Scathophaga furcata
Tends to be a stout species with a dark marking on the outer side of the front femora (similar to S. lutaria which has a plumose arista). Legs entirely yellow, apart from the dark mark on the front femora. Wing length: ♂ 4.3 - 6.0 - 7.5 mm (61); ♀ 5.0 - 5.9 - 7.5 mm (49).
A very common dung breeding species often associated with sheep dung and tending to replace S. stercoraria in more upland localities, although the two frequently occur together. Recorded from dog, human and sheep dung and frequently from privies (Skidmore in Stubbs & Chandler, 1978[1]).
