Asphondylia bigeloviaebrassicoides

(Townsend, 1893)

bigeloviaebrassicoides is a of in the , first described by Townsend in 1893. Like other members of the Asphondylia, this species induces on tissue. The specific epithet suggests an association with plants in the genus Bigelowia and potentially Brassicaceae , though detailed host records remain limited. Gall midges in this genus are known for their highly specialized relationships with host plants and their ability to manipulate plant development to create protected feeding structures.
