Overview

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

The White-spotted Pinion faces severe population declines primarily due to the loss and degradation of its specialized woodland habitats across Europe. Agricultural intensification and urban development have fragmented the mature deciduous forests this species requires for breeding and larval development. Climate change is altering the timing of host plant availability, disrupting the moth's synchronized life cycle with its preferred food sources including elm and poplar trees.

Threat summary

Habitat

The White-spotted Pinion inhabits mature deciduous and mixed woodlands across Europe, particularly favoring areas with elm, poplar, and willow trees.
