Xestobium rufovillosum is a type of wood-boring beetle that is commonly known as the deathwatch beetle. This beetle gets its name from the distinctive tapping sounds it makes as it bores into wood. Synonyms for the Xestobium rufovillosum include Anobium pertinax, Anobium rudicollle and Anobium tessellatum. These synonyms are often used interchangeably and refer to the same species of beetle. The deathwatch beetle is considered a pest as it can cause damage to the wooden structures it inhabits. However, it also plays an important role in decomposing dead wood in forests, helping to recycle nutrients and maintain ecosystem balance.
