the leatherhood, I encountered a an unusual cocoon-like structure at the tip of one of its branches. Closer examination revealed it to be “packed” white tiny, white, grub-like larvae, at which time I noticed the cadaver of a moth caterpillar also clinging to the branch tip. I knew then that the grubs were the mature larvae of a parasitic wasp in the family Braconidae, likely in the subfamily Microgastrinae, that had just exited their host and were spinning cocoons nearby in communal fashion. (Many people have seen one of these wasps in the form of cocoons on the backs of tomato hornworm caterpillars.) Braconid wasps are often quite host specific, but a more specific identification is difficult since the identity of the caterpillar itself or whether it was utilizing Dirca as a host plant are also unknown.

If the spring ephemerals were abundant during the descent, they were overwhelming in the valley proper. A few blooming plants of Collinsia verna (blue-eyed Mary), a winter annual were seen, their distinctive bicolored white and blue flowers a pleasant contrast to the mostly white to pinkish color of the majority of the ephemerals. Some especially large-flowered individuals of bloodroot were seen underneath a patch of blooming leatherwoods, prompting me to spend a bit more time photographing them. As I was doing so, I found it ironically humorous that I was crouched on the ground photographing what is by all measures a rather common plant while surrounded by a much less frequently encountered plant.

The hike back up out of the valley was long and deliberate, the pitch in some stretches reaching as steep as I ever encounter on trails in the state, but the slow pace allowed an opportunity to look for things missed on the way down. At one point I picked up a fallen oak branch that looked like it might have been pruned by a twig pruner (Anelaphus sp.), a type of longhorned beetle (family Cerambycidae) whose larvae feed within living branches of deciduous trees—primarily oak—and then cut the branch internally before pupation. The cut end is distinctive, and I checked the base of the branch to see if it demonstrated this distinctive cut pattern. It did not, but I explained what I was looking for to a curious member of our group. Just as I finished the explanation, I saw another oak branch laying on the trail, picked it up to examine the base, and, sure enough, it exhibited the cut. I believe the branch is that of black oak (Quercus velutina), and I kept the branch to place within a rearing box so I can see the adult when it emerges later this spring.
Along the final stretch back to the parking lot, the falcate orangetip butterflies continued to torment me with their erratic, never-ending flight. I watched a few after reaching the parking lot, hoping one would alight and give a chance to photograph it, but no such luck. At the edge of the parking lot I noticed some Taraxacum sp. (dandelion) flowers with small insects on them, which turned out to be Acmaeodera tubulus—usually the first jewel beetles (family Buprestidae) to appear in the spring and commonly found on dandelions. I crouched to take a few photographs, and as I was doing so a falcate orangetip butterfly landed on the dandelion flower right next to the one with the beetles I was photographing. I managed to get one shot of the butterfly, it’s wings not well spread out but the orange tips still easily visible, before it took flight again—a nice punctuation to end the outing with.

For the past few years, I’ve been involved with the Missouri Native Plant Society (MONPS). To this point, however, my involvement has been limited to attending the monthly meetings of the St Louis Chapter—unfortunately, now only via Zoom since the beginning of the pandemic. I hope that soon we can return to in-person meetings (or, even better, a hybrid of the two, which allows person-to-person interaction without excluding participation by those who cannot attend in-person), but one activity that has resumed live are their periodic, multi-day field trips. The Spring 2022 Field Trip, held this past weekend in southwestern Missouri, was my first chance to participate in one of these events, and I looked forward to seeing the remnant prairies, limestone, dolomite, and sandstones glades, and chert woodland that were all on tap while rubbing elbows with some of the state’s best botanists and naturalists—some old friends and others new acquaintances!
Day 1 – Schuette Prairie I wasn’t able to make it to the actual Day 1, so I left St. Louis early in the morning to meet the group at the first stop of the following day—Schuette Prairie in Polk Co. Named after my friend and former Cuivre River State Park naturalist, Bruce Schuette, this recently acquired limestone/dolomite prairie with a wet swale contains many plants more typical of glades such as Silphium terebinthinaceum (prairie dock), Echinacea paradoxa (yellow coneflower), and Rudbeckia missouriensis (Missouri coneflower). Of course, on this cold, overcast, early-April morning, it was far too early to see any of these highly charismatic plant species (although some of the more astute botanists were about to point them out by their barely emergent foliage, which was easy to find in the recently-burned northern half of the parcel). Abundantly in bloom, however, was the more subdued Erythronium mesochoreum (prairie fawn lily, midland fawnlily, prairie dogtooth violet). Distinguished from the similar E. albidum (white trout lily) that occurs abundantly further east by its narrower, folded, usually unmottled leaves, all but a few of which remained stubbornly closed against the stiff, cold wind.
Precious few other blooms were seen—I recall somebody mentioning they had seen Viola sororia (common violet), and I photographed this little clump of Fragaria virginica (wild strawberry) that will eventually provide food for one of the area’s many box turtles.
Fragaria virginica (wild strawberry).
Speaking of box turtles, I found this completely naked, bleached carapace and at first hoped that it might have been from an ornate box turtle (Terrapene ornata)—limited in Missouri to western prairies and a species I have not yet seen. However, the presence of a midline ridge and its relatively more domed shape suggest it is from a three-toed box turtle (Terrapene carolina triunguis).
Many other carapaces were seen (though none in such good shape), and in fact bones of many types were easy to find in the burned portion of the prairie. This disarticulated skull from what appears to be a young calf (Bos taurus) was perhaps the most impressive bone find, but we did also find a dried skeleton of a smaller individual. Being the lone entomologist of the group, I just had to turn over the carcass and search for beetles and managed to capture a skin beetle (family Trogidae) and one other small unidentified beetle (but, unfortunately, no Necrobia rufipes [red-legged ham beetle]).

Rocky Barrens Conservation Area Later in the morning, the group caravaned to Rocky Barrens Conservation Area, a 281-acre area in Greene Co. featuring Mississippian limestone glades and site for the federally-endangered Physaria filiformis (Missouri bladder-pod). This plant, in the mustard family, is found only in four counties in southwest Missouri. The plants were readily found, but we were too early to see them in bloom—or anything else, for that matter. For me, however, the glade alone was still interesting, and I couldn’t help but take note of the similarities—and differences—between this limestone example and the dolomite glades south of St. Louis with which I am so much more familiar. Almost immediately, I noted the presence of Sideroxylon lanuginosum (gum bumelia), host for Plinthocoelium suaveolens (bumelia borer)—surely one of North America’s most beautiful longhorned beetles! I didn’t see any frass piles at the base of any of the trees, the presence of which would indicate larval activity, but I’m sure the beetle is here. It would be interesting to come back during the season and look for it. While I didn’t find any signs of the beetle, I couldn’t miss the bright orange-yellow gold-eye lichens (Teloschistes chrysophthalmus) colonizing it’s branches.

Another tree that caught my interest was Celtis tenuifolia (dwarf hackberry). I see these small, gnarly versions of the genus in glades and other xeric habitats, and they always catch my interest because of the diversity of interesting woodboring beetles associated with it. As I looked at the trees, I noticed one small tree in particular that was the perfect stage of dead—branches brittle but bark mostly still intact with a little bit of peeling on the trunk revealing woodboring beetle larval galleries underneath! There were only a few emergence holes present—strong evidence that the tree was still infested and worth bringing back to put in an emergence box to trap the emerging adult beetles. With luck, I’ll be pinning a series of Agrilus ferrisi next winter!
Corry Flatrocks Conservation Area After lunch at a nearby city park, the group caravaned to Corry Flatrocks Consevation Area in Dade Co.—site of another federally-endangered plant, Mononeuria minima (formerly Geocarpon minima) (tiny-Tim, earth fruit). The sandstone glades at this site are among the largest in the area and, thus, host a large population of the plant. By this time of day, the sun had been out for awhile and the day had warmed considerably, so we hoped to see other flowering plants as well. Among the first that we encountered while walking towards the glade proper was Ranunculus fascicularis (early buttercup), distinguished from other “large-flowered buttercups” by its canescent (grayish due to hairiness) leaves with long and narrow lobes, their tips bluntly pointed or rounded. The dry, gladey habitat also distinguishes the species from the similar R. hispidus (hairy buttercup), which flowers at the same time but prefers moister habitats.
Ranunculus fascicularis (early buttercup).
On the glade proper, we quickly encountered tiny little saxifrages in bloom, which turned out to be Micranthes texana (Texas saxifrage), restricted in Missouri to this part of the state (and thus with a high CC value of 9) and distinguished from the more widespread M. virginiensis (early saxifrage) by its small, compact stature. These first individuals we encountered had especially reddish-tinged flowers.

As soon as we reached the more open part of the glade with large expanses Of exposed rock, the group dropped to their hands and knees to find the diminutive plants we were looking for.

The plants were not uncommon, even abundant, in shallow, sand-filled depressions in the rock. Nevertheless, careful observation was still required to see and recognize them. Fortunately, the plants were already in bloom, their tiny styles barely visible to the naked eye within the green, not-much-bigger, petalless flowers. Photographing these plants, and especially those in bloom, proved to be a task almost beyond the capabilities of the smart phones that most in the group were using (me included).

The glades stretched on for quite a distance, inviting further exploration. At the margins, white flowering trees were noticed, and moving closer they proved to be Amelanchier arborea (downy serviceberry, common serviceberry)—among the first we have seen open this spring. (I typically see the first blooms of these trees in the final days of March, at least around my home in east-central Missouri.) an even closer looked revealed tiny insects (also among the first insects I have seen active this spring) flying around and crawling about on the flowers. These proved to be parasitic hymenopterans—family ID is still pending, but I suspect they will prove to be a species in one of the many families of “microhymenopterans” that are egg parasitoids. I am not sure whether they were visiting the flowers as pollinators (which behavior I am not aware of) or in hopes of encountering other pollinators which could potentially serve as hosts—a subject with which I will need to follow up.

Near the back end of the glade, we encountered a few more Micranthes texana (Texas saxifrage), these having more typical white flowers in perfect peak bloom.

