Overview

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

The Twin-spot Fritillary faces severe population declines across its range due to habitat loss and degradation of its specialized grassland ecosystems. Agricultural intensification, urban development, and changes in traditional land management practices have eliminated or fragmented critical breeding habitats. Climate change further threatens remaining populations by altering the delicate ecological conditions required for both the butterfly and its host plants.

Threat summary

Habitat

Inhabits flower-rich grasslands, meadows, and steppe environments, particularly those maintained by traditional grazing or mowing regimes. Requires areas with abundant violet species (Viola) which serve as larval host plants, typically in calcareous or nutrient-poor soils at elevations ranging from lowlands to montane zones.
