Thanks for that image, Andy. I had trawled through my own but only have an underside shot, which doesn't really help a great deal.
Of course, what an image generally
can't do is give one an indication of size. However, when seen in the flesh, there is a huge difference between the tiny
morronensis and the unusually large
montensis.
This Spanish Argus colony is extremely isolated, and there seems to be no information regarding which form flies at this site. Given the prominent unf spots, I'm minded to think that it most resembles form
hesselbarthi, which would also explain the relatively extensive orange lunules, which are lacking in the nominate form.
I'll happily give you the site details, Guy, and when you visit you'll be able to see for yourself.
