''Asemum striatum'', the black spruce borer, is a beetle species belonging to the family Cerambycidae, subfamily Spondylidinae. This beetle is present in most of Europe, in East Palearctic ecozone, in the Near East, in Nearctic ecozone and in Oriental ecozone. The adults grow up to and can be encountered from May through August, completing their life cycle in two to three years. Head and pronotum are usually black, while elytrae are black or brownish, with various longitudinal ridges (hence the specific name). They are polyphagous in coniferous trees (mainly feeding on ''Pinus sylvestris'', ''Pinus mugo'' and ''Pinus nigra'', but also on ''Picea abies'' and ''Abies'' or ''Larix'' species). Larvae develop under bark of host plants, later in dead branches and stumps of trees. ==External links== * (Biolib ) * (Cerambycoidea ) * ( Cerambyx ) * (Fauna Europaea ) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Asemum striatum」の詳細全文を読む スポンサード リンク
