Facts: Robber flies are very common insects especially in the summer. They are active predators that catch insects on the wing. They often sit on a conspicuous perch and fly out to catch insects passing by. A few of the robber flies mimic bumblebees and are very difficult to distinguish without a close inspection. Of course, they have only two wings like all flies while bumble bees have four wings. Robber flies also have a concave area on the top of the head between the eyes.
