Indeed, the very dense punctation on the second tergum caught my attention. The viridulagroup seems quite diversificated in the south of France, there is probably other species to find !
Hi Thibault, yes, they are enough for ID. It's a male of Chrysis daphnis . And the previous one is a female of Chrysis consanguinea . You can compare the punctation of their abdomen. In Chrysis daphnis punctures are small and dense on the second tergum. ...
... he's very smaller and differentely coloured than my males of viridula (especially the first tergite redder), maybe it can be the male of Chrysis consanguinea ? If the picture of genitalias isn't sufficient I will be able to take ...
Hi Thibault, well, the first evaluation is on the cuckoo wasp size. Chrysis vareana is really large, similarly to C. integra (or a bit smaller), ... bulky (less slender) that the latter. It really looks like a giant C.viridula . Then colour pattern: the female frons (seen in dorsal view) is ...
... a sandy floor near to tubes of solitary Vespidae . I think it could be Chrysis consanguinea for the very elongated shape and the golden spots between the eyes, but I don't have experience in the viridula group, except for viridula itself.
