This is already relatively late in the French Alps (2200 m asl).
The fore tibia shows this is the genus Dilophus. The wings are clear, with a dark mark at the spot of the pterostigma. There are white hairs on the fore leg.

And on the mid and back legs :

Does this ring a bell for some of you?
Thanks in advance.
