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?

greeting, robert

Hello, Robert!

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

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.

Hello cthirion,

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.

greeting robert,

I think it says (from my rough french) that it is from the family Pteromalidae, genus Pteromalus sub-genus Habrocytus 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. :)
