Identifying features
Wingspan 35–43 millimetres. On the upper side, the wings are brownish-yellow with black markings; the underside has a silver-white toothed band. The triangular white edging distinguishes it from Arctic Fritillary.
Similar species
May be confused with Arctic Fritillary (Boloria polaris); Purplish Fritillary has triangular, rather than T-shaped, white spots along the wing margin.
Distribution
Found only in Sweden, Padjelanta, Torneträsk, and Pältsan; otherwise circumpolar in Arctic.
Biology
The development is poorly known; the Swedish tourism growth is likely to be limited to the edges of the forest.
