Golden Dung Flies - Scathophaga stercoraria - Male Female
Mineral County, West Virginia, USA

These seem to be very actively mating in October, but I know little of their habits otherwise. I notice that the other photos of them on here are from West Virginia. Do these appear elsewhere?

Just follow the smell...
If Scathophaga stercoraria flies in America are just like their conspecifics in Europe, you will be able to find them everywhere where you find cow dung. They are major inhabitants (or rather their larvae) of cow pads and fierce predators on anything else that tries to live there. Some rove beetles (Aleocharinae) again predate/parasitize their pupae.

The flies are relatively insensitive to cold so you can find them throughout the year as long as the temperature does not get too low.


Thanks, Paul.
These creatures have been here for years then, throughout most of the year, and I haven't known it. There is much to discover in our own backyard.
