What sound do death watch beetles make that relates to their name?

The name "death watch beetle" is derived from the distinct sound these insects make, which is produced when they bang their heads against the walls of their galleries. This action creates a clicking sound, and historically, it was believed that the noise was an omen of impending death, hence the name. The sound they create is not melodic or consistent; rather, it is an intermittent tapping or clicking that can be heard when the beetles are active, especially in silence, contributing to their ominous association. This behavior is not a typical representation of the sounds made by most other insect species and aligns specifically with the behavior of death watch beetles, reinforcing their unusual place in folklore and common naming conventions.
