I think it's a female of Limnophora obsignata (Muscidae).

I'll add : typical pattern on thorax (see "Faune de France - Dipt?res Antomyides", E. Seguy), two patches before suture, one broad transverse band beyond suture. Abdomen with typical pattern of Limnophora (ie with large dark triangular spots), and apex of M1+2, not strongly, but conspicuously upcurved near tip.

Anthomyia illocata does not occur (so far) on the European mainland. The white area on the scutellum is not the right shape. I have forgotten what the similar muscids look like, but they certainly can fool one.

A. illocata is mainly an Asian species, but recently has been found spreading in America arouond Florida, so anything is possible

A quick look under the microscope at the chaetotaxy would show the difference.
