Bombylius major
The Large Bee-fly, ''Bombylius major'', is a bee mimic. The eggs are flicked by the adult female toward the entrance of the underground nests of solitary bees and wasps. After hatching, the larvae find their way into the nests to feed on the grubs.
''Bombylius major'' can be found in April to June throughout temperate Europe and North America and some parts of Asia.
==Description==
The adult is in length, squat and very hairy, with a wingspan of around . It has dark patches on the anterior half of the wings and long hairy legs that dangle while in flight. The very long proboscis is used to feed on the nectar of many species of flower, especially primroses. While its wings continue to beat its front legs grip the flower and its long rigid beak is inserted to collect the nectar.〔''Insects'' , Collins Gem , Guide, 1986, page 114, ISBN 0004588185〕 Despite its fearsome appearance, the beak is quite harmless.〔
Bearing a mimetic resemblance to bees their body is stout and furry, with the top of the thorax being black and shiny and the pile either brown, yellow, or white. They have long spindly legs as well as a long rigid proboscis found in the front of the head. Their boldly patterned wings have a distinct dividing border through the horizontal middle between the dark and clear portions. Their antennae are typically very short and pointed. In the field they will be seen hovering and darting above bare ground or flowers, in an up-and-down movement, accompanied by a high-pitched buzz.
