Overview

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

Scotopteryx coarctaria faces severe population decline primarily due to habitat loss from agricultural intensification and urban development across its European range. The species' specialized requirements for calcareous grasslands and chalk downs make it particularly vulnerable to land-use changes. Climate change poses an additional threat by altering the distribution and phenology of its host plants, potentially disrupting breeding cycles and larval development.

Threat summary

Habitat

This moth species inhabits calcareous grasslands, chalk downs, and limestone areas across parts of Europe. The larvae feed on specific host plants including wild thyme and other low-growing herbs typical of these alkaline soil environments.
