Species with which Brown Argus (Aricia agestis) interacts

This is an odd-looking form, with the white spot enclosing a block mark. It does look a bit like the the Scottish version of the Northern Brown Argus (which doesn't usually have black in the spot), but as far as I understand it the English version of the Northern Black Argus, which is presumably the more likely to be near to this location, has less orange on the wings. So I think it must be 'the' Brown Argus, but an odd form.

There is a very similar one on the UKbutterflies site:

You are right about it matching the aberration on the UKbutterflies site. A little further research led me to the Natural History Museum website, specifically this page:

Which has a specimen that seems to match my butterfly, Aricia agestis ab. snelleni
