Overview

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

The Südliche Mulmschwebfliege faces severe habitat loss due to intensive forestry practices that remove the dead and decaying wood essential for its larval development. Climate change poses an additional threat by altering forest composition and reducing the availability of suitable microhabitats. The species' dependence on specific tree species and deadwood characteristics makes it particularly vulnerable to forest management practices that prioritize timber production over biodiversity conservation.

Threat summary

Habitat

This hoverfly species inhabits mature deciduous and mixed forests, particularly those with abundant deadwood and decaying timber. The larvae develop specifically in the moist, decomposing wood of various tree species, requiring stable forest environments with minimal human disturbance.
