I think that female M. osiris is only photo N5

Thank you Nikita, for your constructive critique!
My photos of the female are from July 7th and belong to 2 sessions:
First (including image 5 and 6) from 11:31:14 to 11:33:52 - pretty sure, that it's the same fly female
Musca osiris. If you compare the dc-bristles on these 2 images you will find the same pattern.
Second (including 3, 4, 7) from 15:09:26 to 15:10:53. When checking it again intensively, I think this female is a small
Musca autumnalis (abdomen is not uniformly grey and all 4 dcs are distinct.
The hairy eyes of the very lively
M. osiris female are hard to see on a photo - especially if it's stormy, but on #5 the pilosity is visible.
I have modified title and subtitles of this thread accordingly.

Eric, I have very limited skills in Musca, well may be that I'm wrong.
However, photo 5 has shining scutum and it seems to me that there are short and sparse hairs on the eyes.

Nice understatement, Nikita, the limited skills! ;) who wrote "DIPTERA an Introduction to Flies"?
But kidding aside: yes, I see the shining scutum and the short and sparse hairs on the eyes.
And it is the same fly as #6, which is in the shade and shows bristles on scutum and the more shiny grey abdomen - similar to the fly from the Azores in GBIF.