Also in that part of the glade we found a few scattered individuals of Selenia aurea (golden selenia). While not quite as conservative as M. texana (CC value = 6), it has a similar range in the U.S. and in Missouri is also restricted to a handful of counties in the southwestern part of the state. The plant is known to occur in large colonies (which I have seen at nearby Corry Branch Glade)—its brilliant yellow flowers forming a spectacular display.
Selenia aurea (golden selenia).
To this point, the only insect I had seen besides the microhymenopterans was a skin beetle (family Trogidae), which I found when I kicked over some dried mammal scats. However, on the way back to the cars we finally encountered an insect large enough in size and striking enough in appearance to pique the interest of not just me but the group as a whole—a large caterpillar feeding on the foliage of Penstemon digitalis (smooth beard-tongue). It’s appearance—dark with longitudinal yellow stripes and blue spotting—immediately called to mind one of the tiger moths (formerly Arctiidae, now a subfamily in the Erebidae), specifically the genus Haploa (commonly called haploa moths). A little detective work on BugGuide comparing photos and recorded host plants narrowed the likely choice to H. confusa (confused haploa moth).

Day 2 – Lead Mines Conservation Area The final day of the MONPS Field Trip featured a morning trip to Lead Mine Conservation Area in Dallas Co. Of particular interest to the group were several parcels within the area designated as Niangua River Hills Natural Area and featuring a diversity of habitats including dolomite glades, chert woodlands, and calcareous wet meadows (fens). Most in the group visited the northern parcel to see the dolomite glades; however, a few of us—primarily from St. Louis and well-familiar with dolomite glades—opted to visit the smaller southern unit of the natural area to see the fen and riparian woodland we needs to pass through to get there. It was a much warmer morning than yesterday, though still chilly starting out, so blooms were sparse as we hiked the woodland trail searching for any hint of color. At one point, someone noticed a shrub a bit off the trail with large, reddish pink flowers—the color seeming a bit unexpected for the situation. Bushwhacking toward it, we realized it was Chaenomelesspeciosa (common flowering quince), a common, ornamental non-native plant that rarely—but obviously sometimes—escapes cultivation. While the group looked at the plant, I saw my first insect of the day—Paraulacizes irrorata (speckled sharpshooter), one of our largest and most recognizable leafhoppers, sitting head-down on the stem of a small sapling.
Paraulacizes irrorata (speckled sharpshooter).
Among the first native blooms we saw was Ranunculus hispidus (hairy buttercup). Though similarly “large-flowered” as R. fascicularis (early buttercup), it differs by its sprawling growth habit, differently shaped-leaves, and preference for moist habitats. Buttercups are a favorite flower host for jewel beetles (family Buprestidae) in the genus Acmaeodera, and one species —A. tubulus—is among our earliest-emerging beetles in the spring, so I checked each buttercup flower that I saw hoping to see these little beetles signaling the beginning of insect activity for the season. Sadly, none were seen.
Ranunculus hispidus (hairy buttercup).
At last we reached the fen—a large open area on the toe-slopes of the adjacent hillside where water draining through the underlying strata emerged to the surface to maintain a continually wet environment. The fen here is special, as two species of Cyprepedium (lady’s slipper orchids) are know to occur in the fen (and in fact, all four of the state’s Cyprepedium spp. can be found with Lead Mine Conservation Area). At this early date, the orchids would not be anywhere close to blooming; however, the group looked for evidence of their presence, walking gingerly through the fen so as to avoid inadvertently stepping upon any emergent foliage. No putative clumps were found, but already in my mind I’m thinking a mid-May trip back to the fen might be warranted! Unlike the orchids, Castilleja coccinea (Indian paintbrush) was abundantly evident throughout the fen, with an occasional plant almost ready to burst forth their scarlet blooms. Senescent flower stems of composites, presumably Rudbeckia, were also seen throughout the glade, which, combined with the abundance of Castilleja, created the promise of a stunning early-summer display across the fen.
Castilleja coccinea (Indian paintbrush).
During our time in the fen, two species of butterflies were seen flitting about the herbaceous vegetation: tiny blue Celastrina ladon (spring azure), and one of the dustywing skippers in the genus Erynnis. The former were impossible to photograph due to their persistent flitting and skittish behavior, and the latter almost were as well. Only when I locked the focus on a preset 2x zoom and fired shots in rapid succession while moving the smartphone ever closer to the subject did I manage this one imperfect but passable photograph of the last one I tried. The genus Erynnis is diverse and notoriously difficult to identify, and my expertise with skippers and butterflies pales compared to my skills with beetles, so the ID will have to remain Erynnis sp. until a more authoritative opinion is offered. [Edit 4/6/22, 11:38 am: According to my lepidopterist friend Phillip Koenig, Erynnis horatius and E. juvenalis both fly in early spring, and they cannot be reliably separated from the dorsal side. Erynnis juvenalis has one or two dots on the ventral hind wing that E. horatius lacks and only flies in the early spring, while E. horatius can be seen through the summer. If only I could turn the picture over to see what it looks like on the ventral side!]

Returning through the riparian woodlands after visiting the fen, the day had warmed considerably, and numerous flowers not seen earlier were suddenly in full bloom. These included Erythronium mesochorium (prairie fawn lily midland fawnlily, prairie dogtooth violet)—the same species we saw yesterday so reluctantly in bloom at Schuette Prairie. Most were of the familiar form with unmottled leaves; however, we found one individual with notably mottled leaves that resembled those of E. albidum (white dogtooth violet) (1st photo). Nevertheless, the leaves were still narrower than that species and folded, and the plant was growing a mere 12” from another individual with no trace of mottling (2nd photo).
Claytonia virginca (spring beauty) was also blooming in abundance as we took the trail back. I am always amazed at the variability seen in the flowers of this species—from pure white to vividly pink-striped to pink at the tips. This especially vivid pink individual was about as pink as they come.
Claytonia virginca (spring beauty)—an especially vivid pink example.
Sanguinaria canadensis (bloodroot) also was popping up regularly. We had seen isolated plants sitting the trailsides when we first part through—their flowers tightly folded in stubborn response to the chilly morning temperatures. By early afternoon, however, they were spread wide open as invitation to any of the flying insects that had surely also been awakened by the warmer temperatures of the afternoon. While most were seen as isolated individuals, a particularly idyllic clump captured our attention, almost begging “photograph me!”

With that, we rejoined the main group to recount the days experiences and cement new relationships before heading back towards our respective home areas.
Long Ridge Conservation Area On the way back home, I decided to check out this conservation area in Franklin Co., which I’ve never visited before. The afternoon had gotten quite warm, so I reasoned that maybe today would be the day when insects start coming out in abundance. I was right! As soon as I pulled into the parking lot, I saw a Prunus mexicana (Mexican plum) in full bloom, and walking up to it I immediately saw an abundance of bees and small beetles all over the flowers. The latter turned out to be Orsodacne atra (a leaf beetle) and Ischnomera ruficollis (rednecked false blister beetles).

Inside the woods along the Blue Trail, there were the usual suspects in bloom—Claytonia virginica (spring beauty), Cardamine concatenata (toothwort), Antennaria parlinii (Parlin’s pussytoes) and Ranunculus hispidus (hairy buttercups).

Eventually I happened upon an Amelanchier arborea (downy serviceberry) in full bloom. There were more O. atra and I. ruficollis on the flowers (though not so many as on the Mexican plum), along with a Mecaphesa sp. crab spider that had caught and was feeding on a male Andrena carlini (Carlin’s mining bee)*.

On the back third of the trail, I found two fallen branches under a Quercus shumardii (Shumard’s oak) that had been pruned by longhorned beetles—presumably Anelaphus villosus. At the end of the trail I found a third such branch of the same species of oak. All three will be placed in an emergence box, and hopefully the culprits will emerge as adults.

This is the 10th “Collecting Trip iReport”; this one covering 13 days of collecting in western Texas, southern New Mexico, and southeastern Arizona July 19–31, 2021. This trip was a “two-parter”—the first week with frequent field mate Jeff Huether (our seventh joint collecting trip) as we made our way from western Texas through southern New Mexico and into southeastern Arizona on our way to a memorial celebration for Jim Wappes at the home of Steve Lingafelter and Norm Woodley (for which I took the day off from collecting), and the second week visiting various locations in the “Sky Islands” of southeastern Arizona with several other entomologists.
Day 1 – Monahans State Park, Texas This was my first stop on the previous trip back in late April and early May, and what a difference a couple of months with good rains makes—dry as a bone then but bursting with a great variety of wildflowers now. Like last time we stopped at the Shin Oak Picnic Area first, and almost immediately Jeff got an Acmaeodera gibbula on living Prosopis glandulosa (mesquite). I started beating the trees and got a good series of that species along with a good series of an Actenodes sp. (prob. A. mendax). There were also some mesquites that had been killed (apparently by herbicide), and when I started beating them I got several more A. gibbula and one Paratyndaris sp. It went from blazing hot when we arrived to raining about an hour later, and for a while after the rain moved through it stayed cloudy and quite comfortable. Eventually we decided to look for another spot with more mesquite to beat.

We found an area closer to the entrance (Equestrian Area) with lots of mesquite and also sunflowers, which Jeff was interested in looking at to search for meloids (blister beetles). Before I even reached the first mesquite I saw an Acmaeodera sp. (maybe A. obtusa) sitting on the flower of Thelosperma megapotamicum (rayless greenthread) and later found another plus one A. immaculata. Off the mesquite I beat just one Actenodes sp. prob. mendax and a few treehoppers, while another and a Chrysobothris sp. got away (it was by now quite hot and they bolted!). I continued beating mesquite but just wasn’t seeing anything, so we decided to take a look at the area around the main dunes and another picnic area.
Helianthus petiolaris (prairie sunflower).
At the Pump Jack Picnic Area, we saw a lot of Thelosperma megapotamicum (rayless greenthread) in bloom and decided to check the flowers for Acmaeodera. We each got a nice series of what appear to be A. obtusa and A. immaculata. Also, I finally found a single Acmaeodera immaculata on the flower of Hymenoppapus flavescens (collegeflower), which I’d been looking at all day thinking it must be a good Acmaeodera flower host. On the way back to the vehicle, I scared up a cicada that had been singing on a nearby plant—I’d been hearing them all day but assumed they were grasshoppers or katydids. I listened for another and saw it perched on the stem of Mentzelia nuda (bractless blazingstar), and netted it—a fine male, smallish and with a very white venter. I wanted to find one more—catching another A. gibbula in flight, and saw one singing in a mesquite tree. This time I took some photos of it (working carefully not to alarm it) and then hand-caught it (later identified as Diceroprocta texana). A nice end to the visit.

