I think it should be a male
Anthomyia pluvialis. Right?
Because I found:
Anthomyia pluvialis is very similar to A. imbrida and A. procellaris. Male pluvialis can be distinguished by the dark mark at the base of the wings being divided into two separate spots. In males of procellaris and imbrida this is fused into one connected spot.
