Powderpost Beetles

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.
