Hi,

Another day, another place and two other Chrysididae .
When collected I was sure that this two belong to the same species, same general colors, almost the same size but when preparing and specially when extracted... two species.

So, this one collected in 6.july.2011 in Romania (Oltenia), close to Drobeta Turnu-Severin on Daucus carota flower.

A bigger photo here.

Is possible to know more? Posted also here.

WOW

male of Chrysis taczanovskii Radoszkowski, 1876

Not a common species, even if it is more common in E-Europe.

It looks very similar to the other species (Chrysis marginata), but they belongs to 2 different species group.

The first visible external difference is given in the relative lenght of the flagellomeres. Compare the pictures and you'll see that F-I (first antennal flagellomere) and F-II have different lenght.

Chrysis marginata belongs to the Chrysis (Chrysis) comparata group, while Chrysis taczanovskii belongs to the taczanovskii group.
According to Linsenmaier the taczanovskii group belongs to a different subgenus Cornuchrysis, mainly based on the short F-I in males.

Ciao

also for this one

Incredible photographs! Just stunning.
I assume you use photo-stacking, but do you use a macro lens or do you strap the camera to a stereo microscope?

Hi Alexander,



The images are done with Canon 7D and Canon MP-E 65. Offcourse with the help of photostacking software (I have buyed HeliconFocus, as I preffer that to the others).

All my best,

Ah, the marvelous MP-E ofcourse..
makes me wish I had a Canon instead of a Nikon, hehe.

Cheers!
