Overview

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

Neoascia annexa faces severe population declines primarily due to the loss and degradation of its specialized wetland habitats across northern Europe. Agricultural intensification and drainage of bog and fen systems have eliminated critical breeding sites, while climate change threatens the delicate hydrological balance these hoverflies require. The species' narrow ecological requirements and limited dispersal ability make it particularly vulnerable to habitat fragmentation.

Threat summary

Habitat

This specialized hoverfly inhabits pristine bog and fen environments, particularly areas with Sphagnum moss and sedge communities. The species requires clean, nutrient-poor wetlands with stable water levels and minimal human disturbance.
