svart mulmblomfluga
Chalcosyrphus nigripes
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The svart mulmblomfluga faces severe population decline due to the loss of old-growth coniferous forests, particularly those containing large amounts of decaying wood essential for its larval development. Intensive forestry practices that remove dead and dying trees have eliminated critical breeding habitats across Scandinavia. Climate change poses an additional threat by altering forest composition and reducing the availability of suitable microhabitats in rotting logs and tree hollows.
Habitat
This hoverfly species inhabits mature coniferous forests, particularly spruce and pine woodlands with abundant decaying wood and tree hollows. The larvae develop specifically in rot holes and decaying heartwood of old trees, making the species entirely dependent on old-growth forest ecosystems.
