B. Dung flies (SCATHOPHAGIDAE)

Dung flies are a small family of flies that often appear in huge numbers, especially on farmland. Their chief interest is animal dung by virtue of their having spent their larval stages in it.

Dung flies are found in the Northern Hemisphere (with only a few species found in the Southern Hemisphere). They have even been found in the Arctic tundra.

C. Yellow Dung Fly (Scathophaga stercoraria)

The Yellow Dung Fly is the gold-coloured fly you will often see on cowpats (and horsepats), which is where the fly will lay its eggs. They are mainly carnivorous, and will predate smaller insects, being especially good at catching blow-flies (which is a good thing, as blow-flies are harmful to livestock).

Adult male Yellow Dung Flies are bright yellow and very hairy. Female Yellow Dung Flies are smaller and tinged with green or brown.

The photographs here show a small collection of Yellow Dung Flies that had been attracted to the Cemetery when we were cleaning out one of the small ponds there (in early April 2022). The very strong smell of the vegetation that had been pulled out and temporarily placed in a blue litter tray beside the pond was no doubt irresistible to at least one individual who decided to come and set up shop there.
