Standard Common Name

Powder Post Borer

Size range

3 mm - 4 mm

Distribution

The Powder Post Borer is found throughout Australia.

Habitat

The Powder Post Borer lives in urban areas.

Other behaviours and adaptations

Female Powder Post Borers lay eggs into hardwood timber and, on hatching, the grubs feed on the starch present in the wood. The larvae pupate into adult beetles, which then bore their way out of the wood.

Economic/social impacts

The Powder Post Borer leaves timber riddled with small holes approximately 2 mm in diameter, seriously affecting its strength. As a result, New South Wales legislation only allows a limited amount of susceptible types of wood to be used in building construction.
