Overview

Boloria freija, the Freija fritillary, is a butterfly of the family Nymphalidae with a circumboreal distribution. It occurs in bogs and tundra. Its range includes Northern Europe to the north of 60° N, occasionally more southern locations, the Urals, Siberia, the Russian Far East, mountains of northern Mongolia and Hokkaido, as well as North America, extending in the Rocky Mountains to 35° N.

Freija'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' dependence on specific host plants makes it particularly vulnerable to environmental changes.
