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!

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.
