Anthrax is a genus of bombyliidflies, commonly known as "bee-flies" due to their resemblance to bees. Most are dull black flies, and are usually small to medium in size, 4–20 millimetres (0.2–0.8 in), and many species have striking wing patterns.[5]
Anthrax is a very large genus. While worldwide in distribution, most species are from the Palaearctic and Afrotropic regions. The genus includes species parasitic on tiger beetles – an unusual trait among the bee-flies. A. anthrax larvae parasitize bees. Many North American species parasitize solitary wasps.[6][7]
