Lyctus brunneus is a species of beetle in the family Bostrichidae (formerly in the family Lyctidae, which is now a subfamily of Bostrichidae), with a worldwide distribution, being present in tropical Africa, Oceania, the Palearctic (including Europe), the Nearctic, the Neotropics, North Africa and East Asia. It is absent from the Near East. In Europe, it is found in Austria, the Azores Islands, Belgium, the Canary Islands, Cyprus, the Czech Republic, mainland Denmark, Finland (doubtful), mainland France, Germany, Great Britain including the Isle of Man, mainland Greece, the Republic of Ireland, mainland Italy, Malta, mainland Norway, Poland, mainland Portugal, northern Russia (doubtful), Sardinia, Slovakia, mainland Spain, Sweden (doubtful), Switzerland and the Netherlands.[1][2]

It is also known as the Powder Post beetle, due to leaving a pile of powder when boring into wood.[2]

Wood insect attack

It will attack the dry sapwood of dead woods of oak, chestnut, black locust, ash and elm, as well as some tropical timbers like obeche, although these become less susceptible with age, and by 15 years will no longer be attacked by it. All susceptible timbers have in common a high amount of starch and large pores. Softwoods are generally immune to the beetle. [3]
