A striped fly with spotted wings observed on hawthorn and other bushes in a garden in France
No identification made yet.
No interactions present.
There are other sites you could try for this one, if none of the experts here have commented.
Diptera.info would be the best to try, probably.
But this site is French, and also very good.
