Overview

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

Triangelbladroller faces significant pressure from habitat degradation in its specialized wetland environments, particularly through drainage of marshes and conversion of coastal areas for agriculture and development. The species' dependence on specific host plants makes it vulnerable to changes in vegetation composition caused by altered hydrology and nutrient loading. Climate change poses additional risks through shifting precipitation patterns that could affect the moisture regimes essential for both the moth and its larval food sources.

Threat summary

Habitat

This moth species inhabits coastal wetlands, marshes, and damp grasslands where its larvae feed on specific herbaceous plants. It requires areas with consistent moisture levels and diverse plant communities typical of transitional zones between terrestrial and aquatic environments.
