Season
Spring to early summer
Food
Adult takes nectar. Larvae feed on the larvae and supplies of bees, particularly Andrena, Colletes, and Halictus
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.
