Hello Rosevinge, your photos are always very nice :) problem with Musca is that autumnalis and domestica are not the only options. Musca larvipara is difficult to separate from autumnalis. If you have Musca larvipara in your area, then this is a problem. Otherwise, it is probably Musca autumnalis.

I had a lengthy discussion about this with Stephane:
