Sciaphobus ningnidus
Local name: blåhallonvivel
The blåhallonvivel (Sciaphobus ningnidus) is a distinctive weevil species characterized by its metallic blue-black elytra and robust, curved rostrum adapted for feeding on raspberry canes. This specialized beetle plays a crucial role in northern European ecosystems as both a herbivore of wild Rubus species and as prey for insectivorous birds and spiders.

Species Profile
The blåhallonvivel (Sciaphobus ningnidus) is a distinctive weevil species characterized by its metallic blue-black elytra and robust, curved rostrum adapted for feeding on raspberry canes. This specialized beetle plays a crucial role in northern European ecosystems as both a herbivore of wild Rubus species and as prey for insectivorous birds and spiders.
Sciaphobus ningnidus faces significant threats from habitat degradation and fragmentation due to agricultural expansion and urban development across its range. Climate change is altering the species' preferred environmental conditions, while invasive plant species compete with native vegetation that the weevil depends upon for survival.
Key Facts
Habitat & Distribution
This weevil species inhabits temperate grasslands, meadows, and forest edges with specific host plant associations, typically found in areas with well-drained soils and moderate moisture levels. The species shows preference for semi-natural habitats with diverse herbaceous vegetation at elevations ranging from lowlands to mid-mountain zones.
