Ceratopsyche silfvenii

Unknown

Overview

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

Ceratopsyche silfvenii faces significant pressure from habitat degradation caused by agricultural expansion and urban development within its limited range. Water pollution from agricultural runoff and industrial discharge poses a particular threat to this caddisfly species, as larvae require clean, well-oxygenated stream environments for successful development. Climate change-induced alterations to precipitation patterns and stream flow regimes further compromise the specialized aquatic habitats this species depends upon.

Threat summary

Habitat

This caddisfly species inhabits clean, fast-flowing streams and rivers with rocky substrates in temperate regions. The larvae require well-oxygenated water with specific temperature ranges and are particularly sensitive to water quality changes.
