Overview

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

The Sallow Clearwing faces severe population declines primarily due to the loss and degradation of its specialized wetland habitats, particularly areas with mature sallow trees. Urban development and agricultural intensification have eliminated many traditional breeding sites, while changes in woodland management practices have reduced the availability of suitable host trees. Climate change poses an additional threat by altering the phenology of both the moth and its host plants, potentially disrupting critical breeding cycles.

Threat summary

Habitat

The Sallow Clearwing inhabits wetland margins, carr woodland, and areas with abundant sallow trees (Salix species), particularly where these occur near water sources. The species requires mature sallow stands for larval development, with adults typically found in damp woodland edges and marshy areas throughout its European range.
