Yellow Dung-fly (Scathophaga stercoraria):  Theses are familiar, albeit not very popular flies. They swarm around cow dung in large numbers, and the golden-haired males are particularly conspicuous. They are very active flies, constantly mating, laying eggs, or making forays to catch other flies attracted to the dung. They are common and widespread in a variety of habitats, especially well-used pastures with woodland nearby.

A rather narrow-bodied fly; males are yellowish with yellow hairs, while females are less hairy and greyish-green. The antennae are black in both sexes. They predate on other flies and can be seen from April to October.
