I think Hilara for the shape of the antennae and for the thin blackened spot on the outer edge of the wing. If it is Hilara, can we go to the species? Thank you for your help.

Identifying southern French females of Empis s.str. from will always be a challenge (and one we will most often loose). Paul - - - - Paul Beuk on https://diptera.info
