The photo is very dark but it appears to be a Musca male. The frons is too narrow to be Musca domestica, so we are facing autumnalis or larvipara.

You are very knowledgeable, so it should be a Musca. Genitalia doesn't help here because it isn't usually depicted in keys. However, the supra alar ridge and the cheeks can help. You can read identification info from Stephane in my post:

Hello Mihailo,

I am sorry for the errors in my last post. I have a migraine today and i have trouble focusing or even thinking clearly. I meant to type suprasquamal ridge and gena. Linguistically translated as over-calypter ridge. If you move the wing for a better view of the calypters, then you look above the lower calypter (suprasquamal) and follow that ridge-like membrane to the scutellum. I find it easier to start where the scutellum meets the thorax, then follow that usually brownish-orange or amber colored membrane. The hairs will cover the length of this ridge for larvipara.

Hi John and Nini,
Thank you so much. Hairs on genae and supra alar ridge indicates that's Musca autumnalis male. I will save informations and photos from your post.
Best regards, Mihailo

Excellent! good job, my friend :)

I'm happy that my post has helped. Stephane is brilliant with Muscidae. I miss him in the forums. I hope that he returns again.

Job well done, Mihailo :)
