Overview

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

Chrysogaster virescens faces severe population declines primarily due to the destruction and fragmentation of its specialized wetland breeding habitats through agricultural intensification and urban development. The species' dependence on specific aquatic plant communities for larval development makes it particularly vulnerable to water pollution from agricultural runoff and changes in water quality. Climate-induced alterations to precipitation patterns and wetland hydrology further threaten the delicate ecological balance required for successful reproduction.

Threat summary

Habitat

This hover fly species inhabits shallow, nutrient-rich wetlands, marshes, and pond margins with abundant emergent and floating vegetation. The larvae develop in decaying organic matter within aquatic plant communities, while adults feed on nectar from wetland flowers and require nearby areas of undisturbed vegetation for overwintering.

Frequently asked questions

Why is Skimmerblomfluga classified as Endangered?
Skimmerblomfluga 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. Chrysogaster virescens faces severe population declines primarily due to the destruction and fragmentation of its specialized wetland breeding habitats through agricultural intensification and urban development. The species' dependence on specific aquatic plant communities for larval development makes it particularly vulnerable to water pollution from agricultural runoff and changes in water quality. Climate-induced alterations to precipitation patterns and wetland hydrology further threaten the delicate ecological balance required for successful reproduction.
Where does Skimmerblomfluga live?
Skimmerblomfluga occurs in Denmark, Finland, France, Germany, Greece, and Ireland (plus 6 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
