Cheilosia frontalis

Overview

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

Cheilosia frontalis faces severe population declines primarily due to the degradation and fragmentation of its specialized wetland habitats. Agricultural intensification and drainage of bog and fen systems have eliminated critical breeding sites, while climate change is altering the hydrology of remaining wetlands. The species' narrow ecological requirements and limited dispersal ability make it particularly vulnerable to habitat loss.

Threat summary

Habitat

This hoverfly species inhabits pristine bog and fen ecosystems, particularly areas with abundant Sphagnum moss and specialized flowering plants. It requires undisturbed wetland margins with specific moisture regimes and native plant communities for both larval development and adult foraging.

Why is Sump-urtesvirreflue classified as Endangered?
Sump-urtesvirreflue 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. Cheilosia frontalis faces severe population declines primarily due to the degradation and fragmentation of its specialized wetland habitats. Agricultural intensification and drainage of bog and fen systems have eliminated critical breeding sites, while climate change is altering the hydrology of remaining wetlands. The species' narrow ecological requirements and limited dispersal ability make it particularly vulnerable to habitat loss.
Where does Sump-urtesvirreflue live?
Sump-urtesvirreflue occurs in Åland Islands, Austria, Denmark, Estonia, Finland, and France (plus 13 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 Sump-urtesvirreflue?
The main threats to Sump-urtesvirreflue 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.