After dinner, we returned to Shin Oak Picnic Area for night collecting. I setup my new Mercury-vapor (MV) station (first time using the gas-powered generator and tripod—slick setup) and my two ultraviolet (UV) stations. Jeff set out three prionic acid lures. Large numbers of Polyphylla monahanensis (which came mostly to the UV stations) and P.pottsorum (which came mostly to the MV station), but otherwise few beetles showed up and not a single longhorn. Other insects were also limited mostly to large numbers of ground-nesting bees and several big grasshoppers. No Prionus came to the lures—not surprising since we are in the tail end of the season for P. arenarius (April to July) and too early for P. spinipennis (mostly August). I’ve only gotten a few P. monahanensis and P. pottsorum before now, so it’s nice to have good series of each, but I would have preferred to collect some longhorns.

Day 2 – Toyahvale, Texas We’re on our way to the Davis Mountains, and along the way I decided to stop at the “Agrilus cochisei” spot we found (on a tip from Jason) back during the April trip. I swept the roadsides—not just the host plant (Artemisia occidentalis, western ragweed) but a variety of other plants in bloom but did not find any A. cochisei. I did collect a few meloids (which were on Solanum eleagnifolium) and Zygogramma leaf beetles but nothing else.
Proboscidea parviflora (family Martyniaceae)—doubleclaw or red devil’s-claw.
A bit further down the road from the last stop, we noticed this memorial to the many horses that have been transported along this highway on their way to slaughter.
Davis Mountains, Ft. Davis, Texas Another roadside stop for one of the places where I collected during last April’s trip. I was hoping we would not be too late for Acmaeodera—there were plenty of plants in bloom but we did not see any. Senegalia greggii (formerly Acacia greggii, commonly called cat-claw acacia) and Vachellia constricta (formerly Acacia constricta, commonly called whitethorn acacia) were both in bloom, and off the former I got the obligatory Stenaspis solitaria male/female pair as well as a Lampetis drummondii, but I collected nothing off the latter. Tried for a couple of cicadas and missed ‘em both!

Davis Mountains,Boy Scout Rd, Texas This looked like a good spot, with water in the creek and lots of butterflies flying around. Beating, however, yielded nothing but lots of lep larvae. It seems we are in the mid-summer lull—too late for spring things, but too early for late summer-fall species. I think we’ll try some higher elevations and see what it is like.

We were headed back towards the highway when I spotted a stand of Thelosperma megapotamicum along the road. We got out so I could take a look at them and immediately encountered this Texas horned lizard who seems to be saying “WTF?!” I swept through the Thelosperma and picked up two Batyle sp., one Enocleris sp., and a couple of species of meloids. There were lots of other plants in bloom, too, including several that are typically attractive to beetles such as Sphaeralcea and Ratibida. However, nothing was seen on them, further reinforcing our desire to go to higher elevations to see if that would improve the collecting.
Phrynosoma cornutum (Texas horned lizard).
Davis Mountains, Madera Canyon, Texas We wanted to get up to higher elevation to see if that might improve the insect collecting. It is strange—the Davis Mountains are greener than I’ve ever seen them, yet there are almost no insects, no flowers. Jeff and I were wondering if the deep freeze Texas experienced this past winter might have knocked out insect populations. We beat along the way but just we’re not seeing anything on the beating sheets. We hiked our way up to the overlook, and up there I ran into a few species of tenebrionids running along the trail and doing their famous “headstands” when we disturbed them. On the way back down I saw a few large, red and black clytrine chrysomelids on what I take to be a fall-flowering helianthoid aster (old flowering stalks were 5–6 feet tall), so I picked up a few for Shawn (my scope of insects that I’ll collect expands greatly when I’m not finding anything in the groups that I study). I think we’ve had it with the Davis Mountains, and tomorrow we’ll travel further west and try our luck around Fabens.

Day 3 – Van Horn, Texas Just a quick stop along the highway when we saw a variety of plants in bloom. Things are different at these lowers elevations compared to the Davis Mountains. Sweeping yielded a number of Agrilus sp. (vittate) and two Agaeocera gentilis—I suspect they were on the Sphaeralcea angustifolia (narrow-leaved globemallow), along with an Acmaeodera sp. and assorted other beetles. On a much taller globemallow I found two Tylosis jiminezi (male/female) perched on the foliage—a first for me! I did a little more sweeping further to the south but came up with only a few melyrids and a blister beetle (Epicauta segmenta). Nice stop!

San Felipe Park, El Paso Co., Texas When we first arrived, we were not at all optimistic—it looked like it hadn’t rained in years. However, the Larrea tridentata (creosote) and Prosopis glandulosa (mesquite) were both in full bloom, so we began looking about. Almost immediately I saw Stenaspis solitaria in the mesquites, which in itself is not exciting, but two of the first three I saw were the form that has the distinctly reddish-brown pronotum, which I’ve never seen before. I saw a couple more and tried to get photographs, but they were too skittish. As I searched for them, I caught one Aethecerinus latecinctus (a second got away), one Plionoma sp. (not sure if it’s suturalis or rubens), one Chrysobothris sp. (prob. C. octocola) and one Acmaeodera gibbula. The real fun began, though, when I walked by a creosote and saw a Gyascutus planicosta (should be subsp. obliteratus in this area) take flight. I tracked it to see where it landed, caught it, and then put most of my effort into getting a decent series of individuals. I succeeded, but it took more than four hours with the heat maxing out at 96°F! In addition to the Gyascutus, Jeff was quite excited to see the bright green and orange blister beetle Eupompha fissiceps abundant on the creosote in mating pairs and feeding on the petals of the flowers. I finished off the blister beetle fun by finding Cysteodemus wislizeni (black bladder-bodied meloid) crawling in the sand, which, despite the common name, was decidedly bluish.

After going into town to restock on supplies and catch some dinner, we returned to the park to do some lighting and night collecting. The moon is almost full, which generally puts the kibosh on longhorns coming to the lights, but we decided to try anyway because of the high amount of activity during the day in a rarely-visited location. I set up the Mercury-vapor (MV) light only and skipped going through the trouble to put up the ultraviolet lights also. I also wanted to beat the mesquite since I didn’t have much chance during the day, spending most of my time hunting Gyascutus with an aerial net, and once I got the MV setup going I started whacking the mesquite. Almost immediately, I got three Aethecerinus latecinctus, which came off the first two plants I beat. This motivated me further and caused me to commit to beating for the next hour or so—never even getting a single beetle of any kind! By then the lights had been going for awhile, and I was pleased to see several Derobrachus hovorei (palo verde root borer) crawling on the sand near the light. Even though it is a common species, I’ve not seen many myself, so I was happy to have a nice series to take up beaucoup room in one of my prionid drawers. Otherwise, very few beetles came to the lights, or most other insects as well—the sheet being covered primarily by dozens of white-lined Sphinx moths and lots of wasp/bee-type things. We did enjoy the evening, however, as we sat in our chairs and drank a cold brew between checkings of the light.

Day 4 – Chaparral, New Mexico We had planned to take NM-213 north to White Sands, but public access was blocked at Ft. Bliss. While backtracking, I spotted Sphaeralcea angustifolia (narrow-leaved globemallow) growing along the roadside and stopped to check it out. There was nothing on any of the plants, despite good growth and appearing to be coming into flowering. I did a little beating on Prosopis glandulosa (mesquite) as well—again very little going on, just a few treehoppers, tiny blister beetles, and one weevil. Larrea tridentata (creosote) was in full bloom, just like at Fabens, and here too there were many Eupompha fissiceps on the flowers and in mating pairs. I couldn’t resist collecting just a few and even made a short video of a mating pair engaged in some interesting behavior. I did see one Gyascutus planicosta as it flew by, but I could not track it to see where it landed. Otherwise all I picked up was another Cysteodemus wislizeni (black bladder-bodied meloid)—along with a photo, and a male cicada (maybe Diceroprocta texana) singing on a dry yucca stalk (hand-collected!).

Point of Sands, New Mexico Jeff wanted to stop here to look for Pleurospasta mirabilis, a really cool-looking blister beetle that looks unlike anything else. He found just one by disturbing the host plant (small purple blooms), and I found none—seems we are right at the tail end of their activity period. I looked around for other things also, but there was not much out. I did catch a couple more cicadas (males singing), and near an Ephedra sp. bush I found a mostly-intact carcass of Sphaerobothris ulkei. The most interesting find, however, was a couple of apparently lost pitfall traps—the barriers had fallen over, and the cops were filled with sand and the carcasses of numerous tenebrionids that had fallen into the traps and never been retrieved. I pulled up the cups and filled in the holes to prevent further loss, finding a few live tenebrionids and trogids and one Pasimachus sp. ground beetle that had not yet succumbed in the process.

Hatch, New Mexico While passing through the town of Hatch, I couldn’t resist taking the opportunity to stop and photograph some interesting town characters.

Deming, New Mexico Another roadside stop in an area that was green with flowers and also had Yucca (to look for Tragidion) and Ephedra (to look for Sphaerobothris). Neither of those insects were found, and no buprestids or cerambycids were seen on or swept from any of the many composite flowers about including Thelosperma megapotamicum. I did find a couple of the meloid Lytta biguttata, one on flowers of Cirsium sp. and another on an unidentified yellow composite flower, and Jeff found a huge aggregation of another meloid, Epicauta costata, on herbicide-treated Kali tragus (prickly Russian thistle). I finished off the stop by finding a spectacular ridged tenebrionid beetle walking about after the sinking sun went behind some clouds.

