Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Siberian Brown butterfly faces severe population declines due to habitat loss from agricultural expansion and urban development across its limited range in northern Eurasia. Climate change poses additional threats by altering the delicate temperature and moisture conditions required for its grassland habitats and host plants. The species' restricted distribution and specialized ecological requirements make it particularly vulnerable to environmental changes.

Threat summary

Habitat

Inhabits dry grasslands, steppe meadows, and forest-steppe ecotones across northern Eurasia, typically in areas with sparse vegetation and specific grass species that serve as larval host plants. The species requires open, sun-exposed habitats with particular microclimatic conditions including well-drained soils and moderate moisture levels.
