Overview

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

The Rosy-striped Knot-horn faces significant pressure from habitat degradation in its specialized wetland environments. Agricultural intensification and drainage of marshy areas have reduced the availability of suitable breeding sites where larvae develop in plant stems. Climate change poses additional risks through altered precipitation patterns that affect the moisture levels critical for this species' reproductive success.

Threat summary

Habitat

This moth species inhabits marshy areas, wet meadows, and the margins of freshwater bodies where its host plants thrive. The larvae require specific moisture conditions and develop within the stems of sedges and other wetland vegetation.
