Overview

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

The Silver Colonel faces severe habitat degradation from agricultural intensification and urban development across its European range. Wetland drainage and pollution from agricultural runoff have eliminated many breeding sites, while climate change is altering the moisture regimes essential for larval development. The species' specialized requirements for clean, shallow water bodies with specific vegetation make it particularly vulnerable to environmental changes.

Threat summary

Habitat

The Silver Colonel inhabits clean, shallow freshwater environments including marshes, pond margins, and slow-flowing streams with abundant emergent vegetation. Adults are typically found near water bodies where they feed on nectar, while larvae develop in the muddy substrates of these aquatic habitats.
