Bootanomyia
Bootanomyia is a genus of parasitoid wasps in the family Megastigmidae. Members are small chalcidoid wasps that develop as parasitoids within oak galls induced by cynipid gall wasps. Two European species morphologically keyed to B. dorsalis have been introduced to North America: one clade found in New York, and another in the Pacific Northwest. These introductions represent the first documented cases of Bootanomyia establishment in North America.
