Stenopogoninae
Stenopogon sabaudus
The Asilidae are the robber fly family, also called assassin flies. They are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking hypopharynx. The name "robber flies" reflects their expert predatory habits; they feed mainly or exclusively on other insects and, as a rule, they wait in ambush and catch their prey in flight.
Asilidae
Zosteria sp.
A member of the Asilidae feeding on a grasshopper. This asilid shows the mystax and ocular fringe typical of the Asilidae, with short, stout proboscis and spiny, powerful legs, adapted to the capture of prey in flight.
Choerades fimbriata: a powerful predator with body adapted to fast flight. Note the mystax, the proboscis and the depression between the eyes.
