Hi Paul,

I'm not sure 100%.
It could be also a form of Hedychridium caputaureum, for the evident golden-green face and posterior margin of pronotum.

Ciao!

Hi folks, nearly four years have passed since I saw the species that is shown on the pictures the last time before I could meet some specimen this season in my home area. Yesterday I was happy to see this species also in a new area. Let's see what the future will bring. This area seems to be very pr...
