Robberflies are hanging thieves in the insect world. They are always ready to drop and go when a good-looking meal flies by.





Robber flies eat biting flies and other flying insects like bees, butterflies and wasps. This species likes bees and dragonflies best as well as biting flies. During the day, they literally hang from branches or objects near the ground with their front legs, waiting to ambush passing prey. They are fast and noisy fliers, giving chase to insects that are already in flight. When they overtake them, they grab them with their legs to stop them from escaping. Once captured, the robber fly will stop at a branch or leaf and use its stiff mouth to pierce the body of its victim and then suck out the victim's insides.

They make a loud whirring noise as they fly because they beat their wings so quickly. They may be mistaken for a bee or a wasp because of their size and the buzzing noise they create.

Robber flies come in a variety of species. The ones from the Diogmites genus have a few color variations and different striped markings on the abdomen per individuals.
