Bembex

Bembex (i.e. 'whirl'), a genus of solitary sand-wasps (Sphegidæ), represented by numerous species in most parts of the world. They are roughly wasp-like in appearance, with broad heads and very large eyes, and make a loud buzz during their rapid flight. The female bembex burrows a hole in the sand, and there deposits her eggs, but before closing it up collects a store of flies, on which the larvæ at first subsist. See WASP.
