Deception is everywhere in nature. Animals and plants routinely cheat, lie and manipulate for their own benefit. One example is mimicry, where one species (the mimic) has evolved to resemble another (the model).

No group of animals takes this to greater lengths than hoverflies – bean-sized bullets that zip around your garden, cosplaying bees and wasps.

As some new research by ourselves and others show, hoverflies surprise not just their predators, but evolutionary biologists too.

Mimicry is most often for protection. Harmless mimics evade predators by evolving to resemble dangerous species. Some can even mimic several species. But mimicry can also be aggressive, where dangerous species dress up as innocuous ones to ambush unsuspecting prey, like the spider-tailed viper – or to steal food, like the rove beetle with a fake termite on its back.

It can be sexual. Flowers such as bee orchids resemble female insects to trick males into trying to copulate with them, unwittingly pollinating them in the process. Weedy male bluegill sunfish adopt the dark colouration of females to sneak into the brightly coloured alpha male’s harem and mate with........
