Almost certain you are right, Eric. Scutal pattern is the same. Other characters needed to be 100% bicolor are: entirely yellow palpi, 3 equally long dorsal preapical setae on hind tibia, as in the attached photos

another photo of sternite V showing rounded processes without setae and rather shining, widely separated
These photos were taken through the eye-piece of a binocular microscope, and hand held; surprising they are viewable!

Thank you very much Michael for your work and help. Impressive pictures.
I met the fly again yesterday, and got another picture.
Maybe that can help to id the fly.
Best Regards Erik

Just to reactivate this thread.
As the palpi does not seem to be yellow, i presume this it not P. bicolor, or?
Best Regards Erik.

I don't think you can see the palpi , only the proboscis? I
have seen a few bicolor with darkened palpi, colour is not always reliable I am afraid. The only way to positively identify anthomyiids is to look at them under the microscope,or dissect the male genitalia. Pegomya is a very large genus, especially in Northern Fennoscandinavia.
