The Scotch Argus occurs, not surprisingly in Scotland, but also in a couple of places near the Lake District in England. It is one of a difficult genus of a number of similar species which generally occur in the mountains. There were hundreds of these in Glen Fionnlaidh, Scotland, during a particularly warm spell a couple of years ago, they were even settling on our tent.

The underside picture to the right is from the French alps. The species has a prominent silver band and chequered fringes which helps its identification.
