Overview

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

Tjärblomstermal faces severe habitat loss due to the decline of its host plant, Silene viscaria (sticky catchfly), across Scandinavia. Urban development and agricultural intensification have fragmented the dry grassland and rocky outcrop habitats where both the moth and its host plant occur. Climate change poses an additional threat by altering the phenology of the host plant, potentially disrupting the moth's carefully timed life cycle that depends on Silene viscaria for larval development.

Threat summary

Habitat

This specialized moth inhabits dry grasslands, rocky outcrops, and open woodland edges where its host plant Silene viscaria grows. The species is restricted to areas with well-drained, often calcareous soils in Scandinavia, particularly favoring south-facing slopes and disturbed ground where the sticky catchfly thrives.
