Anobiid Bark Beetle

Adults are reddish brown to black. The head of the adult is bent downward.


Development. Eggs are laid in the bark. Larvae feed in tunnels between the bark and wood surface.                        Development takes one to two years.


Frass. The frass is a mixture of brown particles from the bark and white particles from the wood below the bark.


Habits. This beetle infests pine, spruce, and   fir, especially lumber that has small sections of bark remaining. The damage is often confused with active infestations of powderpost beetles. This beetle does not reinfest the wood and does not cause structural weakening of lumber.
