Description

Wing span: 50 - 60mm

A large butterfly which shows a significant amount of sexual dimorphism. The males are very dark, with two white-pupilled ocelli on each forewing. The females show a more typical combination of greys and browns, with some orange on the forewing.

It is widespread and locally common in southern Europe from the central Pyrenees to the south Balkans. More sporadic in its western range and in Italy.

It is found in dry, warm and grassy clearings in woods, bushy and rocky edges of oak forests, rough hillsides and rocky mountain slopes mostly between 500 and 1800m.

There is one generation per year from early June to late August.

The larvae feed on fescues and other grasses.
