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
The Hodotermitidae (from Greek ὁδός (hodós), travelling; Latin termes, woodworm) are a basal Old World family of termites known as the harvester termites. [1] They are distinguished by the serrated inner edge of their mandibles, and their functional compound eyes which are present in all castes. [2]
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.
[1] The larvae are creamy-white with six legs, black jaws, a pair of eyespots on either side of the head. They grow to about 11 mm (0.4 in) long, making them the largest Ptininae found in Britain. These larvae are distinctive due to a swollen thoracic region and multiple golden setae. [1] The pupa, when newly formed, is shiny and milky white in ...
Woodworm holes and burrows exposed in wooden floorboard. The first step in pest control is prevention. Particularly important in this respect is to keep the timber dry - below 16% moisture content. A relative humidity within the building above 60% may lead to an infestation, and timber moisture content below 12% is too dry for an infection to ...
The stems are straight, growing to 0.8–1.2 m (2 ft 7 in – 3 ft 11 in) (and rarely over 1.5 metres (4 ft 11 in)) tall, grooved, branched, and silvery-green. Leaves are spirally arranged, greenish-grey colored above, white below, covered with silky silvery-white trichomes , and bearing minute oil-producing glands.
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information.
The existence of huge mollusks was established for centuries and studied by the scientists, based on the shells they left behind that were the size of baseball bats (length 1.5 metres (4 ft 11 in), diameter 6 cm (2.4 in)).
