My guess: Eutrichota

I have doubt about Eutrichota....
Large crossvein is straight (is in Eutrichota with a bend)
Only 2 orbitals (more in Eutrichota)
On hindfemur some scattered long av / pv (in Eutrichota mostly row of av / pv)
Midfemur seems to have no long av / pv....
I am almost thinking about Pegomya seitenstettensis again... (you must have also the male on photo somewhere)

But......with 3pd on t3......, could not find any mention about the female in Hennig or Ackland, about the possibility of 3pd
But as Nikita told me......a key is not a bible you have to stick to!
I personally say: Pegomya cf. seitenstettensis female
(but still with some daubt!)

I based on very long and outward directed pra seta only.
I do not insist on Eutrichota, but I'd like to know the answer. We can ask Michael...

Of course.....curious myself also!

I have seen about a dozen male P. seitenstettensis this year.

Joke, the fly is in my freezer, if it is a special one it will be yours ;)

Answer from Ackland:

I am probably as baffled as you all are! It is not Pegomya seitenstettensis female (although this species has a very long pra). The latter character points to Eutrichota, but it is not like ay European species I have in my collection. The blackish thorax points to something in the E. socculata region, but I know of no species in this group with yellowish hind femur with a distinct black apical part. Whether it is an abnormal female as far as colour of legs are concerned it is difficult to say. Can't see the aristal hairing or the nature of the cruciate setae on frons, or even if they are absent as is tthe case for Eurtrichota.
Norway may still provide some unknown species?

I asked him about the straight crossvein (what is with a strong bend in Eutrichota)
Answer from Ackland:

The straight crossvein is a puzzle.
I am still searching through my collection for a female which has such distinctive hind femur, with the basal two-thirds orange yellow, and the apex with a black ring. I only know this from some oriental Pegomya's.

So.....Hakon if possible collect several male !!

This is great :D

It will probably rain for a week here, but next weekend they promise sun.
Maybe I will get lucky and find more, including males.

Let me know if you want more crops.
