Overview

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

Empis borealis faces severe population declines primarily due to habitat degradation in its specialized wetland environments. Agricultural intensification and drainage of marshy areas have eliminated critical breeding sites, while climate change is altering the hydrological patterns essential for this dance fly's reproductive cycle. Pollution from agricultural runoff further degrades the water quality in remaining suitable habitats.

Threat summary

Habitat

This dance fly species inhabits marshy wetlands, bog margins, and areas with slow-moving or standing water where vegetation provides both shelter and hunting grounds. It requires specific moisture levels and plant communities typical of northern European wetland ecosystems.

Frequently asked questions

Why is wilgedansvlieg classified as Endangered?
wilgedansvlieg is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Empis borealis faces severe population declines primarily due to habitat degradation in its specialized wetland environments. Agricultural intensification and drainage of marshy areas have eliminated critical breeding sites, while climate change is altering the hydrological patterns essential for this dance fly's reproductive cycle. Pollution from agricultural runoff further degrades the water quality in remaining suitable habitats.
Where does wilgedansvlieg live?
wilgedansvlieg occurs in Åland Islands, Austria, Belgium, Denmark, Estonia, and Finland (plus 14 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 wilgedansvlieg?
The main threats to wilgedansvlieg 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.
