The nearby from my house is one fantastic place on the Chrysididae. On this place is only one dry tree. And I watched on this tree 15 species of Chrysididae.
On this tree was watching Chrysis fasciata,fulgida,gracillima,graelssi,ignita,impressa,indigotea,iris,longula,marginata,mediadentata,mediata,
pseudobrevitarsis,solida and Trychrisis cyanea...This is fantastic tree.

Here are photos of some of them...

Ciao ;)

Hi,
fantastic!
I would like to have such a tree in my home area.
And, of course, you list some species which I really want to see some day, like C. iris, which is very rare in our region. By the way: great pictures!
All the best Paul

Hi Paul,
Thank you very much!
Yes, it is nice place. But I have worried, that this tree will soon fall.
The Ch.iris is very nice and rare species really. I am trying to find next very nice species Chrysis equestris. But I have not luck and I can not find this species...
Ciao

radians or austriaca group :

austriaca group : female withe genae vertical & parallel ; male with normal (cylindric) flagellomeres

radians group (= pustulosa in Linsenmaier 1959) : head convergent to the clypeus ; male with flagellomeres rounded bellow
+ many species (except hirsuta + some other species in south of Europe) : metanotum +/- angulate posteriorly. (view in profile).
hirsuta : black setae on metasoma, radians & trimaculata white setae)

Hi Lukas,
the last one could be C. inaequalis in my opinion.
But I don't know if there are similar species around in your region.
All the best Paul

Hi Lukas!

I'm sorry :doh:
I forgot to write that also this post is superb!

Yes,
I think that the first specimen is a male of Chrysura radians,
whereas the second is a female of Chrysis inaequalis.

Ciao!