Day 5 – Sunshine, New Mexico We saw a nice stand of what proved to be Picradeniopsis absinthifolia (formerly Bahiaabsinthifolia, hairyseed bahia) and stopped to check them for buprestids/meloids. None were seen, just a few bees and lots of bee flies (genus Geron?). We did find a fair number of Cysteodemus wislizeni (black bladder-bodied meloid) crawling on the roadsides in a patch of Solanum elaeagnifolium (silverleaf nightshade).

Columbus, New Mexico We found a moist drainage along the roadside with plants blooming in abundance, including Isocoma tenuisecta (burroweed) and Sphaeralcea angustifolia (narrow-leaved globemallow); however, insects were very scarce. I didn’t see any buprestids or cerambycids at all on any of the plants, only picking up one Lytta biguttata and one Cotinis mutabilis on the Isocoma and sweeping single examples of a small black/red Cleridae from the latter and a yellow-flowered composite.

Animas, New Mexico We drove a fair distance west hoping to get into a different rainfall system in hope that insects would be present and saw a roadside in good bloom with the surrounding creosote scrub also green and blooming. As soon as we got out of the car we saw big beetles flying overhead and tracked them back to several creosote bushes very near the car with an aggregation of yet another blister beetle, Pyrota postica, which were mating and feeding on the flowers and leaves. After taking a few photos (and collecting my small series), I started sweeping through the variety of plants in bloom along the roadsides. I did not see anything on the flowers themselves (including Baileya multiradiata, pretty good buprestid flower) but collected a series of clytrine chrysomelids and one Dectes sp. While sweeping through Sphaeralcea hastulata (spear globemallow), I got one Agaeocera gentilis, and sweeping though a mix of S. hastulata and S. angustifolia (narrow-leaved globemallow) I got three Agrilus sp. (perhaps the same as I collected south of Van Horn, Texas). Finally, on the latter, I found one more A. gentilis perched on the leaf.

Portal, Arizona Finally made it to Arizona, and for the first stop I wanted to try a spot below Portal where I’ve had limited success finding Sphaerobothris ulkei on Ephedra. Last time I was I here I found a few, but not until after being distracted by Gyascutus caelatus and Hippomelas sphenicus in the acacias and mesquites. I vowed not to let that happen this time and weaved a zigzag pattern looking at every Ephedra I could find. While I was doing that. I did see one G. caelatus take flight and then caught another that I saw sitting on Vachellia constricta (white-thorn acacia) but remained focused on looking at the Ephedra. Eventually, after not seeing any S. ulkei, I started looking for other buprestids. The acacias were just beginning to flower—only a few plants had open flowers, and Jeff noticed the tiny silhouette of an insect in flight approaching the flowers. He netted it and showed it to me, and to my surprise it was one of the species in the A. stigmata group (black with two red apical spots)—none of which I have ever collected before but which I believe could be A. davidsoni. We spent the next hour watching for and netting the silhouettes on the few trees we could find with flowers, and then I got the beating sheet out and beat more off of the trees (whether in flower or not) to end up with a nice little series. I’ll be anxious to confirm whether these are A. davidsoni.

South of Willcox, Arizona We got to Willcox around dusk, and the cool, breezy conditions told my gut that it would be pointless to set up the lights. Still, I couldn’t let myself not try, and without much opportunity to look for a good place to set up I just went down Blu Sky Rd to E Moonlight Rd and hoped for the best. My optimism waned rapidly, as conditions continued getting colder and breezier, and not a single insect came to the light—I should’ve listened to my gut!

Day 6 – Jim Wappes Celebration, Hereford, Arizona Fun day with lots of fellow coleopterists at the home of Steven Lingafelter and Norm Woodley in memory of Jim Wappes. We got there in the early afternoon and enjoyed eats, conversation, and war stories from the field.

Day 7 – Superstition Mountains, Weaver’s Needle Vista Viewpoint, Arizona We awoke to rain yesterday morning in Willcox, and it has stayed with us since—first on our way to Hereford for the Wappes Celebration, then up to Phoenix this morning—our efforts to escape the rain by coming north thus proving futile. I came to this spot on a tip that I might find Agrilus cavifrons on Celtis pallida (spiny hackberry) (although maybe a bit early), and I’d hoped despite the light rain I would still be able to find it. I did not—though I found the plants, but I did get a Chrysobothris sp. that I don’t recognize while beating Senegalia greggii (formerly Acacia greggii, cat-claw acacia). Of course, it was on the first plant that I beat, so I ended up beating for another hour with nothing to show for it! While walking the short paved trail, I found Cercidium sp. (palo verde) tree that had been cut up and showed evidence of buprestid infestation in one of the larger branches, so I retrieved and cut it up for rearing.
Lost Dutchman State Park, Arizona We made a quick stop here to admire its incredible scenery before heading back south.

Upper Tanque Verde Falls Trailhead, Tucson, Arizona The rain finally moved out and it was sunny for the drive back to Tucson, but with still-cool temps we weren’t sure if lighting would be worthwhile. We decided to try this spot—not too high (based on a tip by Bill Warner), and I setup the lights using a technique recommended by Roy Morris that involved placing one ultraviolet (UV) light on each side of the sheet, extending the Mercury-vapor lamp above to the top of the sheet, and periodically shutting off the latter to allow the UV lights the pull in the “shyer” insects before turning it back on. While I waited for the lights to started pulling things in, I did some beating around the area. I only collected one specimen, but it was a Cleridae that I don’t recognize, which was beaten off of Prosopis glandulosa (mesquite). Temps ended up in the lower 70s to upper 60s, but at the lights we still got a few longhorned beetles (Aneflomorpha sp.), a few melolonthine scarabs, and a nice series of two species of Pachybrachis (that I will send to Bob Barney).

Day 8 – Atascosa Mountains, Ruby Rd near Atascosa Lookout Trailhead, Arizona The primary quarry here was Acmaeodera chuckbellamyi, a species I described in 2014 from a single specimen collected by my friend and hymenopterist, Mike Arduser, at this location on flowers of Aloysia sp. Several people have tried to find it since—without success, and in June 2011 the area was severely burned by the 27,550-hectare Murphy Fire. I was hoping enough time has passed to allow the area (and beetle population) to recover in this, my first attempt, at finding the species myself. I knew it was a long-shot, and long sorry short I did not find either the beetle or it’s Aloysia host flowers. I did collect a number of other beetles, however, including Lycus lorises, a few longhorned beetles and pachybrachine leaf beetles, and one Acmaeodera quadrivittatoides on flowers of Eysenhardtia orthocarpa (desert kidneywood), several Aneflomorpha sp. and a few pachybrachines on Quercus oblongifolia (Mexican blue oak), and more pachybrachines on Senegalia greggii (catclaw acacia), Mimosa dysocarpa (velvetpod mimosa)—the latter also yielding a few tiny Chrysobothris spp. (one looking like C. lucanus), and Propopis glandulosa (mesquite). Jeff also collected and gave to me a couple of Acmaeodera parkeri on flowers of Talinum aurantiacum (orange flameflower). I hiked 0.7 mi E on Ruby Rd to a spot where I swept a few beetles from low vegetation, and on the underside of a large, fallen branch of Q. oblingifolium I found a large female Polycesta arizonica. Finally, about halfway back to the trailhead I encountered a few tiger beetles on the road near standing puddles of water from the recent rains.

Atascosa Mountains, Peña Blanca Lake, Arizona We came here to look for Deltaspis tumacacorii, which like many rare beetles the odds are against finding it despite it having been taken in the area on several occasions. Again, this would not be one of those occasions, but I was happy to find a tiny tiger beetle (Cylindera viridisticta arizonensis) along the creek and even happier to beat a series of two species of Paratyndaris, one large Lampetis webbii (only my fifth specimen). and one Aneflomorpha sp. from mostly dead Senegalia greggii (catclaw acacia).

Huachuca Mountains, lower Carr Canyon, Arizona After dropping Jeff off at his hotel in Tucson (he flies home in the morning), I high-tailed it down to Carr Canyon to do some light collecting. It has been a long time since I’ve seen my sheet covered so quickly and thoroughly with insects! My quarry was longhorned beetles—of which I got a nice variety, but who can resist also the variety of scarabs, ground beetles, tenebrionids, blister beetles, and even planthoppers that flock to the lights in the mountains of southeastern Arizona? I’ll have to control myself a little better in the coming nights! Walking about along the roadsides (hoping to see Amblycheila giant tiger beetles), I encountered a gorgeous male Aphonopelma chalcodes (Arizona blonde tarantula).

Day 9 – Huachuca Mountains, Copper Canyon, Arizona I met Steve Lingafelter and Norm Woodley at their house, and together we drove to the famed Copper Canyon on the south side of the Huachucas. On the way I got a nice primer about the species that have been collected there and the plants they have been collected on. Steve and I started out walking the trail up the canyon while Norm swept the area down below. I pretty much beat every oak along the way, for a while only getting a smattering of beetles—Agrilaxia sp. on Quercus emoryi (Emory oak) and also on Q. arizonica (Arizona white oak) along with Sternidius decorus?. About a half-mile up the trail I beat dead branches of Q. hypoleucoides (silverleaf oak) and, not seeing anything at first, said “I’m going back; I’m literally not getting anything.” Right then, a small black beetle on the sheet caught my eye. I looked at it closely and realized it was a Mastogenius (prob. M. robustus)! I popped it in the bottle and beat more dead branches from the same tree and got not only another Mastogenius but also Tigrinestola tigrina. Freshly motivated, I spent the next half-hour working all the oaks in the area—and, as often happens, did not see another beetle! Nevertheless, it was hard not to be happy with the beetles that I’d gotten.

