Extract

In investigations on the life-history of the onion maggot at St. Jean, Que., in 1951, a few specimens of a dipterous predator were found in the rearing cages in the laboratory. They were feeding voraciously on the adults, destroying a colony of nearly 300 flies within two weeks.

Specimens were identified by Mr. A. R. Brooks, Systematic Entomology, Division of Entomology, Saskatoon, Sask., as Coenosia tigrina (F.). Mr. G. E. Shewell, Systematic Entomology, Division of Entomology, Ottawa, has stated that nothing is known in Canada about the life-history of this species, but that it is apparently well known as a predator in Europe and that B. M. Hobby has published a long list of species on which it preys, including many anthomyiids.
