Dioctria atricapilla is a species of robber fly in the subfamily Dasypogoninae, found in grassy environs throughout Eurasia. Measuring 9–12 millimetres (0.35–0.47 in) in length, with a 7–9 mm (0.28–0.35 in) wingspan, it feeds mainly on smaller flies and predatory hymenopterans.

Hyperechia nigrita
…is a species of robber fly (Asilidae) that occurs throughout Central Africa. Like other robber flies this species is a mimic of bees, with it sporting a coloration similar to Carpenter bees of the genus Xylocopa. It likely uses this coloration to allow its self to get closer to its prey, which most likely consists mainly of bees and other insects, which are taken in flight.

Mallophora bomboides is a bumble bee mimic robber fly.  This example was  photographed at Archbold Biological Station; the robber fly was hanging  near a mixed patch of liatris and golden rod.  I did not see this one  make a capture but, having seen others at work, it is amazing how  quickly these ungainly looking insects can launch themselves after prey  insects (primarily pollinators).
