Furniture Beetle Anobium punctatum

The (Common) Furniture Beetle is some 3-4mm long with a rounded head and thorax. Adults do not eat. Females lay eggs in cracks or holes in dead wood and it is larvae that bore the wood holes.

The larva lives 3-4 years eating in the wood; its job is to recycle dead wood. It reaches some 7mm length before pupating just below the wood surface. The new adult breaks through, creating the "woodworm" exit holes; new holes have a little sawdust.
