The false dewy ringlet is restricted to the Pyrenees, and flies even there only locally, on rough grassland above about 2000m with rocky outcrops. The butterflies above were all flying in a remote part of the Val d'Aran, in the Spanish Pyrenees.

The butterfly is very similar to the closely related dewy ringlet, which also flies in parts of the Pyrenees but principally in the Alps. It is easily separated from it by the lack of dark transverse bars on the upperside and more significantly on the underside of the forewing. The undersides are also relatively less well marked, though the female shown above has quite distinct banding there.
