I found some chrysidid on old stone walls of houses. I seen no many species, only this small Chrysis. For me it is C. cortii Linsenmaier, 1951, and I seen always small digger wasps Miscophus sp (Crabronidae), but I seen too many spider wasps (Agenioideus cinctellus, apicalis and nubecula, Pompilidae) on the same walls too during the observations (nubecula is not observed in my region, only more in south, during holidays).
However, I have seen 0 chrysidid on cliffs, scree , rock outcrop (calcareous rock), even in the same village (Montron-le-château, France).
