DEATHWATCH BEETLE

Like all other beetles, this deathwatch beetle preserved in amber that dates back to the Eocene epoch (54 to 37 million years ago) possesses very interesting characteristics. During their larval stage, deathwatch beetles store the nutrients they need as fat tissue and use them during their adult stage, not taking on any further nutrients from the outside. These insects, which live in wood, are able to digest cellulose with the help of bacteria and fungi in their stomachs. During the mating period, they knock on the tunnels they"ve dug in the wood, producing a noise that can easily be heard by human beings. Deathwatch beetles have had these fascinating characteristics for millions of years.
