General Sapwood
of tropical and European hardwoods, principally oak and elm, with
large pores and high starch content. Not found in softwoods.
Solid limber Damage
almost always originates in stockyard or storeroom infestation.
Only found in timber containing adequate starch and usually with
pores large enough for female beetle to lay eggs in. Common in furniture
and occasionally in block or strip flooring.
Panel products Veneers,
plywood and blackboard are susceptible.

Emergence holes Circular,
1 - 2 mm diameter.
Tunnels Circular,
1 - 2 mm diameter, random orientation but mostly parallel to grain.
May be missed in initial stages of attack. In later stages sapwood
almost completely disintegrates, leaving thin, intact surface skin
of wood.
Bore dust Cream-coloured.
Fine, talc-like when rubbed between fingers. May accumulate in small
piles beneath emergence holes. Easily shaken out of tunnels.
Likely misidentifications Common
furniture beetle, Ptilinus beetle, pinhole borer beetle, bark borer
beetle, Bostrychid powderpost beetle.
