Ecology
Range is North America, including southern Canada and most of the continental United States.[2]
Mites form numerous capsule galls, greenish-yellow in color, between leaf veins of ash trees in the genus Fraxinus, including Fraxinus americana, Fraxinus latifolia, Fraxinus nigra, and Fraxinus pennsylvanica.[3][4] The mites stay in the galls until late summer when host leaves mature.[5]: 50
The life cycle is a form of alternation of generations. An over-wintering generation consists only of females called deutogynes. The other generation consists of both sexes: females called protogynes as well as males.[5]: 6
