Hylotrupes is a monotypic genus of woodboring beetles in the family Cerambycidae, the longhorn beetles. The sole species, Hylotrupes bajulus, is known by several common names, including house longhorn beetle, old house borer, and European house borer. Originating in Europe, and having been spread in timber and wood products, the beetle now has a practically cosmopolitan distribution, including Southern Africa, Asia, the Americas, Australia, and much of Europe and the Mediterranean.
