Introduction
Robber flies are large, bristly flies that catch their prey (usually other insects) mid-flight.
Habitat
Robber flies live in urban areas, forests and woodlands.
Distribution
Robber flies throughout Australia. Because of their size and active habits, robber flies are one of the more common flies seen in Sydney.
Feeding and diet
Each leg of the robber fly has a pair of strong claws to catch their prey before injecting a powerful poison. Enzymes help to digest the meal and all that remains is the discarded exoskeleton (external skeleton).
