Illinois Status: common, native
Features and Behaviors
FEATURES
Also known as the white face fly, this species is about 0.40 to 0.60 inches in length. Its head and thorax are much lighter in color than the dark, shiny abdomen. There are large bristles on the body.
BEHAVIORS
The adults eat flower nectar and act as pollinators. The female lays her eggs on forest tent caterpillars (Malacosoma disstria), fall webworms (Hyphantria cunea), corn earworms (Helicoverpa zea) and cutworms. The egg hatches to a larva that burrows into the living moth larva, eating it and eventually killing it.
