Grison's Fritillary is a rare and local mountain species which is endemic to Europe. The male's upperside is bright orange with thin regular markings. There is a dumbbell-shaped mark on the forewing hind edge. Its markings are very variable.

It is restricted to the Alps from SE France to Austria, and the Apennines in Italy.

It breeds in subalpine and alpine meadows, sheltered mountain slopes and hollows, usually above 1500m.

There is one brood between late June and late August.

Larvae feed on Plantago alpina and Gentiana species.
