Hoverfly
===========
Although these brightly-coloured insects look like bees or wasps, they are in fact true flies and do not sting. Hoverflies are excellent examples of Batesian mimicry (named after H W Bates who first described it in 1862). They generally mimic bees and wasps – insects that sting and also taste unpleasant, so are avoided by predators. Drone-flies mimic honey bees, Volucella bombylans has several different forms mimicking bumblebees, while others species are very convincing wasp mimics.


Robberfly
===========
Robber flies are not to be trifled with. Capable of immobilizing bees, wasps and other insects larger than itself, robberflies catch their prey in mid air. As with other aerial predators, robberflies have excellent vision, characterized by two conspicuous compound eyes. The mouthparts of this family have been modified to a stabbing proboscis. Flies were revered by the ancient Egyptians who awarded a military honor in the form of a golden fly pendant.
