Heleomyzidae
Heleomyzidae are small to medium-sized flies which vary in colour from yellow to reddish yellow or reddish brown to black. The wings often have small but distinctly longer, well-spaced spines mixed with the shorter spines along the leading edge and the crossveins are often clouded.
Adults of Borboroides and Heleomicra are attracted to carcasses and faeces. The larvae of the Holarctic Suillinae and Tapeigaster occur principally in fungi. Larvae of Cairnsimyia live in borer tunnels in trees. __NOTOC__
