Bostrichid Powderpost Beetles

Family Bostrichidae



The Bostrichid Powderpost Beetle is typically found in wood (soft and hard) and furniture, as newer wood is its primary diet. With coloring from red-brown to black, the Bostrichid measures about 1/8 to 1/4 inch long and has a narrow, slender body.

Female Bostrichid Powderpost Beetles will bore into wood to create a tunnel to lay their eggs in. The Bostrichid Powerdpost larvae take up to a year to complete their development, but have been known to take up to five to fully mature.


There are 18 species of Bostricidea in Canada and Alaska. (Factoid Source: J. McNamara, Canadian National Collection of Insects, Arachnids and Nematodes)
