Species Profile
Euthrix potatoria, the drinker, is an orange-brown moth of the family Lasiocampidae.
The Drinker moth faces significant population declines across its range due to habitat loss and degradation of wetland ecosystems where its larvae depend on sedges and grasses. Agricultural intensification, urban development, and climate change are reducing the availability of suitable breeding habitats, while pollution and altered water regimes further threaten the wet grassland communities this species requires.
Key Facts
Habitat & Distribution
Wet grasslands, marshes, fens, and boggy areas where sedges, rushes, and coarse grasses grow, typically in lowland regions with high moisture content. The species also occurs in damp meadows, reed beds, and the margins of ponds and slow-moving waterways.
Threats
Agricultural intensification and pesticide use
Wetland habitat loss and drainage
Climate change altering precipitation patterns
Urban development and infrastructure expansion
Water pollution and eutrophication
