Conopid flies are endoparasitoids of adult Hymenopterans but the distribution and ecological limitations of the 67 species that occur in the United States are mostly unknown. Bumble bees (Hymenoptera: Bombus) were collected across an urban to rural gradient in Madison, WI during summer 2019 and analyzed for the presence of conopid fly larvae. Bees were captured, dissected, and microscopically inspected for the presence of Conopid larvae. We compared the percent parasitism (prevalence) and distribution of Conopid flies from areas of high urbanization to low urbanization using landscape indices of Madison, WI. Further, we used host functional trait data to predict host species selection by conopid flies across sites. Results from this research will contribute to our limited understanding of Conopid fly ecology and bumble bee parasitism in a region that is home to one of the few large extant populations of the endangered Rusty Patched Bumble Bee (Bombus affinis).
