The Robber Flies are air hunter. They also known as an Assassin Fly and Bee Killer. They have piercing mouth-parts and strong legs which can catch prey on flight. They are medium to large size flies with large eyes and necked head. They are active predators on flying insects, unselective in prey species.

Robber Flies in the above pictures show the fly captured a Cockroach. As usual, the Robber Fly attacked from the back side of the prey. Their mouthparts are the triangular proboscis  which insert into prey and suck the juice. Robber flies prefer sunlit area to capture their prey.
