• Nebria brevicollis

  European Gazelle Beetle, Short-collared Gazelle Beetle

  Nebria brevicollis is a ground beetle native to Europe and the Near East that has been introduced to western North America. It is a nocturnal, opportunistic predator with a flexible life history involving photoperiod-controlled reproductive diapause. The species exhibits remarkable habitat breadth, from sea level to alpine zones, and shows phenotypic plasticity in flight muscle development based on larval nutrition. Its rapid expansion in the Pacific Northwest has raised questions about potential ecological impacts on native carabid communities.