I walked back down the trail and met Norm, who was just starting up. He filled me in on the results from below, which included sweeping a few Agrilaxia hespenheidei—one of my target species—and an Agrilus sp. on Bouvardia ternifolia (firecrackerbush). I decided to work the slope under the road, reasoning that Norm had likely already worked the flat ground below. On the first B. ternifolia I approached, I saw an A. hespenheidei on the flower, gave the plant a sweep, and caught not only the A. hespenheidei but also an Agrilus sp. (maybe A. latifrons). Over the next hour I would sweep a nice series of A. hespenheidei from B. ternifolia (but not another Agrilus sp.). While I was doing that, I also swept the numerous stands of Acaciella angustissima (formerly Acacia angustissima, prairie acacia) looking for the large, spectacular Agrilus cavatus. I would find two, and considering that I swept perhaps 50 or more stands they were well earned. Also, in the meantime, I noticed Acmaeodera parkeri on small blue flowers that I eventually identified as Evolvulus arizonicus (Arizona blue-eyes). The flowers were few in number and the beetles difficult to catch, so I only ended up with two specimens. Further down the slope the flowers much more abundant, but there was not a beetle to be found on them. In the waning moments of my visit, I encountered two Trichodes peninsularis horni on flowers of Lasianthaea podocephala (San Pedro daisy).

Eventually we all met up at the car, compared our catches (not surprisingly, Norm did very well with buprestids and Steve did very well with cerambycids), and I did okay in both counts. We headed back over Montezuma Pass and were greeted with stunning views looking down into the Coronado National Monument!

Huachuca Mountains, Miller Canyon, Arizona After dropping Steve off, Norm and I went to nearby Miller Canyon to look at a spot where he has collected three species of Taphrocerus (I’ve only collected two, but only once way back in 1987 at a spot in the lower canyon). We thought it might be too late in the season, but it was at least worth a shot. The sedges were lush and green, but the “sedgy wedgies” were absent. Looks like I’ll have to just come back out in April or May!
After striking out with Taphrocerus, I went back down to the lower elevations of the canyon to look for Tragidion on the stand of Baccharis sarothroides (desert broom) that occurs there. Once again, I was likely too late to find them, but as with Taphrocerus it was certainly worth a shot, and again I would not find any despite looking and most of the large plants in the area. I did find a few Euphoria leucographa feeding on the sap flows and a very large red/black clytrine, so it wasn’t all for naught. Just another reason to come out earlier in the season.

Day 10 – Santa Rita Mountains, upper Box Canyon, Arizona After getting reports of buprestid activity near Madera Canyon, I decided to head to the Santa Rita Mountains today instead of continuing in the Huachucas. The shortest route to this most famous of canyons in the Santa Ritas goes down Box Canyon, a less-well-known but still-fantastic canyon in its own right and where I’ve had good luck collecting the two previous times I’ve been there (August 2018 w/ Art Evans, Steve Lingafelter, and Norm Woodley; and September 2019 w/ Jeff Huether). I stopped at the “dry falls” and worked my way back up the road to a point where I’ve collected the majority of my insects there. Along the way, I beat the flowering Eysenhardtiaorthocarpa (desert kidneywood)—insects were not numerous on the plants, but over the course of the trips up and back I got Acmaeodera gibbula, A. cazieri, two Aneflomorpha sp., and a few Lycus sp. I also swept the just-beginning-to-flower Mimosa dysocarpa (velvetpod mimosa) but got just a single Sphaenothecus bivittatus. When I reached the top of the canyon, I looked for a small patch of Allionia incarnata (creeping four-o’clock) in the steep road bank, off the flowers of which I have previously collected Acmaeodera cazieri, A. parkeri, and A. yuccavora. I found the patch, but the plants were not yet in flower. What was in flower on the flats above the bank, however, was Talinum aurantiacum (orange flameflower), off which I collected all three species (A. cazieri being the most abundant and only a single A. cazieri). As at previous stops this week, it seems that insect activity is beginning but is still a bit shy of coming into full peak.

While I was collecting, a caravan of cars came by. They turned out to be filled with entomologists attending the Invertebrates in Education Conference, one of whom I knew—Tad Yankoski of the Sophia M. Sachs Butterfly House in my hometown of St. Louis. He handed me a vial containing a large, live individual of Polycesta aruensis. I was excited to see this, especially when he told me he found it and saw many more in the flats below Madera Canyon, where I had planned to go next!
Santa Rita Mountains, flats below Madera Canyon, Arizona It was a frustrating afternoon on several fronts. Starting off, I had trouble finding the Polycesta aruensis locality, and when I finally did find it there was nary a Polycesta to be seen. Perhaps they sleep during the heat of the day.🤷 After that, there was little time to go anywhere but Madera Canyon, where I spent a half-hour beating Quercus oblongifolia (Mexican blue oak) hoping to see Chrysobothris chalcophoroides (I didn’t) and another two hours checking out Baccharis sarothroides (desert broom) in the area where I collected Stenaspis verticalis and Tragidion deceptus two years ago (also fruitless). Of course, the dreadfully common Stenaspis solitaria was everywhere, but all I ended up collecting was a tenebrionid on the 2-track, a clytrine beaten from Cercidium aculeata (retama), and one Euphoria leucographa along with a nondescript cerambycid (Heaperophanini maybe) on B. sarothroides. On the way back to the vehicle, I encountered a dead, mostly skeletonized deer, and while I rarely collect from carcasses, I noticed a little green beetle crawling on the jaw bone. I figured it must be the cosmopolitan clerid, Necrobia rufipes—something I’d not seen before, so I collected it and tried to collect but missed another one.

Santa Rita Mountains, lower Florida Canyon,Arizona I suppose I can credit my frustrating afternoon for one of my best nights of lighting ever. I stumbled upon this spot at the bottom of Florida Canyon during this afternoon’s Polycesta wild-goose chase and immediately thought, “Wow, what a perfect spot to set up a light!” A nice place to pull off the road with a small, level clearing embedded within low-elevation oak woodland. There was even a babbling creek in the background! It was close to dark by the time I returned and set up the lights (would’ve been even later if I’d gone into town for a “real” dinner). Ironically, there were neither the diversity nor quantity of beetles as two nights ago in lower Carr Canyon. But the cerambycids brought it… and kept bringing it! It seemed like every time I got up to check the sheet there were another 4–5 individuals. I ended up leaving the sheet up for four full hours and collected perhaps 40–50 specimens representing a dozen or more species. A few I don’t recognize, and most of those that I do recognize have resided in my cabinet in precious few numbers until now. It’s been years literally since I’ve had a night like this, and it’s a nice shot of motivation leading into the last few days of what is starting to feel like a long trip.

Day 11 – Madera Canyon Rd, Continental, Arizona I came back to the spot where Tad Yankoski had seen Polycesta aruensis so abundantly yesterday morning but which was completely absent by the time I got there in the afternoon. I did not see any adults on the trees this morning either and was about to give up when I spotted a few partially dead trees with very large, apparently fresh emergence holes in the main trunks that were the perfect size for P. aruensis—good thing I brought my chainsaw! I cut a trunk with its branches and segregated the cut up wood into age (fresh dead versus older) and size (twigs, medium branches, and main trunk) classes. While I was doing this, a Polycesta adult dropped off one of the fresh-dead, medium-sized branches! I beat the remaining branches on the tree and on nearby trees but did not see any more, so whatever Tad witnessed yesterday morning must have been an ephemeral event, perhaps related to synchronized emergence from the very trees among which I collected the wood. NOTE: don’t let anyone tell you that cutting up wood for rearing beetles is anything but a sweaty, exhausting endeavor, even with temps still in the mid-80s and decent cloud cover!

Santa Rita Mountains, lower Florida Canyon, Arizona I had such good night collecting here last night that I thought I’d come back and see what I could find during the day in this ribbon of riparian oak/hackberry woodland. Almost immediately I beat a Paratyndaris sp. off of dead Celtis reticulata (netleaf hackberry). The tree was very dead, but I knew Paratyndaris spp. like old, dead wood, so I split open some of the branches and found larvae inside and also a dead and unemerged but perfectly intact adult of a very tiny Chrysobothris sp. inside one of the smaller branches. Beating on other plants in the area was, in general, fruitless, but occasionally (and just often enough) I encountered something of interest that motivated me to continue working: Paratyndaris sp. and Agrilus sp. on Quercus oblongifolia (Arizona white oak), a small red/brown elaterid on Prosopis glandulosa (mesquite), and Acmaeoderopsis sp., Paratyndaris sp., and a few clytrines on Senegalia greggii (cat-claw acacia).

Santa Rita Mountains, Gardner Canyon, Arizona Last night, I got a message from fellow buprestophile Robert Velten, who told me that he would be in Gardner Canyon the next day, so after finishing at Florida Canyon I drove over to Gardner Canyon to meet up with him. Despite being longtime correspondents, Rob and I had never actually met face-to-face, so I was thrilled to have the chance to do so and spend some time with him in the field. Joining him were his mothing buddies Steve McElfresh and Paul Tuskes, and a little later our mutual friend and Arizona coleopterist-extraordinaire, Margarethe Brummermann, also joined us for a night of lighting. It was great to spend time at the lights with so many like-minded folks! There were three light stations between us, but the weather was less than cooperative—a persistent cool breeze accompanied constant lighting and thunder in the mountains above. Eventually, the threat was realized when the skies opened up, prompting a hasty dismantling and storage of all my lighting equipment safely inside the vehicle. Nevertheless, in the time that I was able to collect, I got a small number of longhorned beetles (half of which came to my light in the moments I was taking it down—longhorns typically become very active right before a storm) along with a variety of showy scarabs and clerids. The rain ended as quickly as it began, so the socializing continued. The entire evening I was continuously taunted, however, by a large prionid sitting inside its emergence hole on the trunk of a large Quercus emoryi (Emory oak). It only showed its jaws and antennae, and if I even touched the tree to boost myself up for a closer look it withdrew deep into the hole. I’m convinced it was Nothopleura madericus—a species I’ve never collected. I can still hear it laughing at me! My attempt to find one out and about by scanning the trunks and branches of of the other oaks in the area with my headlight was not successful, although I did collect another elaphidiine longhorn in such manner.

