Thanks, I add some (bad) photos for the wing venation.
Vein M1 not curving forward and arista non plumose (if I see well) so not Calliphoridae.
Perhaps as you say Spilosoma or as for your post Muscidae of the Spilogona - Limnophora group but I don't know the features that must be seen.....and why not a female of Anthomyiidae ?
