We analyzed several species of the weevil family Mecininae (Coleoptera, Curculionidae) that all feed on iridoid glycoside (IG) containing plants of the Plantaginaceae to investigate whether the beetles sequester these deterrent substances from their host plants. Within the Mecininae two genera of the tribe Cionini were found to sequester aucubin and catalpol:CionusClairvilleandSchellenbergandCleopusDejean. Both analyzed genera of the Mecinini,MecinusGermarandRhinusaStephens, do not sequester IGs although the compounds are present in their food plants. They thus represent the first case of specialists on IG plants that have not evolved adaptations to use the compounds. However, in contrast to the Cionini these genera have a hidden lifestyle, so that their need for defence might be lower. BothCionusandCleopus, sequester catalpol with a higher efficiency than aucubin. However, in contrast toCionusspecies,Cleopusspecies only sequester catalpol. In species feeding onScrophularia, the aucubin concentration is higher while in beetles onVerbascumcatalpol is usually dominating. This pattern can also be detected in the only species living on both plants,Cionus hortulanus. The ability to sequester IGs must have a single origin at the base of the sister generaCionusandCleopus.
