Hadromorphus inflatus
Hadromorphus inflatus is a species of click beetle (Elateridae) native to northeastern North America. The species was previously classified under the genus Porrhodites and has been identified as a potential subnivium specialist—an arthropod adapted to the air pocket beneath winter snowpack. Research suggests it dominates subnivium communities during winter months and is rare or inactive during summer, indicating a specialized cold-season life history.
