Found a key in Hedström (1995) for the Nordic species, and think this is S. bicolor based on the small but dense hairs on scutum, but see the comment on the next picture with the costal spines. The specimen is btw ca 5,5 mm.

Though, the costal spines is maybe too long, as they should be ca as long as width of costa. In S. mikii (which Hedström says also can have spread hairs on scutum) he gives the spines as 2-3 as long as width of costa.

Morgan Amundsen made me realize that I have misread the key, switching scutum with scutellum... This fly has no (small) hairs on scutellum (the specimen checked again this evening), and thus keys out to S. mikii.

Suillia dumicola Collin, seems to be rather close to S. mikii. No idea if this species could also be present in Norway.
