The adult is black, with yellow hairs at the back corners of its head, and is 4-5 mm long. The larva is white, about 5 mm long, and lives in decaying wood. The larval stage lasts many years. The Finnish name is "kuolemankello," literally the "clock of death," which comes from the sound resembling the ticking of a clock, made by the male striking its head against the surface of the wood in order to attract a mate.〔 It is the most destructive insect of buildings in Finland, where it survives the long winters in below-freezing temperatures.〔 Because the larva lives in decaying wood, its presence indicates moisture damage. Resolution of the moisture problem will cause the beetle to leave. ==See also== * Death watch beetle * Priest killer 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「Hadrobregmus pertinax」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.
