hello other insectsforum,
This typical insect must be some kind of wasp I think.
It is a beautiful tiny 'wasp', gold-coloured with red eyes.
The shape of the wing and the drawing lines inside are characteristic I think..
When I look at the big eyes and the antenne I should say 'wasp'
What do you think? And what kind of tiny wasp is this?

It's a wasp, Chalcoidea, possibly family Torymidae. But even for a specialist it would be hard to determine to species without the animal.

Thank you J?rgen,
Nice to know about the existence of that group of wasps anyway!

Definitely a chalcid wasp ... reminds me of a pteromalid, but then again, so many wasps remind me of pteromalids! :D

Still a thorny subject in prospect! :D

Le chalcidien sur un organe v?g?tal beige est un Pteromalidae Pteromalinae du genre Pteromalus, Sous-genre Habrocytus Thomson. Il s?agit d?une esp?ce du groupe de Pteromalus elevatus (Walker), peut-?tre m?me cette esp?ce. Il y a plusieurs esp?ces tr?s difficiles ? distinguer dans ce groupe. Parasitoide de dipt?res Tephrytidae sur Asteraceae. S?observent souvent sur les chardons.

Thanks a lot for your reaction!
It is a rather difficult subject (little wasps...)
I tried to translate it, but I can say.., it is really difficult for me (two years french on school)..
I understand that this wasp is a wasp from the pteromalidae sp. (in the netherlands about 395 sp.) and it could be a wasp like Habrocytus Thomson (is this the same as Habritys Thomson, 1878??) But it could be also a wasp like Pteromalus elevatus (Walker, 1834)??
These are wasps which parasite on Tephrytidae flies, you can find them also on thistles.

I think it says (from my rough french) that it is from the family Pteromalidae, genus Pteromalus
Thomson. It is in the Pteromalus elevatus
(Walker) species group, and maybe that species exactly. But the group contains many species and it is difficult to distinguish them. A parasitoid of Tephrytidae on Asteraceae. :)
