Overview

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.

Threat summary

Habitat

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.
