Asilidae - Robber Fly

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 notoriously aggressive predatory habits; they feed mainly or exclusively on other insects and as a rule they wait in ambush and catch their prey in flight.

I have been restoring some of my property to native prairie plants and was excited to see these top level predators. It is a good indicator of how healthy the ecosystem is. Two of the photos show a fly that has captured a wasp, one photo is of them mating. Click on the photo for a better view.