Day 12 – Santa Rita Mountains, Gardner Canyon, Arizona Rob had noticed a stand of Anisacanthus thurberi (desert honeysuckle)—a host for Spectralia cuprescens—along the road into Gardner Canyon, so together (after morning coffee!) we checked the spot on the way out. The plants were in the early stages of leafing out, and after visually inspecting them for a while and not seeing anything I decided to get out the beating sheet to sample the stand more thoroughly. My eyes did not deceive me—neither one of us found any. Too early? Low population? Who knows! I did beat one clytrine off the plants and collected a few weevils by beating Prosopis glandulosa (mesquite) before finding Acmaeodera parkeri and A. cazieri on the flowers of Allionia incarnata (creeping four o’clock). The flowers were common in the area around the road, but no Acmaeodera were seen until I started scaling the steep hillside nearby—a similar situation in which I’ve found these species on this flower in Box Canyon.

Huachuca Mountains, upper Carr Canyon, Reef Township Campground, Arizona I’ve been wanting to explore the higher reaches of Carr Canyon ever since I arrived in Arizona a full week ago. It is the only high canyon in the Huachucas that has a road leading all the way into its upper reaches. At these high elevations the forest is Pinus ponderosa (ponderosa pine) and Quercus hypoleucoides (silverleaf oak). There are many species of woodboring beetles at these high elevations that simply aren’t found down below. Another reason is the recent discovery up here of one of the rarest and most enigmatic of North American longhorned beetles, Placoschema dimorpha. Not even know to science until it was described from Mexico in 2007, it has since popped up here and a few other places in southeast Arizona—some of which have been heavily studied by coleopterists or many decades. Now, I didn’t actually <u>expect</u> to find such a rare thing, but maybe I could get lucky or at least find some other unusual species. The specimen at this location was photographed on a burned pine tree; however, I do not think that is the host (as far as I am aware, no species in the tribe utilizes gymnosperms as larval hosts). I think the host must be oak, as is the case for many trachderines. So, while I kept an eye out for burned pine trees, I also looked for oak, and especially recently dead oaks showing signs of woodboring beetle infestation. I did some of beating on Q. hypoleucoides and had collected just a clerid (Enoclerus bimaculatus) when I came upon a recently fallen Q. hypoleucoides that showed a few buprestid(ish) emergence holes and looked to be “the right age.” Cutting away the bark of the trunk revealed galleries, and chopping into sapwood revealed buprestid larvae in their galleries. I tagged it for retrieval, eventually cutting it up and segregating the trunk sections from the branches. Very nearby, I found another dead Q. hypoleucoides, this one much smaller and apparently cut rather than fallen. Unlike the previous one, however, this one showed the round holes with ejecting frass that indicated infestation by cerambycid rather than buprestid larvae. Cutting into the wood confirmed the presence of such, and so this one also was later cut up and bundled for bringing back. I saw no beetles on the trunks of any of the many fire-scarred pines lofting overhead, but at one point I spotted in the distance the telltale brown flagging of a recently died pine up the slope. Hiking up to it took some effort, but when I reached it the first thing I saw was a giant click beetle—Chalcolepidius apacheanus (Apache click beetle)—nestled against the ground at the base of the trunk (apparently ovipositing?). Inspecting the trunk of the tree itself, I noted just a few buprestid emergence holes that seemed fresh. Once again, chopping away the bark revealed the frass-packed galleries, and chopping into the heartwood revealed a large pre-pupal buprestid larvae. This was put into a vial, and I noted the location so I could return with the chainsaw and “bring ‘er down.” As I was cutting up the oaks, I found some small, recently cut pine branches near where I had parked the car. I found (and accidentally killed) a woodboring beetle larva of some type (I mangled it pretty good, but I think it was a buprestid) in one of them, so that was good enough to earn a spot in the rearing tubs. Unfortunately, I was not able to retrieve the dead pine tree—cutting up the oaks took a fair bit of time, during which darkening clouds gathered over the nearby peaks. Eventually cracks of thunder began piercing the air. It was all I could do to get the oaks into the car and all of the equipment put away before heavy rain drops began pelting the car. I had no idea what the storm would bring, but the last thing I wanted to be was stranded on the top of a mountain on my last full day of field collecting. As it turned out, the storm was more bark than bite (although the sharp drop in temperatures would kill lighting later in the evening). Perhaps I’ll be able to get back up the mountain in the morning and retrieve the pine tree.

Huachuca Mountains, lower Carr Canyon, Arizona It seems like forever ago that I began this trip, and now the last night of collecting has arrived. I decided to come back to this spot where I’d had such good luck earlier this week, but I wasn’t optimistic given how rain chased me out of the canyon earlier. My pessimism was warranted, and while I did picked up a variety of things, it included only two longhorns—both rather pedestrian species. No, the real charm of the night came not from collecting insects, but after the lights were down and my mind was free to wander as I leaned back in my chair and gazed into the crisp, dark, starry Arizona sky—its perimeter along the horizon bound by a craggy silhouette of nearby oak trees and distant peaks; from listening to the sounds of the night, alternately focusing on the individual cricket or distant coyote versus the chorus as a whole. Only to the north could I see the faint glow of city lights—the only sign that anything beyond me and this moment exist. These moments happen only once on a trip (maybe twice), and they are to be savored; indelibly stamped into the memory banks for future enjoyment; one of those experiences that, when recalled, is guaranteed to trigger euphoric recall.

Day 13 – Huachuca Mountains, upper Carr Canyon, Reef Township Campground, Arizona I went back up to the top of Carr Canyon to retrieve the dead Pinus ponderosa that I found yesterday. Good thing I did, as I also found my favorite hatchet (which I’d inadvertently left behind yesterday). The 9” diameter trunk was almost too big a job for my Stihl MiniBoss chainsaw, but I kept at it and finally felled the the 25’ tall tree. It took three trips up and down the steep slope—each round trip almost a half-mile—to haul out the upper 10 ft of trunk and associated branches, which I segregated into three batches for rearing: trunk, 1–2” día. branches, and <1” dia. twigs. Now let’s hope the effort was worth it and I get some good species out of the wood.

You can see the road that I traveled up this morning snaking back down the right side of the mountain. The massif to the left is the highest point that you can see from the valley below, but there are much higher peaks behind me.

Epilogue Sadly, I could squeeze no more stops into the trip—I’d allowed myself two days to make the 24-hour drive back to St. Louis, and it was already almost noon on the first of the two days. I left, however, with a rack full of vials filled with insects and a renewed love for Arizona and the desert southwest that first captured my heart some 37 years ago!
Last Saturday, the Webster Groves Nature Study Society (WGNSS) Nature Photography Group was joined by several members of the WGNSS Botany Group and Missouri Native Plant Society to look for one of Missouri’s rarest plants—Geocarpon minimum, a.k.a. tinytim or earth-fruit (family Caryophyllaceae). This diminutive, federally-threatened and state-endangered plant grows only on sandstone glades, primarily in west-central Missouri with a few populations known also from Arkansas, Louisiana, and Texas. The window for finding this plant is short—it’s entire life cycle lasts only about 4 weeks, with an even shorter window for finding it in flower.
Our first stop to look for them was Bona (pronounced “Bonnie”) Glade Natural Area. I’d been here before, but it was about 10 years ago and at the wrong time to look for this plant (but I did find widowscross, Sedum pulchellum, in bloom). Some of the group had seen it here before and were able to coach us on the microhabitat where we would likely find them, and it didn’t take long before we did. Soon after finding the first plants, we found them in bloom as well—their almost microscopic flowers being the perfect subject for my macro lenses!

After getting plenty of shots of the plant and flowers, we moved to an adjacent plot of land across the highway, where we not only found more tinytim plants but also Corydalis aurea, commonly called golden corydalis (pronounced koor-ID-uh-lyss), in the family Papaveraceae—something I’d never seen before.
Next the group moved on to Corry Branch Glade. It was originally our intent to look for more of the plant at this site, but immediately upon entering the glade we noticed a stunning display of Selenia aurea, or golden selenia. This small, striking species in the mustard family is restricted to just a handful of counties in the west-central part of the state, again primarily glade habitats. It was a surprising and pleasant find that occupied the groups’ attentions for some time before we finally decided to break for lunch (it was well into the afternoon!). While I was there, I not only photographed the plant but started having some success with my new 15-mm wide-angle macro lens, with which I had been experimenting all day (to that point without much success).
Members of WGNSS & MoNPS go hunting for rare plants! Front to back: Ted MacRae (me), John Oliver, Casey & Anh Do Galvan, Steve Turner, Bill Duncan, David Seidensticker, Deb Tyler, Adam Rembert, and James Faupel.
After “lunch” (which was closer to dinner!), a few of us (Bill, David, and I) wanted to go back to Bona Glade to take another crack at photographing tinytim with our wide-angle macro lens. I especially was not satisfied with what I had gotten earlier, that being my first serious attempt at using the lens in the field. Having a better idea now of how to use the lens and what our compositional goals were, we scoured the area looking for just the right plants in just the right situations. I can honestly say I finally got a feel for how to use the lens, the trickiest part of it being how to balance use of flash on the subject with the amount of ambient light from the background (I’m not a stranger to this concept at all, frequently having combined flash with “blue sky” in much of the macrophotography I’ve done up to this point). We photographed several plants on different substrates looking for the right combination of plant, substrate, and background, and we all walked away pretty optimistic that we’d gotten the photos that we wanted.

My thanks to Casey and Ando Galvan for letting me ride down there with them, to David Seidensticker and Bill Duncan for letting me ride back with them, and for everyone in the group who so generously shared their great, collective knowledge of botany, photography, and natural history. What a fun day!

