The death watch beetle (Anobiidae) is a woodboring beetle, namely a beetle whose larvae are xylophagous. The adult is approximately 7 mm long. The larva can be up to 11 mm long.
Deathwatch beetles are closely related to the drugstore and cigarette beetles, which are stored-product pests. Adults communicate with each other and probably locate mates by tapping their heads against wood, usually at night. (Deathwatch beetles supposedly acquired their name during medieval European times from people who heard the tapping while sitting up with a sick or dying person during the night.) Adults are reddish to dark brown and lay eggs in crevices or small openings or pores in unfinished wood. Two years may be required to complete each generation.
