Robber flies belong to the family Asilidae. This family includes some of the largest and most distinctive insects in the order Diptera. Like all true flies, robber flies have only 2 wings. Robber flies also have a distinctive hollow space between their 2 large compound eyes. This characteristic distinguishes robber flies from most other kinds of flies. (uky.edu)
