Overview

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

The Mouse-ear Groundling faces severe population decline primarily due to habitat degradation from agricultural intensification and urban development across its limited European range. Overgrazing by livestock has significantly reduced the quality of its specialized grassland habitats, while climate change is altering the phenology of its host plants. The species' highly fragmented populations are increasingly vulnerable to local extinctions due to reduced genetic diversity and limited dispersal capabilities.

Threat summary

Habitat

This micro-moth species inhabits dry, calcareous grasslands and chalk downs across parts of Europe, particularly favoring areas with sparse vegetation and exposed soil. It requires specific host plants in the Caryophyllaceae family, typically found in unimproved grassland ecosystems with low nutrient levels.
