Sympetrum evanescens

Unknown

Overview

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

Sympetrum evanescens faces severe population decline primarily due to wetland habitat destruction and degradation across its limited range. Agricultural intensification and urban development have eliminated many of the shallow, vegetated ponds and marshes essential for larval development. Water pollution from agricultural runoff and climate-induced changes to precipitation patterns further threaten the remaining suitable breeding sites.

Threat summary

Habitat

This dragonfly species inhabits shallow, vegetated freshwater wetlands including ponds, marshes, and slow-moving streams with abundant emergent vegetation. The larvae require clean, well-oxygenated water with suitable substrate for development, while adults hunt for prey in adjacent grasslands and open areas.

Frequently asked questions

Why is Sympetrum evanescens classified as Critically Endangered?
Sympetrum evanescens is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Sympetrum evanescens faces severe population decline primarily due to wetland habitat destruction and degradation across its limited range. Agricultural intensification and urban development have eliminated many of the shallow, vegetated ponds and marshes essential for larval development. Water pollution from agricultural runoff and climate-induced changes to precipitation patterns further threaten the remaining suitable breeding sites.
Where does Sympetrum evanescens live?
Sympetrum evanescens occurs in Venezuela. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Sympetrum evanescens?
The main threats to Sympetrum evanescens 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.
