Hadrobregmus is a genus of beetles in the family Ptinidae. [1]
Hadrobregmus denticollis is a species of death-watch beetle in the family Anobiidae.
In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Insects with hardened wing covers were brought together under the name Coleoptera.
Priobium is a genus of wood-boring, death-watch beetles ranging in western distribution in North America. Their antennae are without a distinct club. A pronotum similar to Hadrobregmus is characteristic. The various species appear similar. The larvae consume conifers.
Hadrobregmus pertinax is a species of woodboring beetle within the genus Hadrobregmus of the family Ptinidae. 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.
Hadrobregmus quadrulus is a species in the family Ptinidae, in the order Coleoptera ("beetles"). Hadrobregmus quadrulus is found in North America.
Hadrobregmus alternatus is a species of death-watch beetle in the family Ptinidae. It is found in North America.
Hadrobregmini is a tribe of death-watch beetles in the family Ptinidae. There are at least 3 genera and about 16 described species in Hadrobregmini.
