Thanks again,

Hello Simon, this is a female of Melanargia larissa then. For Melanargie the underside is more important than the upperside. This butterfly genus usually sits on flowers with closed wings. When another individual flies by it will only see the underside, therefore the underside has the most evolutionary pressure and will look more different.
I checked the book by G. C. Bozano and my personal Melanargia collection.

Ok I drew a picture to get my point across. Every butterfly species has the same wing pattern elements. One of them is called the central symmetry system. I drew this system for 4 species, they look very different when compared to each other. In some species the symmetry system is colored inside, in others ( M. occitanica)) it has only an outer line (also known as Media I and Media II). Using this you can identify your specimen even tough the dorsal color elements may change and look odd.  |

Claude, Many thanks again for your assistance and for going to the trouble of producing these excellent images!  Simon |
