I would like to know if I'm correct.
Date 6/6 and 7/6, location Southern part of The Netherlands,
Habitat: sandy hill with nests of several digger wasps (Lestica, Cerceris, Philanthus triangulum, small digger wasps like possible Lindenius, Crossocerus and other wasps like Smicromyrme rufipes).
The female H. nobile/niemelai was also spotted here. But I'm in doubt about the H. nobile/niemelai 'male'. It could also be another Hedychrum species.
I spotted several species of Chrysididae on the sandy hill, going in nesting cells. So possibly I'm confused
Kind regards,
Pietsje
