Here's another one. It has a little bit of blue on the edges of the hind wings. Owen

What colour were the uppersides of that butterfly? The only alternative to mazarine is little blue (which can be surprisingly big in the mountains). That is a male. If the ups were dark it is little blue. If the ups were blue it is mazarine. It is (almost certainly) not Osiris.

I think it was blue. It was my first day and I had found this incredible meadow alive with butterflies and I was unable to slow down and acually study what was there. Instead I took loads of rubbish photos which were very difficult to sort out later.

That appears to be a female common blue. I can't separate female common blue from female Chapman's from the upperside alone, but the underside you showed on the last page was that of a common blue.

EDIT: That reply was in answer to the first post on this page. In answer to the second(which seemed to cross in the post) , I think that confirms mazarine blue.
