Arrenodes
Arrenodes is a monotypic genus of primitive weevils in the family Brentidae, containing only Arrenodes minutus, the oak timberworm. This species is a significant pest of hardwoods in eastern North America, with larvae boring into the xylem of oak, elm, beech, and poplar trees. Adults are sexually dimorphic, with females possessing long slender mouthparts for oviposition and males having broadened mandibles used for combat and courtship. The species has been introduced to the Maritime Provinces of Canada and is regulated internationally due to its potential to vector oak wilt fungus.
