Cossoninae
Cossoninae is a subfamily of true weevils within the family Curculionidae. Members of this subfamily are characterized by their small to medium size and association with woody substrates, including timber, leaf litter, and plant roots. The group exhibits considerable diversity in habitat preference, with species found in marine/coastal environments, forest leaf litter, and specialized niches such as sand dunes and the phloem of living trees. Many species possess reduced or absent eyes (anophthalmous or microphthalmous) and exhibit endogean or cryptic lifestyles. The subfamily includes both economically significant timber pests and ecologically important decomposers.
