Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Red Underwing faces severe population declines across its European range due to widespread loss of mature poplar and willow woodlands, its primary breeding habitat. Intensive forestry practices that favor monoculture plantations over diverse riparian forests have eliminated crucial host trees, while urban development has fragmented remaining suitable habitats. Climate change compounds these pressures by altering the timing of larval development relative to host plant phenology.
Habitat
The Red Underwing inhabits mature deciduous woodlands, particularly riparian forests dominated by poplars and willows along river valleys and wetland edges. Adults require dense canopy cover for roosting during daylight hours, while larvae depend on specific host trees including black poplar, aspen, and various willow species.
