Aceria genistae
The mite Aceria genistae causes galls to form on the buds of Broom (Cytisus scoparius). The galls take the form of an irregular mass, 5 to 40mm across, formed of miniature distorted leaves covered with greyish pubescence. These galls conceal and nourish the mites. The galls are seen more often than the mites.
