Notch-wing Neb, Cottongrass Borer

Monochroa suffusella

Unknown

Overview

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

The Notch-wing Neb faces severe population decline primarily due to the destruction and degradation of its specialized wetland habitats. Drainage of peat bogs and marshlands for agriculture and development has eliminated critical breeding sites where cottongrass grows. Climate change compounds these pressures by altering wetland hydrology and shifting the distribution of host plants, while habitat fragmentation isolates remaining populations and reduces genetic diversity.

Threat summary

Habitat

This specialized moth inhabits peat bogs, wet heathlands, and marshy areas where cottongrass (Eriophorum species) grows abundantly. The larvae bore into cottongrass stems and seed heads, making the species entirely dependent on these specific wetland plant communities.
