Overview

Boloria aquilonaris, the cranberry fritillary, is a butterfly of the family Nymphalidae. It is found in northern and central Europe.

The Cranberry Fritillary faces significant threats from habitat loss and degradation of its specialized bog and wetland environments due to drainage, peat extraction, and agricultural conversion. Climate change poses additional risks by altering the hydrology and plant communities of these sensitive ecosystems, while the species' dependence on specific host plants makes it particularly vulnerable to environmental changes.

Threat summary

Habitat

Inhabits acidic bogs, fens, and wet moorlands with abundant cranberry plants and other ericaceous vegetation. Requires open to semi-open wetland habitats with specific moisture regimes and host plants including bog cranberry and cloudberry.
