Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction. The lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.
The females locate the host larvae living concealed inside wood by generating vibrations by tapping the tips of their antennae against the wood surface. The vibrations are picked up by the modified fore legs. [3] [8] After locating the host, the female drills into the wood with the very long ovipositor and lays the egg. The egg is very elongate ...

The protective role of the shells is lost because the animal spends all its life surrounded by wood. [6] Teredo navalis develops from eggs to metamorphosing larvae in about five weeks. They spend half of this time in the mother's gill chamber before being discharged as free-swimming larvae into the sea.

[21] Bookworm is a word-forming puzzle video game developed by PopCap Games that follows Lex, an actual bookworm who accompanies the player as they form words from the deck.

Burl wood is very hard to work with hand tools or on a lathe, because its grain is twisted and interlocked, causing it to chip and shatter unpredictably. This "wild grain" makes burl wood extremely dense and resistant to splitting, which made it valued for bowls, mallets, mauls and "beetles" or "beadles" for hammering chisels and driving wooden ...
The mycophagous phase of the life cycle takes place in dead or dying wood, where the nematodes live and feed upon fungi, rather than the wood itself. The nematode cannot travel outside of the wood independently; it must be transported by an insect vector. B. xylophilus has the shortest life cycle of any known parasitic nematode. In laboratory ...
