Ptilocolepus granulatus

Unknown

Overview

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

Ptilocolepus granulatus faces significant pressure from habitat degradation in its limited range within the Western Ghats of India. Stream pollution from agricultural runoff and urban development threatens the clean, fast-flowing waters this caddisfly species requires for larval development. Deforestation in catchment areas alters water flow patterns and increases sedimentation, further compromising the aquatic ecosystems where this species breeds.

Threat summary

Habitat

This caddisfly species inhabits clean, fast-flowing streams and rivers in the Western Ghats mountain range of India. The larvae require well-oxygenated waters with rocky substrates and minimal sedimentation, typically found in forested catchments at moderate elevations.
