Hylotrupes bajulus, a species originating in Europe, and having been spread in timber and wood products, now has a practically cosmopolitan distribution, including Southern Africa, Asia, the Americas, Australia, and much of Europe and the Mediterranean. H. bajulus is probably the most feared and dangerous species of longhorn beetle in Europe - it damages timber (especially wood from pines, spruces, firs and larches) in rural and urban buildings and causes large financial losses every year. Larval development in completely dead debarked processed coniferous wood. The larvae are able to survive and develop in the dry timber for up to 17 years, in addition, adults can mate and reproduce inside the infested wooden structures without leaving the larval gallery. This makes the detection of an attack very difficult. Several generations of larvae can feed in timber without leaving visible traces on the surface, while its inner part can be completely destroyed and changed into a dust. Adults, active from June to September, are during the day hidden in crevices or gaps between the beams. Sometimes it is possible to find beetles in the wild in old pine forests [❖][✧].
