It is able to live completely inside timber structures or articles made of wood such as furniture without any outside source of water. It is frequently introduced into new locations inadvertently, and causes damage to the structural timbers of buildings and to wooden objects such as furniture. ==Description== As eusocial insects, West Indian drywood termites build a colonial nest and live inside timbers, creating chambers for rearing larvae and short galleries. They resemble other drywood species in being larger and deeper-bodied than underground-dwelling termites, having shorter limbs and walking more slowly. Apart from the reproductive class, all other members of the colony are blind. They have strong jaws for chewing wood fibre, claws for gripping wooden surfaces and antennae resembling the beads of a necklace strung together. The colony consists of several different castes; reproductives including a queen, king and alates (unmated winged termites); soldiers; and pseudergates (false workers). The king and queen have dark brown, chitinous cuticles but other members of the colony have soft bodies. The soldiers are about long with colourless bodies and black, wrinkled, squarish heads. Their mandibles are relatively small and they can use their heads to block galleries to prevent marauding ants from gaining access to the nest. The sausage-shaped pseudergates are immature termites that perform the functions of a worker caste and care for the brood, excavate tunnels, consume wood and feed the other members of the colony. The alates have two pairs of transparent membranous wings with dark veins running along near the leading edge. Identification of termites species is difficult and is usually made as a result of the appearance and structure of the soldiers' heads.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cryptotermes brevis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
