Overview

Acalles echinatus is species of beetle from the family Curculionidae. It inhabits Europe and the Transcaucasia.

Acalles echinatus faces significant threats from habitat degradation and fragmentation of its specialized woodland environments. Climate change and human encroachment into its native range are reducing suitable habitat areas, while the species' limited dispersal ability makes population recovery difficult once local extinctions occur.