Hot on the heels of the previous installment in this series, I present the sixth “Collecting Trip iReport”; this one covering a trip to Arizona during July/August 2018 with Art Evans and—like the previous installments in this series—illustrated exclusively with iPhone photographs (see previous installments for 2013 Oklahoma, 2013 Great Basin, 2014 Great Plains, 2015 Texas, and 2018 New Mexico/Texas).
This trip was a reunion of sorts—not only had it been 20 years since I’d collected in Arizona, it had also been 20 years since I’d spent time in the field with Art Evans—which just happened to be in southeast Arizona! For years I looked forward to our next opportunity, and when he told me of his plans for an extended trip to take photographs of his forthcoming Beetles of the Western United States, I couldn’t pass up the chance. Art had already been out west for five weeks by the time I landed in Phoenix on July 28th, and together we drove to Cave Creek Canyon in the Chiricahua Mountains and spent the night before beginning a 7-day adventure in and around the “Sky Islands” of southeastern Arizona.
As with the recent New Mexico/Texas post, the material collected still has not been completely processed and curated, so I don’t have final numbers of taxa collected, but there were a number of species—some highly desirable—that I managed to find and collect for the first time, e.g., the buprestids Acmaeodera yuccavora, Agrilus restrictus, Agr. arizonicus, Chrysobothris chiricauhua, Mastogenius puncticollis, and Lampetis webbii and the cerambycids Tetraopes discoideus and Stenaspis verticalis. Who knows what as-yet-unrecognized goodies await my discovery in the still unprocessed material?!
Day 1 – Chiricahua Mountains, Cave Creek Canyon
After arriving at Cave Creek Ranch late last night, we awoke to some stunning views right outside our room!

The first buprestid of the trip was a series of Pachyschelus secedens on Desmodium near Stewart Campground. We beat the oaks and acacia along the way to Sunny Flat Campground but didn’t find much. Once we got near Sunny Flat I did some sweeping in an area with new growth of Helianthus sp. and got a series of Agrilus huachucae, a few lycids, and one Leptinotarsa rubiginosa. I beat one Acmaeodera cazieri from Acacia greggii and found another on flower of prickly poppy (Argemone sp.). On the roadside at Sunny Flat I found several Acmaeodera spp. on a yellow-flowered composite – one A. rubronotata, one A. solitaria(?), and three A. cazieri. Also collected one A. cazieri on a rain gauge, Mecas rotundicollis and one as yet undetermined acanthocinine cerambycid on miscellaneous foliage, one tiger beetle (Cicindela sedecimpunctata?) on the roadside, and two orange lycids in flight.

We came to this spot to look for Sphaerobothris ulkei on joint-fir (Ephedra trifurca), but after not finding any for awhile I got distracted by some big buprestids flying around. Caught several Hippomelas sphenicus, one Gyascutus caelatus, and two Acmaeodera gibbula on Acacia rigida, and the first and third were also on Prosopis glandulosa along with Plionoma suturalis. We finally found S. ulkei – searched the area for almost three hours, and Art and I each caught two and Margarethe caught one – also one each of P. suturalis and A. gibbula. I also got a mating pair of A. gibbula on Acacia greggii. After dinner, we went back and placed an ultraviolet light – checked it a couple hours later and got a nice series of Cylindera lemniscata and a few meloids (for Jeff).

Day 1 of the trip ended in typical monsoon fashion – heavy, thunderous rainstorms moved into the area during late afternoon, dimming prospects for blacklighting. Still, we set them up anyway at several spots and checked them later in the evening (flood waters preventing us from going to all the spots we wanted to). Not surprisingly, the one trap that yielded interesting specimens was in the lowest (warmest) area and received the least amount of rain. For me it was a nice series of Cylindera lemniscata.
Day 2 – Southwestern Research Station, Chiricahua Mountains, Arizona
There is a large stand of a narrow-leaved milkweed (Asclepias sp.) at the station, so we stopped by in our way up the mountain to check it for beetles. Got a nice little series of Tetraopes discoideus (tiny little guys!) on the stems as well as a few Rhopalophora meeskei, two Lycus spp., and one Pelonides humeralis on the flowers.

Road from Southwestern Research Station to Ruster Park After leaving the SWRS on our way up to Rustler Park, we stopped to check a couple of bushes of New Mexico raspberry (Rubus neomexicanus). Margarethe thought there might be lepturines on the flowers, but instead we found a few Acmaeodera spp. and some Rhopalophora meeskei.

Gayle Nelson once told me about finding Chrysobothris chiricahuae on pine slash at Rustler Park, so I was pleased to see several fresh slash piles when we arrived. I saw a Chrysobothris (presumably this species) on the very first branch in the very first pile that I looked at, but I missed it (damn!) and didn’t see any more in that pile. However, in the next pile I visited I saw two and got them both. I looked at a third pile and didn’t see any, nor did I see any more on the two previous piles that I looked at. Still, two is better than none (assuming this is, indeed, what they are!).

Chiricahua National Monument
Not a bug collecting stop, but we wanted to drive into the monument and see the incredible rock formations which are best appreciated by driving through Bonita Canyon and then up to Massai Point. The unusual spires, columns, and balancing rocks are a result of erosion through vertical cracks in the compressed volcanic ash which was laid down in layers 25 million years ago and then uplifted. Tilting during uplift caused vertical fractures and slippage, into which water then worked its way to create today’s formations. One of the columns I saw is 143 feet tall and only 3 feet in diameter at one point near the base! Mexican jays were our constant, close companions as we hiked through the pinyon pine/oak/juniper woodland.
Vicinity Gleeson, Arizona
There is a wash across N Ghosttown Trail with stands of Baccharis sarothroides growing along the sides. Art previously collected a single Cotinis impia on one of the plants, so we came back to check them. We didn’t find any, but we did find two fine males and one female Trachyderes mandibularis on a couple of the plants. I also found a dead Polycestaaruensis.
Vicinity Tombstone, Arizona
Art saw Gyascutus caelatus here previously, so we came back and found them abundantly in sweet acacia (Acacia rigidula), which was in full bloom. They were extremely flighty and hard to catch, so we each got only four. I also collected one Stenaspis solitaria on the same and a Trachyderes mandibularis female in flight.

At another spot nearby, we stopped to look for Lampetus webbii, which Art had seen but not been able to collect when he was here a couple of weeks ago. We did not see any (but read on…), and I saw but did not collect a Trachyderes mandibularis and two Stenaspis solitaria. I also saw and photographed some giant mesquite bugs (Thasus neocalifornicus).

Day 3 – Box Canyon, Santa Rita Mountains, Arizona
Our first stop of the day was Box Canyon, a gorgeous, rugged canyon on the east side of the range. Mimosa dysocarpa was in bloom, off which I beat two Agrilus aeneocephalus, several Hippomelas planicauda, and one Stenaspis solitaria. Norm gave me an Acmaeodera cazieri that he’d collected on an unidentified yellow-flowered composite, and right afterwards I found some small, low-growing plants with purple flowers and sticky leaves (eventually ID’d as Allionia incarnata, or trailing four o’clock) to which Acmaeodera yuccavora and A. cazieri were flying in numbers. After that I crawled up top and beat the mesquites, getting one Chrysobothris sp., a mating pair of S. solitaria, and a couple of large clytrine leaf beetles.

Vicinity Duquesne, Arizona
We came here to look for Tetraopes skillmani (this is the type locality). We found the host plant (Sarcostemma sp.), but there were no beetles to be seen anywhere. Maybe another location nearby…
Sarcostemma sp. (family Asclepiadaceae).
Patagonia Pass, Patagonia Mountains, Arizona We went up higher into the mountains to get into the oak woodland, where I hoped to find some of the harder-to-collect oak-associated Agrilus spp. Right away I beat one Agrilus restrictus off of Emory oak (Quercus emoryi), but no amount of beating produced anything more than a single Enoclerus sp.. I also beat the Arizona oak (Q. arizonica) and got only a single Macrosaigon sp. On Desmodium sp. I collected not only Pachyschelus secedens but a nice series of Agrilus arizonicus. For me it is the first time I’ve collected either A. restrictus and A. arizonicus, the former being quite uncommon as well, so all-in-all not a bad stop.

Sycamore Canyon, Santa Cruz Mountains, Arizona
We came here for night lighting, but while we still had light I did some sweeping in the low vegetation and collected a mixed series of Agrilus arizonicus (on Desmodium sp.) and Agrilus pulchellus – the latter a first for me, along with two small cerambyids that could be Anopliomorpha rinconia. Conditions were perfect (warm, humid, and no moon), and we had lots of lights (Art’s five LED units, Steve’s MV/UV combo setup, and my UV setup), but longhorned beetles were scarce – just one Prionus heroicus and one Lepturges sp. for me, and Steve got a few others including a nice Aegomorphus sp. I did also collect a few scarabs – Chrysina gloriosa and Strategus alous – because they’re just so irresistible!

Day 4 – Prologue One of the downsides (if you can call it that) of having great collecting is the need to take periodic “breaks” to process all the specimens and make my field containers available for even more specimens. Thanks to Steve and Norm for making their place available to Art and I so we can do this before heading out to our next set of localities.
Copper Canyon, Huachuca Mountains, Arizona
Copper Canyon is the classic spot for finding the charismatic Agrilus cavatus (see photo), but first we did some sweeping in the low vegetation near the parking area, where Norm got one Agrilus arizonicus and two Agrilus latifrons – and gave them to me! (Thanks, Norm!) I did some beating of the oaks, and after much work I ended up with a single Agrilaxia sp. and pogonocherine cerambycid on Emory oak (Quercus emoryi) and a couple of giant clytrines on the Arizona oak (Q. arizonicus). I then started sweeping the low-growing Acaciella angustissima – right away I got two A. cavatus. They were in the area past the cattle guard on the right where lots of dead stems were sticking up, and although I continued to sweep the plants more broadly in the area I never saw another one. Finally, Norm called me up to a small Mimosa dysocarpa near the car off which he collected three Agrilus elenorae – and gave them to me! (Thanks, Norm!) I gave the tree a tap and got one more, and in my last round of sweeping I came up with a Taphrocerus sp. (must be some sedges growing amongst the grasses).

Bear Canyon Crossing, Huachuca Mountains, Arizona
There was quite a bit of Mimosa dysocarpa in bloom along the roadsides on the west side of the Bear Canyon crossing, which I beat hoping to find some more Agrilus elenorae. I didn’t find any, but I did get several more Hippomelas planicauda, which is a nice consolation prize – and a great photo of the last one! Other than that I did a lot of sweeping and found only a single Acmaeodera cazieri.

