Cossidae, commonly known as the carpenter moths, is a family of moths found worldwide. They are characterized by their robust bodies and long, narrow wings. The larvae of Cossidae are known for their wood-boring habits, often tunneling into the trunks of trees, which can cause damage to timber and living trees. These moths typically have a muted coloration, helping them blend into their surroundings. Adult Cossidae are nocturnal and are attracted to light. The family includes several genera, with some species being significant pests in forestry and agriculture, impacting trees and wood products.
