Author 'Gilbair' (Id 234814 ) : I didn't know until the existence of the Proserpine whom this is the only copy I have ever seen. It seems to be part of the same sub species as the Apollo much more popular. As for the blue flower as it gathers, I totally ignores the name. Near Orgnac l'aven, in the Ardèche.
