July 20, 2006, collected by sweeping.
Size around 4mm.
Maybe someone is familiar with it, for colour pattern looks quite characteristic.

Hi Dima,
Very nice specimen! It looks like Braconidae to me. I will ask around.

Definitely a braconid wasp (from the wing venation) - and a lovely photo :) Perhaps Kees van Achterberg would be able to put a name on it - if anyone has his email?

Yeah - Kees van Achterberg is literally "the man that wrote the book on braconid wasps" ... in fact quite a few books! :D

Hi
How can we distinguish between a Braconidae and Ichenumonidae in the field?? I thought, at first, that this was an Ichenumonidae wasp... thank you!!!

Just received a response from Kees van Achterberg:
Looks like a member of the Alysiini. If so, it would be Trachyusa aurora. Very nice pictures indeed!
So it probably is
Trachyusa aurora (Braconidae: Alysiinae: Alysiini).

I do not use any document, each one his speciality and I ask Kees quite simply! ?
?On the ground, the practice puts to me on the track but it is necessary to see the nervation of the wing and the second discoidale not closed to recognize Braconidae! ?

Well Camille (if I may), I think it's great to be able to ask for an opinion of such an expert directly :)!

I asked Kees van Achterberg for information on the biology of
Trachyusa aurora. Kees told me that
T. aurora is recorded as a parasite of
Trichiosoma (Trichiosoma) sorbi [Hymenoptera: Symphyta: Cimbicidae]. However Kees told me that this record is not correct! So the biology is still unknown.
That the record is incorrect is not surprising since Alysiinae are known as endoparasites of cyclorrhaphous Diptera. So Dima, also this hymenopteran found a good forum to be posted upon:D.

Hello
Is Trachyusa aurora present in France, in Fauna Europae no data for France .
Thank you
Louis

Hi Louis,
The data on Braconidae for the Fauna Europaea project were entered by Kees van Achterberg. So since
Trachyusa aurora is not recorded as present in France, Kees has seen no records of this species from France. However since this species is known from Spain, Italy, Switzerland, Germany, England, and The Netherlands (a.o.), there is a good chance that it will also occur in France! So keep looking for it and if you find it, notify Kees van Achterberg;).
