Cucujus
flat bark beetles
Cucujus is a genus of flat bark beetles in the family Cucujidae, containing approximately 25 recognized species distributed across the Holarctic region. Species are dorso-ventrally compressed, brightly colored in red or red-and-black patterns, and range from 6–25 mm in length. The genus is most diverse in Asia, with indigenous species in North America, Europe, and Asia. Several species, notably C. cinnaberinus and C. clavipes, have been subjects of ecological and physiological research due to their conservation status and extreme cold tolerance adaptations.
