The risk to Australia
The lesser auger beetle poses a serious biosecurity risk because it feeds on various hardwood timbers and bamboo. The damage is caused by larvae tunnelling in the wood which significantly reduces the quality of the timber. The spread of the lesser auger beetle could have devastating effects on Australia’s furniture and timber industries and native forests.
What the lesser auger beetle looks like
Adult beetles range from 6 to13 millimetres in length and are between 2 to 3.5 millimetres wide. Their bodies are moderately shiny and their colour ranges from a reddish brown to a brownish black. Males have two incurved hook-like projections at the back end of their bodies.
Eggs are laid on rough surfaces of sawn timber and logs, in holes, cracks or short tunnels made by the female. The larvae are white to yellowish in colour, curved in shape and up to 15 millimetres long. The larval boring holes are about 6 millimetres wide and can wind for several centimetres.
What to look for
The lesser auger beetle is likely to enter Australia in imported timber, dunnage (for example crates, pallets and other packaging), furniture and souvenirs. Look out for circular exit holes and fine floury frass in hardwood timber.
