... the tarsi are dark so it is not Spintharina of course :doh: Great if it could be C. valesiana , obviously this one is different from the C. graelsii found the previous years at the same place. Though except the color, I couldn't find much infos about the differences...

simply ... no words ...


I have only two comments:

Congrats, beautiful pictures for beautiful species

should be Chrysis perezi (Chrysis valesiana ssp. perezi?), it's at least the graelsii-group

Ok, thank you for help : In his Faune de France, Berland & Bernard cited : France (Hérault, Var), Spain, Sicile, N. Africa. I have a male of graelsii group (like valesiana) of south of France (Aude), cought on wall (with many Eumeninae and some Megachilidae). I hesitated between graelsii, ...
