Steely Blue Beetle

Korynetes caeruleus

Appearance

•  Adult - 4mm. Shiny blue colour.

Lifecycle

•  Eggs are laid on the surface of wood by or just inside exit holes.
•  Larvae live inside wood that has been infested by wood boring insects, where they feed on the larvae of these wood-damaging insects.
•  Adult: After emergence they mate, lay eggs and then die.

Habits

•  Predator of common furniture beetle (Anobium punctatum) and death watch beetle (Xestobium rufovillosum) – so its presence indicates a heavy infestation of either wood-boring insect.
•  The steely blue beetle is not capable of damaging wood.
