Unlike an actual hornet, the robberfly only has one yellow patch on its abdomen and one pair of wings. The larvae are believed to feed on dung beetle larvae and other detritivores. It is a member of the robberfly family Asilidae, subfamily Asilinae and is included in the list of endangered species in the British Isles.
