Brachyopa vittata

Local name: större savblomfluga

UnknownNTEUNTEU

Overview

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

Brachyopa vittata faces severe population decline primarily due to the loss of old-growth deciduous forests containing the large, hollow trees essential for its larval development. The species depends on specific microhabitats within tree holes where sap accumulates, making it extremely vulnerable to forestry practices that remove mature and dead standing timber. Climate change compounds these pressures by altering forest composition and reducing the availability of suitable breeding sites.

Threat summary

Habitat

This hoverfly species inhabits mature deciduous and mixed forests, particularly those with abundant old trees containing natural cavities and hollow trunks. The larvae develop specifically in tree holes where sap and organic matter accumulate, requiring undisturbed forest environments with a continuous supply of dead and decaying wood.

Frequently asked questions

Why is större savblomfluga classified as Endangered?
större savblomfluga 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. Brachyopa vittata faces severe population decline primarily due to the loss of old-growth deciduous forests containing the large, hollow trees essential for its larval development. The species depends on specific microhabitats within tree holes where sap accumulates, making it extremely vulnerable to forestry practices that remove mature and dead standing timber. Climate change compounds these pressures by altering forest composition and reducing the availability of suitable breeding sites.
Where does större savblomfluga live?
större savblomfluga occurs in Austria, Belgium, Bulgaria, Denmark, Estonia, and Finland (plus 14 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
