Mature larva and pupa of (Olivier, 1807) (Curculionidae: Lixinae: Lixini) are morphologically described for the first time and compared with known larvae and pupae of other species. Very high counts of larval body setae (pronotum with more than 25 setae and postdorsum on meso- and metathorax and also on abdominal segments I-VII with more than 12 setae) are characteristic features of the nominotypical subgenus Larinus. The biology of the species was studied in Ukraine. and were identified as host plants of both larvae and adults of this weevil based on the present research in Ukraine, which shows probably oligophagous. Overwintering beetles emerged at the end of May or earlier, then feeding and mating on the host plants. The highest level of adult activity was observed at the end of June. Larvae were endophagous within the flower heads. In July and August, the larvae pupated within inflorescences in a pupation cell. Adults exited the cells at the end of August and did not hibernate on the host plants. Sometimes, larvae and imagines of a new generation were found outside the flower heads in chambers constructed on the stems.
首次对（Olivier，1807）（象甲科：根瘤象亚科：根瘤象族）的成熟幼虫和蛹进行形态学描述，并与其他根瘤象物种已知的幼虫和蛹进行比较。幼虫体表刚毛数量非常多（前胸背板有超过25根刚毛，中胸和后胸以及腹部第一至七节的后背有超过12根刚毛）是指名亚属根瘤象的特征。在乌克兰对该物种的生物学特性进行了研究。根据乌克兰目前的研究，确定[具体植物名称1]和[具体植物名称2]是这种象甲幼虫和成虫的寄主植物，这表明其可能为寡食性。越冬甲虫在五月底或更早出现，然后在寄主植物上取食和交配。在六月底观察到成虫活动最为频繁。幼虫在花头内取食。七月和八月，幼虫在花序内的化蛹室中化蛹。成虫在八月底离开化蛹室，不在寄主植物上过冬。有时，新一代的幼虫和成虫在茎上建造的腔室中的花头外被发现。
