Robberflies (Asilidae)

by Jeffrey S. Pippen | Back to Jeff's Miscellaneous Invertebrates Page | Jeff's Nature Pages

The Robberflies (Asilidae) comprise a large and diverse family of flies (order Diptera). Robberflies are predatory on other insects, and although they look really mean and occasionally land on people, they rarely bite if left un-hassled. When they land on you, they're only looking for a ride -- and they might even launch off you to chase down and eat the pesky deerfly that's stalking you, so let 'em ride!
