Lyctus brunneus

Powderpost beetles lay their eggs in cracks of wood and the larvae tunnel into the surface, filling it with a very fine powder-like dust. Powderpost beetles have long, narrow, flat bodies that allow them to easily attack wood surfaces. These beetles are reddish-brown in color.

Color: Reddish brown to black
Legs: Six
Shape: Narrow oval
Size: 1/8 to 1/4″
Antennae: Yes
Flight: Yes

Adult powderpost beetles are very active at night, enjoy flying and are attracted to the light.

Powderpost beetles often attack hardwoods, and can be found in hardwood floors, timbers and crates, antiques and other objects made of hardwood materials.

Some researchers believe that powderpost beetles are second only to termites in the United States in their destructiveness to wood and wood products.
