Mydaea corni

Description

Mydaea is a genus of Muscidae flies characterised by having wing bristles on both dorsal and ventral surfaces at the radio-cubital node. There are 13 UK species but so far only three have been found in Leicestershire and Rutland. Mydaea corni is the commonest of these. The red legs and scutellum together with the reddish yellow abdomen help to distinguish this species from others in the genus.
