In France, the Luberon area, I found a lot of Spotted Fritillaries (Melitaea didyma) but noticed that some of them were different; on the upperside they had lesser spots/dots but on the hindwing they had obvious black spots.
On the left (the more brownish butterfly) is the regular Spotted Fritillary with a lot of spots, on the right (the more orange butterfly) is the not regular Spotted Fritillary with lesser spots.
An other Spotted Fritillary with lesser spots but with obvious black spots on the hindwing. During my two weeks visit I found three copula's of the Spotted Fritillary without a mix (they were al spotted).
The underside of the wing looks also a bit different. About 20% of the Spotted Fritillaries which I found had some characteristics of the trivia species. In my books and on the internet some identification marks are mentioned, like a discocellular vein but this vein was missing on photos which I found. A russian website with a lot of information and photos gave the decisive answer that these provence butterflies are not trivia's. The most obvious difference are the dubble black stripes/spots on the inner side of the orange band on the wing.
I'm not an expert nor a researcher but, also to the fact that I found three copula's with only the spotted Spotted Fritillary, I have the feeling that there is maybe an other subspecies: the didymaeformia trivia?
