Ceratophyus
earth-boring scarab beetles
Ceratophyus is a genus of earth-boring scarab beetles comprising approximately 13 described species. These beetles are known for constructing underground brood chambers using dung, with documented cooperative nest-building behavior between males and females in at least one species. The genus occurs across the Palaearctic region, with species documented in Russia, China, and Mongolia. Some species possess horns used in intraspecific combat.
Sericoda bembidioides
Sericoda bembidioides is a pyrophilous ground beetle inhabiting post-fire environments in boreal forests. The species shows strong positive association with fire severity but negative response to salvage logging combined with wildfire. Abundance declines sharply within three years following fire. It serves as a host for phoretic mites in the genus Antennoseius.
Stenosphenus notatus
Stenosphenus notatus is a longhorned beetle (Cerambycidae) native to eastern North America. It is notable for its exceptionally early spring emergence, appearing during the first warm days of late March and disappearing before most other longhorned beetles become active. The species is closely associated with hickory trees (Carya), where larvae develop beneath the bark of dead limbs. Adults overwinter, an unusual life history strategy among eastern U.S. cerambycids.
