Ash Flower Gall Mite
Aceria fraxiniflora
Aceria fraxiniflora, the ash flower gall mite, is a species of gall mite that produces galls on ash trees. The male flowers of ash are greatly distorted by the mites, which results in a highly disfigured and disorganized gall that remains yellow or green, and later dries and turns brown. However, there is little evidence that this injury has a substantial impact on the ash plant's health.

In human culture
Several generations of mites occur during the spring and summer season. During spring, female mites that have survived winter move toward developing male flowers to feed, which leads to the formation of galls. The eggs of the mites are deposited in the developing galls, and the nymphs that hatch out of these eggs live and feed inside the gall tissue. In fall, a generation of female mites develops, which overwinters in bark crevices under bud scales, after mating.
