This large species has very long legs and a strongly arcuate long beak. The pronotum and elytra are quite variable in granulation. The colour varies from pale to deeper tan or yellowish. The adults of these beetles can be found from January up to March. They have been reported breeding in bamboos. The females puncture the young shoots and lay one egg in each perforation. The larvae develop in the internodes of bamboos and are considered a pest of these plants. This species shows a striking sexual dimorphism. In fact the male and the female of this beetle were once believed belonging to different species (respectively to ''Rhinastus pertusus'' and ''Rhinastus sternicornis'', actually considered synonyms). ==Distribution== This species can be found in Brazil, Peru and Argentina. 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「Rhinastus sternicornis」の詳細全文を読む スポンサード リンク
