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 Smile 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! Grin

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 Smile!

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 uponGrin.
