Glossosoma boltoni

Unknown

Overview

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

Glossosoma boltoni faces significant pressure from water quality degradation and habitat modification in its freshwater stream environments. Agricultural runoff and urban development in surrounding watersheds introduce pollutants and alter natural flow regimes that this caddisfly species depends upon. Climate change poses additional risks through altered precipitation patterns and increased water temperatures, which can disrupt the delicate aquatic ecosystem balance required for successful larval development.

Threat summary

Habitat

This caddisfly species inhabits clean, well-oxygenated freshwater streams and rivers with rocky or gravelly substrates. The larvae require specific water quality conditions and construct protective cases from small stones and organic debris found in their aquatic environment.

Why is Glossosoma boltoni classified as Vulnerable?
Glossosoma boltoni is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Glossosoma boltoni faces significant pressure from water quality degradation and habitat modification in its freshwater stream environments. Agricultural runoff and urban development in surrounding watersheds introduce pollutants and alter natural flow regimes that this caddisfly species depends upon. Climate change poses additional risks through altered precipitation patterns and increased water temperatures, which can disrupt the delicate aquatic ecosystem balance required for successful larval development.
Where does Glossosoma boltoni live?
Glossosoma boltoni occurs in Austria, Belgium, Canada, Czechia, Denmark, and Estonia (plus 22 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Glossosoma boltoni?
The main threats to Glossosoma boltoni are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
