Overview

Boloria frigga, the Frigga fritillary, is a butterfly of the family Nymphalidae with a circumboreal distribution. It occurs in bogs and tundra in Northern Europe to the north of 60° N, very locally in more southern locations, as well as in the Urals, Siberia, Northern Mongolia, the Russian Far East, western parts of the United States and Canada.

Frigga's Fritillary faces severe population declines primarily due to habitat loss and fragmentation of its specialized bog and wetland ecosystems. Climate change poses an additional threat by altering the hydrology and plant communities of these sensitive habitats, while the species' limited dispersal ability makes it particularly vulnerable to local extinctions.
