A small Pollenia (6 mm) should be P griseotomentosa.

 The facial carina seems to be present as does the outer posthumeral bristle (if my eyes don't deceive me). To continue we'd need images of the legs (tibiae and hind femora).

 Thanks for the input Eric !

Lets see if these images can help.
Which one should be the outer posthumeral bristle ?

 Thanks for the excellent images! Perhaps they are too good for me: the more I look at the humeral bristles on the 3 photos the less I'm sure.
I'll try another approach:
Do you agree, that the mid tibia shows 2 ad bristles? (left_mid_tibia.jpg)
Palps are black? (pg_face.jpg) - excludes P. viatica
Femur 3 shows no yellow hairs? (left_hind_femur.jpg) - excludes P. angustigena
If so, it's probably P. rudis.

I used the key in Olga Sivell (2021): Blow flies

 I agree completely.

I got stuck on the 2 marginal bristles on scutellum which would lead to griseotomentosa but I suppose the smaller one (red arrow) also should count.
In that case everything fits with a female rudis.

Thanks for helping me out Smile
