Lyctini
Powderpost beetles (tribe)
Lyctini is a tribe of wood-boring beetles within the family Bostrichidae, commonly known as powderpost beetles. Members are characterized by their ability to digest cellulose through symbiotic yeasts, enabling them to infest and damage seasoned hardwoods. The tribe includes economically significant pests such as species in the genus Lyctus. These beetles are distinguished from other Bostrichidae by their small size, cylindrical bodies, and reduced elytral declivity.
