Muscid? With flattened hind femora

I suspect that the flattened hind femora indicate that the fly is recently emerged and the cuticle has not hardened sufficiently for the legs to retain their shape. We probably need better photos to say more.

Thanks Tony, I will try to improve my photography technique! I am pretty new to Diptera, although similar results occur in “teneral” Coleoptera.
