The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beetle. Adult beetles that emerge from wood may also be found in the summer months.
The sole species, Hylotrupes bajulus, is known by several common names, including house longhorn beetle, old house borer, [1] and European house borer. [2] In South Africa it also is known as the Italian beetle because of infested packing cases that had come from Italy. [3] Hylotrupes is the only genus in the tribe Hylotrupini.

The ambrosia beetles (such as Xyleborus) feed on fungal "gardens" cultivated on woody tissue within the tree. Ambrosia beetles carry the fungal spores in either their gut or special structures, called mycangia, and infect the trees as they attack them. Once a beetle chooses a tree, they release spores of this fungus along tunnels within the tree.
The steely blue beetle (Korynetes caeruleus) is a predator of the deathwatch beetle and of the common furniture beetle (Anobium punctatum). The adult female blue beetle lays her eggs in the exit holes made by the emerging borers, and the carnivorous larvae wander through the galleries made by the wood-borers, feeding on their larvae.
