Re: Hedychrum ? - from Romania

Hi Cosmin,

Thanks for your pictures.
The mid-tibia is usefull only when you examine males.

Ciao
Paolo

Re: Hedychrum ? - from Romania

Hello everyone! I don't think it's H. gerstaeckeri . I think it's H. longicolle Abeille. This species is quite common in SE Europe till Bulgaria, and probably also in Romania. The main difference is given by the lenght and colour of the hairs, ...

Re: ? Hedychrum gerstaeckeri Chevrier, 1869, male

Hi Vladimir, It's very simple. By using the microscope, insert a pin (0, 00, 000) between the last tergite and last sternite and bring out the internal segments. Inside this "packet" you find the genital capsula. Remove it from the rest of the internal urites and glue it on a label. Don't ...

Re: ? Hedychrum gerstaeckeri Chevrier, 1869, male

Hi, Paolo.
I can take photo of the fossula through a microscope later, then go back to ID.
I never dissected the male genitalia of chrysidids and I do not know how to do it.
Best regards, Vladimir.

Could you dissect the male genitalia?

Thanks
