Overview

Orthonevra elegans is a species of small hoverflies in the subfamily Eristalinae. It is found in Europe and Asia.

Orthonevra elegans faces severe population declines primarily due to habitat loss and degradation of its specialized wetland environments. Climate change and pollution are exacerbating the loss of suitable breeding sites, while the species' narrow ecological requirements make it particularly vulnerable to environmental changes.

Threat summary

Habitat

Orthonevra elegans is associated with wetland, fen, and marshy habitats, particularly spring-fed flushes and seepages where larvae develop in consistently saturated organic substrates.

Frequently asked questions

Why is Orthonevra elegans classified as Critically Endangered?
Orthonevra elegans 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. Orthonevra elegans faces severe population declines primarily due to habitat loss and degradation of its specialized wetland environments. Climate change and pollution are exacerbating the loss of suitable breeding sites, while the species' narrow ecological requirements make it particularly vulnerable to environmental changes.
Where does Orthonevra elegans live?
Orthonevra elegans occurs in Denmark, Estonia, Finland, Germany, Poland, and Sweden (plus 1 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 Orthonevra elegans?
The main threats to Orthonevra elegans 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.
