''Clytus rhamni'' is a species of ''round-necked longhorns'' belonging to the family Cerambycidae, subfamily Cerambycinae. This common beetle is present in most Southern Europe, in East Palearctic ecozone and in the Near East. The adults grow up to 6 – 12 mm and can be encountered from May through August, completing their life cycle in two year. The imagos fly the second year. Head, pronotum and elytra are brownish and the elytrae are crossed by light stripes, as this beetle imitates, for defensive purposes, like other species of the genus Clytus, the chromatic variety of wasps. Bicolor tibiae distinguish ''Clytus rhamni bellieri'' subspecies. They are polyphagous in deciduous trees. Larvae mainly feed in the dead wood of small branches of ''Rhamnus'' (hence the specific name), ''Castanea'', ''Quercus'', ''Ficus'', ''Ulmus'', ''Pyrus'', ''Prunus'' species. The adults are very common flower-visitors. ==Subspecies== *''Clytus rhamni bellieri'' (Gautier, 1862) *''Clytus rhamni rhamni'' (Germar, 1817) *''Clytus rhamni temesiensis'' (Germar, 1824) 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「Clytus rhamni」の詳細全文を読む スポンサード リンク
