Hi to all,

Another beautiful chrysidid collected on a old dead branch on the ground (in 5.july.2011), only this male :( .
On the same branch collected some males of Crabronidae (I think), a possible host? Anyone interested in them (3 of them are available, in alcohol)?

A bigger photo here.

Is possible to say more? This was posted also here.

WOW and SuperWOW :shock:

Fantastic pictures!

I really would like to examine at least one male. Could you collect also some females?

This time I'm not sure about the ID.
There are not many species in Europe with this features.

The most common is Chrysis bicolor Lepeletier.
Then we have Chrysis illigeri Wesmael and Chrysis caspiensis Linsenmaier.

This specimen seems a mix of the tree species. Colour and genital capsula are more related with bicolor, thorax punctuation with illigeri and caspiensis, teeth of the propodeum with bicolor and caspiensis.

Basically nobody knows caspiensis, described by Linsenmaier on 2 specimens from Austria and Russia. This species has been always confused with bicolor.
I think that this could be a colour variation of helleni, but I have to compare it with the type (the genital capsula of the type is unfortunately broken).

I hope to meet you at Entomodena the next September, so we can examine this case.
Ciao
Paolo

Ciao Paolo,

As I'm very "lucky" on finding Chrysididae, this is the only one... at least for now.
I hope will reach again the place in ~2 weeks and will see what I can find.

I will be glad to know any way to be able to collect more Chrysididae, tried with yellow plates and no success until now... only in one case collected 3-4 specimens. I know that is a way to attract them with a bait but I don't know the recipe :) .

Also some more will come as I will prepare them... in the freezer.

Regarding Entomodena, september will be impossible for me because in 2 october I have the wedding. And also I think that in september will have to present my PhD thesys.

Will see how to do it so this can be examined by you... maybe will be luchy to find some more, in that case you will have ;) .

:thanks: :thanks: for all your help.

Hi Cosmin,

no, it is not very important.
It excludes definitively Chrysis illigeri, but the black spot on the S-II are very similar in caspiensis and bicolor.

The shape of the black spot is very important only to separate females of illigeri and bicolor.

Ciao and many thanks.
