Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
The Forester moth (Adscita mannii) faces severe population declines due to habitat loss from agricultural intensification and urban development across its European range. Climate change and the degradation of traditional grassland management practices have further reduced suitable breeding sites, while the species' specialized larval host plant requirements make it particularly vulnerable to environmental changes.
Key Facts
Habitat & Distribution
Inhabits chalk downs, limestone grasslands, and other calcareous grassland habitats, typically in areas with short turf where the larval host plants in the Polygonaceae family occur. Adults are found in flower-rich grasslands and meadows, particularly those maintained by traditional grazing or mowing regimes.
