Bee mimic
The hover-fly Volucella bombylans, male pictured above, uses Batesian Mimicry to imitate the Red-tailed Bumblebee Bombus Lapidarius. Batesian mimicry is where a palatable or harmless species has evolved to imitate the warning signals of a harmful or inedible species. In this instance a stinging bumblebee. It is named after the English naturalist and explorer Henry Walter Bates (1825-1892).
