Distribution & Flight: North Africa, much of Spain through France to southern Scandinavia and Greece. Absent from much of Italy. Single brooded from June to August.

Habitat & Behaviour: Flowery grassy places often amongst trees but also well above the tree line.

Variation: The subspecies centralhispaniae from central France and Spain is more brightly marked on the upperside.