Cool temperatures and a blustery wind discouraged most insects from finding our blacklights. However, our blacklight did find some other interesting local residents. These two individuals could be the stripe-tailed scorpion, Paravaejovis (Hoffmannius) spinigerus, a common species in Arizona and southwestern New Mexico.
Day 5 – Miller Canyon Recreation Area, Huachuca Mountains, Arizona
There was a lot of Baccharis sarothroides growing in the lower canyon near the parking area, so I checked it all out hoping to find Tragidion annulatum. None were seen, and in fact there was very little insect life in general. I did pick up a couple of Acmaeodera solitaria by sweeping – not anything significant but the 15th species buprestid of the trip and found a dead Cotinis mutabilis, and Art got a nice series of Chalcolepidius click beetles on B. sarothroides and Prosopis glandulosa. Puzzling the lack of insect activity, given how green all the plants were and how fresh the growth looked. I guess we’ll have to look elsewhere.

Vicinity Naco, Arizona
We decided to try some desert thorn-scrub habitat so headed east towards Bisbee. Just north of Naco we saw some habitat where it had rained recently – everything was green with the sweet acacia (Acacia rigidula) and creosote (Larrea tridentata) in full bloom. Immediately out of the car I found a Dendrobias mandibularis on Baccharis sarothroides (and when I came back to it later I found a big, major male on it – see photos). On the sweet acacia we found a handful of Gyascutus caelatus (one of which I got a nice photo of), a mating pair of Sphaenothecus bivittatus, and a Cymatodera sp. Finally, out along the roadsides a riot of different yellow composites were in full bloom, including Heliomeris longifolia off which Art got a couple of Acmaeodera solitaria and I got two specimens of a large Acmaeodera sp. (blue-black with numerous small irregular yellow spots).

Vicinity Tombstone, Arizona
We decided to go back to the spot north of Tombstone where Art had earlier seen Lampetis webbii and give that species another shot. We looked at the Rhus sp. tree that he’d seen them on, and then we each followed the wash in opposite directions looking at the Rhus trees along them, which growing above the banks but never further away than about 25 feet. Along the way I collected several more Gyascutus caelatus on sweet acacia (Acacia rigida), which were more abundant this time than last and also easier to catch. After walking about 1/4-mile down the wash I saw something fly from a Rhus tree and land low on the bushes nearby. I quickly netted it, pulled it out, and was elated to see that it was, indeed, Lampetis webbii! I searched the Rhus in the area more carefully but didn’t find any more, then found some Rhus growing up along the road. At one point, I saw a large buprestid fly and land high in the top of another Rhus tree. I couldn’t tell for sure if it was L. webbii, but I extended my net as far as I could, positioned it beneath the beetle, and tapped the branch hoping it would fall in. Unfortunately, it flew away instead of dropping, so I can’t say for sure whether it was L. webbii or just a wayward G. caelatus. At any rate, L. webbii is yet another species that I have not collected before now and the 17th buprestid species of the trip.

Ramsey Canyon, Huachuca Mountains, Arizona
After returning from Tombstone, we visited Pat & Lisa Sullivan at their home at the end of Ramsey Canyon. Pat is a scarab collector who runs lights at his home nightly, and after a delicious dinner we spent the rest of the evening checking the lights. I was hoping to collect Prionus heroicus, and I got my wish. Also got Prionus californicus and several other non-cerambycid beetles such as Chrysina beyeri, C. gloriosa, Lucanus mazama, and Parabyrsopolis chihuahuae (the latter a first for me). I also placed a prionic acid lure (thanks Steve!) and got three more male P. heroicus. We also hunted around the rocks and roadsides hoping to find Amblycheila baroni but didn’t find any. Art did, however, find a female P. californicus and gave it to me (thanks!).

Day 6 – Vicinity Sonoita, Arizona
Unsuccessful attempt to collect Hippomelas martini, only recently described (Bellamy & Nelson, 1998) and part of the type series taken somewhere near this spot (“20 mi NE Patagonia, Hwy 82”) by “sweeping roadside vegetation”. At other locations it had been recorded on Calliandra sp., and I found patches of the plant here along and on top of the road cuts. This gives me confidence that I found the right spot, but I didn’t encounter this or any other beetles by sweeping the patches or visually inspecting them.
Box Canyon, Santa Rita Mountains, Arizona
We decided to come back to Box Canyon since we’d had such good luck last time. I started at the spot above the dry falls where I collected so many Acmaeodera cazieri and A. yuccavora on flowers of Allionia incarnata. This time it was hotter, drier, and windier, and the flowers were semi-closed. Still I found a few of each. I then started walking down the road towards the lower canyon crossing where I would meet up with Art. Things were really hopping on the Mimosa dysocarpa, with Hippomelas planicauda abundant (finally collected my fill) and several other Buprestidae also beaten from the plants: Agrilus aeneocepahlus, Acmaeodera scalaris, Acmaeodera cazieri, Chrysobothris sp., and a species of Spectralia! (seven species of Buprestidae at one location I think is the high for the trip.) I checked other plants and flowers along the way down but didn’t find much.

Lower Madera Canyon, Santa Rita Mountains, Arizona
Madera Canyon is perhaps the most famous insect collecting locality in Arizona – maybe in the country, and it is hard to make a visit to Arizona without stopping by here. We elected to work the lower canyon first in an area where Chrysobothris chalcophoroides has been taken on Arizona oaks (Quercus arizonicus). Hiking towards the oaks I found some Stenaspis solitaria in a Baccharis sarothroides and marveled at the variety of other insects active on the plants (see photos) – later I would also collect an elaphidiine cerambycid on the plant. Next I started working the oaks, beating every branch I could reach with my net handle. With one whack of the stick a single Paratyndaris sp. and a single Brachys sp. landed on my sheet – those would be the only buprestids I would collect off the oaks! Other than that I collected one Hippomelas planicauda on Mimosa dysocarpa for the record. While I was working the oaks up in the knoll, the weather started turning with blustery winds, and I could see the rain coming in the distance. By the time I got down from the knoll the rain had arrived, and I walked back to the car in a sunny downpour using my beating sheet as an umbrella!

Montosa Canyon, Santa Rita Mountains, Arizona
Just to try something different, we went to Montosa Canyon – the next canyon south of Madera Canyon – for tonight’s blacklighting. We set my sheet up just E of the crossing and Arts ground units back to the west along a gravel road on the south side of the crossing. Moths came in numbers, but the beetles were light – I collected only blister beetles (Epicauta sp.) and a Cymatodera sp. checkered beetle at the sheet, a series of tiger beetles and a female Strategus cessus at the second ground unit, and a male Strategus aloeus and two Stenelaphus alienus at the third ground unit.

Day 7 (last day) – Vicinity Continental, Arizona
There was a photo posted on BugGuide of Stenaspis verticalis taken last week, so we decided to give it a shot and see if we could get lucky and find it ourselves. We checked all the Baccharis sarothroides within ½-mile if the spot but didn’t find it. I did, however, collect four Euphoria leucographa, two Chalcolepidius smaragdula, two Aneflus spp., and singletons of Stenaspis solitaria and Dendrobias mandibularis. I also took a couple of Hippomelas planicauda on Mimosadysocarpa – just for the record!

Lower Madera Canyon, Santa Rita Mountains, Arizona
We returned to work the lower canyon area. I’d heard that the tiger beetle Cicindelidia obsoleta santaclarae has been taken in the area last week so was hoping to run into it. While Art worked the east side of the road I worked the west, initially following FR-781 into what looked like grassland areas where the tiger beetle might occur. I didn’t see any but took Acmaeodera scalaris on Heterotheca sp. flowers and Acmaeodera solitaria on Argemone mexicana flowers. There was also a fresh wind-thrown mesquite (Prosopis glandulosa) with a bunch of Chrysobothris octocola and one Chrysobothris rossi on it. Still the area looked abused from grazing and was uninteresting, so I looked for another area to explore.
Northwest of the parking lot I spotted another grassy area that was dotted with Baccharis sarothroides, so I decided to give that area a look. After clambering several times through barbed wire fence, I reached the area and began to give it a look. Still no tiger beetles, but every time I passed a B. sarothroides I inspected it closely. I’d looked at several plants when I came upon one with a Stenaspis solitaria sitting in the foliage, and when I looked down on one of the stems and saw a big male Tragidion sp. on the underside of the stem. After securing it, I looked closer at the plant and saw a pair of annulated antennae crawling up another stem – I knew right away it was a mating pair of Stenaspis verticalis! After carefully moving to the other side to confirm, I dared to take a few photos in situ (see below) and then secured the couple. Of course, this gave me newfound motivation to work the entire area to look for more. It was very hot by then, and I was already quite thirsty, but I summoned up all the stamina that I could and worked as many plants as I could, ending up with six Tragidion spp. and three Stenaspis verticalis. The latter was one of my top priority targets for this trips, and the only thing more satisfying than getting it is doing so on my last day on the field.

Montosa Canyon, Santa Rita Mountains, Arizona
We returned to Montosa Canyon and stopped at the Astronomy Vista partway up. It was hotter than bejeebuz! There was not an insect to be seen except giant cactus bugs and a single Euphoria leucographa that Art found on a sapping Baccharis sarothroides. Temp was 103°F even at this elevation!
Stunning vista during the day!
We needed to escape the heat, and I wanted to see oaks for one more crack at Mastogenius, so we drove up to the 13-km marker and I collected on the way back down to below the 12-km marker. Conditions were much more agreeable (temps in the 80s), and near the top there was a Ceanothus sp. bush in bloom, off which I collected Rhopalophora meeskei and Stenosphenus sp. – both genera represented by individuals with black versus red pronotum. Then I started beating the (Mexican blue, I believe) oaks, and right away I got a Mastogenius sp.! Kinda small, so I’m thinking not M. robusta and, thus, probably M. puncticollis (another species new to my collection). I also beat a largish Agrilus sp. that I don’t recognize, a few clerids, two R. meeskei, one Stenosphenus sp., and a couple of leaf beetles. There was also another type of oak there – Arizona white, I believe, which I beat as well but only got one clerid.

It was a fantastic seven days in the field with Arthur, and it was a great pleasure to (in some cases, finally) meet Margarethe, Barbara, Steven, Norm, and Pat. I appreciate the warmth, generosity, and hospitality that all of them displayed to me and look forward to our next encounter, hopefully in the near future. Now, for some light reading during the plane ride home!
