Overview

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

The Giant Water-veneer faces severe population declines primarily due to wetland habitat destruction and degradation across its European range. Agricultural intensification and urban development have eliminated many of the species' essential reed bed and marsh habitats. Water pollution from agricultural runoff and industrial sources further degrades remaining wetland ecosystems, while climate change alters hydrological patterns critical for the moth's aquatic larval stage.

Threat summary

Habitat

The Giant Water-veneer inhabits freshwater wetlands, particularly reed beds, marshes, and the margins of slow-flowing rivers and canals. The species requires clean water systems with abundant emergent vegetation, especially Phragmites reeds where larvae develop within stem tissues.
