Hello, I am unable to identify this specimen, seen on an onion flower in June 2015, Girona (Catalonia, Spain). I am not even sure if it is Chrysididae. About 8 mm long. Thank you!
Very beautiful pictures and a very interesting species.
This is Hedychrum rutilans viridiauratum Mocsáry and I personally do believe that it is a valid species. In Europe it is found in the Iberian peninsula.
