So, where did you find it (habitat ?).

As far as I am aware, genuine trompe always have a transversal band of black hairs on abdomen. This would be a candidate C. stimulator.

Thank you Theo, I found this about 520 meters above sea, in a valley with peat, was some trees around were i found it, but most of the area are treeless dominated by peat.

It proofs nothing, but it fitd better to stimulator (host: Capreolus) than trompe ( reindeer).

There is alot of reindeer in the area tho, its a place where alot of tame reindeers have their feeding ground. Is there any other morphological details that could make us sure?

Grunin in Lindner says
"*Vertical keel on facial shield (below the antenna) normally absent. Tergites 3-5 without any black hairs along the central axis --> stimulator.
* Vertical keel on facial shield present. Tergites 3-5 along central axis with a narrow zone of black hairs. -> trompe (and ulrichi)."

In his description of trompe he states

"Tergites largely with dirty-yellow hairs. At sides of tergites 2 and 3 a large spot of black hairs. Along the central axis of tergites 3-5 a very narrow bend of black hairs, which can be difficult to see."

I also can't see any dark hairs at all on abdomen. So I guess most of this points to stimulator. The species doesen't seem to be registered from Norway before tho.

I am sorry, I took your word for it that it was a Cephenemyia. But looking at the wing venation, this strongly suggests this is the male of Hypoderma tarandi !
Could you provide a better view on the venation ?

Yeap, that is Hypoderma (tarandi). That solves the mystery !

Reindeer, after all.
