Life Cycle
Larvae are parasitoids of solitary bees. Female follows bee from flower to nest, then lays egg in entrance tunnel. (Females are also seen hovering over open, sandy, ground, and they are presumably looking for nests.) Fly larvae feed on the larvae of the bees, pupate in the bee nest, and emerge in spring or early summer. Hosts include Andrena, Colletes, Halictus. What are apparently males have been seen to hover in display in North Carolina. These males were dispersed several meters apart in a deciduous forest habitat. (P. Coin, personal observation)
