This hairy mimic of a bumblebee is in fact only a hoverfly - Volucella bombylans. A large hoverfly, it has bee-like, large, hairy legs
and orange and white hair. Left above is a male with big eyes close together on the top of his head; right above, nectaring on knapweed,
is a female with eyes separated on top of her head.
To mimic different bumblebee species for protection, Volucella bombylans var. plumata
above with plumed antennae has a white tail and var. bombylans is black with a red tail.
Applause!
The large size and black markings on the wings help to distinguish this fly from other bee mimics such as the Greater Bulb Fly.
The larvae live in nests of bumblebees or social wasps, eating waste and possibly some bee larvae.
