Mites in this family are responsible for producing galls and dense patches of hair or beadlike growth called erinea on a number of plants. Several commonly seen galls are: maple spindle gall, maple bladder gall, and erineum on maple. The size of the mites is less than 0.5 mm.
Treatment is not usually not necessary, as lasting harm to plants rarely occurs.
