Mountain Argus

[David Tipping]

Here's another one from the Spanish Pyrenees. It was seen at high altitude and I had it marked down as mountain argus, but there are two additional spots on the upper wing (arrowed), which shouldn't be there if my identification is correct. Any ideas?

Hi David. The only options are common blue and Eros blue (females). I would unhesitatingly go for common blue on appearance alone, as it doesn't look anything like female eros from the Alps. But I can't recall seeing female eros in the Pyrenees and I guess it might be closer to icarus ...

Nevertheless, I'd go for common.
