Hello,
This fly is present in large numbers on a pond on which it moves quickly to the surface.
The Ephydridae family seems to be a good match. The binocular reveals the absence of silk on the third antennal segment, which normally excludes the species with the neighbouring habit Setacera micans.
Would you have an opinion on the genus, or even on a species?
Thanks for your help!
Thiery

To me, this looks like Ephydra flavipes, a widespread species in the Mediterranean region
