The mature larva of the weevil species (Linnaeus, 1758), one of only two Palaearctic members of the supertribe Orobitiditae, is re-described, while the pupa is described for the first time. The biology of this species was studied at two sites in Germany. It was reared from seed capsules of L. (Violaceae), and feeding holes were observed on Rchb. Adults of and Reitter, 1885, specialists of , show a well-developed escape mechanism, to which contribute a smooth surface, a rounded, nearly spherical body shape, and a seed-imitating thanatosis behaviour. The molytine weevil (Gyllenhal, 1834), the only other known weevil specialist of in Europe, has a smooth surface, also, and is the most spherical species of the genus. The unique characters of the larva and pupa of are discussed in regard to the systematic position of this taxon.
象鼻虫物种(林奈,1758年)的成熟幼虫被重新描述,它是超族Oorbitiditae仅有的两个古北区成员之一,而蛹则是首次被描述。该物种的生物学特性在德国的两个地点进行了研究。它是从L.(堇菜科)的种子荚中饲养出来的,并且在Rchb.上观察到了取食孔。1885年的 和Reitter的成虫,作为 的专家,表现出一种发达的逃避机制,其光滑的表面、圆形的近乎球形的体型以及模仿种子的假死行为都对此有贡献。欧洲另一种已知的象鼻虫专家——molytine象鼻虫(吉伦哈尔,1834年)也有光滑的表面,并且是该属中最呈球形的物种。根据这个分类单元的系统位置,讨论了 的幼虫和蛹的独特特征。
