Anoblum Punctatum (Common Furniture Beetle)

3-5mm Long. Thorax hooded over head. Rows of small pits on wing cases. Last three nodules of the antennae larger than the others. Red brown in colour.

Softwoods and European hardwoods. Sapwood only affected if rot present. Also common in old birch/beech/oak plywoods using animal based glues.

Emergence holes circular, 1-2mm diameter. Tunnels random orientation but mainly in direction of grain. Old extinct damage often accompanied by fine pin holes of parasitic wasps.

Cream coloured, lemon or barrel shaped pellets, gritty when rubbed between fingers.

Bark borer, Pinhole borer, Ptilinus Beetle, Lyctus powderpost Beetle, Deathwatch Beetle, Wood boring weevil.

Xestblum Rufovillosum (Deathwatch Beetle)

6-9mm long chocolate brown. Patches of yellow hairs. Found on or beneath timbers, March to June, particularly in warm weather when they may be heard and seen. tapping with their heads.

Almost entirely confined to hardwoods especially oak. The wood must be partially decayed by fungus to initiate infestation. Generally confined to old buildings.

Emergence holes circular 2-3mm diameter. Tunnels, random orientation but mainly in the direction of the grain.

Cream or biscuit coloured disc or bun shaped pellets, gritty when rubbed between fingers.

Bostrychid powderpost beetle, Bark borer beetle. Dermestid beetle, Tenebrionid beetle, Bees or Wasps, Marine borer.

Lyctus brunneus (Powderpost beetle)

4-7mm long, reddish brown to black, flattened & elongated with roughly parallel sides. Found around damaged timber in May to September but all year round in heated buildings.

Sapwood of tropical and European hardwoods, principally oak and elm with large oires and high starch content. Not found in softwoods. Block or strip flooring also affected.

Emergence holes circular, 1-2mm diameter. Tunnels usually parallel to grain. In later stages leaves thin intact layer on surface.

Cream coloured, fine talc-like powder. May accumulate in small piles beneath emergence holes.

Common furniture beetle, Ptilinus beetle, Pinhole borer beetle, bark borer beetle, Bostrychid powderpost beetle.

Pentarthrum huttoni & Euophryum confine (Wood boring weevil)

3- 5 mm long, brownish black, distinctive long snout. Antennae 1/3 distance along snout. Found around infested wood all year long particularly in the summer or if the timber dries out.

Decayed softwoods and hardwoods in damp conditions. Damage secondary to fungal decay. Also attacks plywood in these conditions.

Emergence holes small ragged approx 1mm in diameter. Numerous tunnels normally in the direction of the grain. Tunnels often bark through to the surface of the timber.

Fine, gritty.

Common furniture beetle.

Hylotrupes bajulus (House longhorn beetle)

10-12mm long, black or dull brown. Smooth central line on thorax flanked by two shiny black bumps. Two grey patches of hair on wing covers. Found around infested timber in July-October.

Sapwood of most softwoods, particularly in roof timbers. Common only in SW London and Surrey. Isolated infestations in other parts of the country can stem from infested packing cases in transit. Can attack plywood.

Emergence holes few, large oval 6-10mm in largest dimension, often ragged at edges. Almost complete disintegration of sapwood but leaving thin, intact surface skin.

Cream coloured, sausage shaped pellets with small chips or wood fibres also present. Gritty when rubbed between fingers. Tunnels are densely packed with bore dust. Tunneling near to the surface often leaves a rippled effect on the timber.

Forest longhorn beetle, Jewel beetle, Wharf borer beetle, Wood wasp, Teriebrionid beetle, Bostrychid powderpost beetle.
