Brachyopa panzeri
Brachyopa panzeri is a small hoverfly species with a distinctive dark metallic sheen and pale markings on its abdomen. This specialized dipteran plays a crucial ecological role as both a pollinator of woodland flowers and as a predator, with its larvae feeding on aphids and other soft-bodied insects in tree hollows and sap runs.

Species Profile
Brachyopa panzeri is a small hoverfly species with a distinctive dark metallic sheen and pale markings on its abdomen. This specialized dipteran plays a crucial ecological role as both a pollinator of woodland flowers and as a predator, with its larvae feeding on aphids and other soft-bodied insects in tree hollows and sap runs.
Brachyopa panzeri, a specialized hoverfly species, faces significant population declines primarily due to habitat loss and degradation of old-growth forests where it depends on tree holes and sap runs for breeding. The species' narrow ecological requirements and limited dispersal ability make it particularly vulnerable to forest fragmentation and changes in forest management practices.
Key Facts
Habitat & Distribution
Brachyopa panzeri inhabits mature deciduous and mixed forests, particularly areas with old beech, oak, and birch trees that have natural wounds, rot holes, or sap runs. The species requires undisturbed woodland environments with a continuous canopy and abundant decaying organic matter in tree cavities.
Threats
