Aceria fraxini (
Garman, 1883)
|
Aceria fraxini, the ash bead gall mite, is a species of mites in the family Eriophyidae, the gall mites. [1] [2]
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
