Overview

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

The Ruddy Flat-body faces severe population decline primarily due to habitat degradation and loss of its specialized host plants. Agricultural intensification and urban development have fragmented the wetland and marshy areas where this moth depends on specific sedge and grass species for larval development. Climate change is altering the hydrology of its preferred habitats, while pesticide use in surrounding agricultural areas poses additional chemical threats to both adult moths and their larval food sources.

Threat summary

Habitat

The Ruddy Flat-body inhabits wetland margins, marshy grasslands, and damp meadows where its larval host plants, primarily sedges and moisture-loving grasses, thrive. This specialized moth requires the specific microhabitat conditions found in transitional zones between aquatic and terrestrial environments.
