Dear all;
Enclosed fly is waiting since days in front of my Bombus pratorum nest to enter. Entry is not possible as the nest is protected with a mechanical door.
Can someone say anything about ID? Is this a parasite or just a Kommensale..
Size ~5-7mm; found last week in Upper Austria ~300moS
Thanks for help;
Norbert.

No one who can support?
Checking the gallery I would say a Muscidae; maybe Phaonia; or Thricops?
The fact that larvas obviously live in Hymenoptera nest should also help.
Thanks for any hint;
Norbert.

It is female of
Fannia lustrator, Fanniidae.
F.lustrator larvae reported either from rotting plant material and from nests of social Hymenoptera (Vespa crabro & Vespula sp.). Nice observation! Keep observe, F.lustrator regards as commensal, not parasite, but nobody is sure as, I suppose, you are the first person who observes the process itself.

many thanks for this info. I have a nest of Bombus hortorum which I am observing under lab conditions. If the fly is still there this afternoon I will put it into the nest and see what it does..
best regards;
Norbert.
