Musca osiris and vitripennis have hairy eyes.
Musca tempestiva has a whole black abdomen.
Musca domestica (male) has a broader frons ans more elongated abdomen.
It is either M. autumnalis or M. larvipara (in your area) :
you must look at the suprasquamal ridge (the ridge along the mesonotum, just before the scutellum, hidden by the large calypters) : if hairy on the whole length, it is larvipara, otherwide autumnalis. The genal hairs distribution is different between both species too.
