@lintworm Please read the title. Zoo Tycooner FR says that is photographed in Spain. Hence, it's Iphiclides feisthamelii and not Iphiclides podalirius. Moreover, it's photographed in the full center of Spain: Madrid. So it's extremely far from the only place in Spain where I. podalirius flies (the Aran valley, the only place in the Spanish Pyrenees that is oriented to the French side of these mountains). Apart of that, you can tell appart the species without need of location as it have small but consistent differences, so if you look at this image you can't say that it's I. podalirius after the author asked which of the two species is.
Unless, of course, what do you mean is that you consider I. feisthamelii as a subspecies of I.podalirius (both taxonomic opinions are widely accepted), but then I think that would have been good to clarify that in your reply.
