Overview

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

The gul ullblomfluga faces severe habitat loss due to the decline of old-growth deciduous forests across Scandinavia, particularly ancient beech and oak woodlands that provide the hollow trees essential for its larval development. Agricultural intensification and forest management practices that remove dead and dying trees have eliminated critical breeding sites. Climate change poses an additional threat by altering the phenology of flowering plants that adults depend on for nectar, potentially creating mismatches between emergence timing and food availability.

Threat summary

Habitat

This hoverfly species inhabits mature deciduous forests, particularly ancient beech and oak woodlands with abundant dead wood and tree hollows. The larvae develop in water-filled tree holes and rot cavities, while adults forage on flowers in forest clearings and edges.
