Biology and morphology of immature stages of Coniocleonus nigrosuturatus
Original language description
Mature larvae and pupae of Coniocleonus (Plagiographus) nigrosuturatus (Goeze, 1777) (Curculionidae: Lixinae: Cleonini) are described and compared with three other cleonine taxa with known larvae. The biology of the species was studied in Romania, Hungary and Slovakia. Common Stork's-bill (Erodium cicutarium) (Geraniaceae) is identified as a host plant of both larvae and adults of this weevil. The weevil is very likely monophagous, and previous records of thyme (Thymus sp., Lamiaceae) as the host planthence appear incorrect. Coniocleonus nigrosuturatus prefers dry, sunny places in grassland habitats, with sparse vegetation, bare ground and patchily growing host plants. Overwintering beetles emerge in early spring (March), feed and mate on the host plants. The highest activity of adults was observed from mid-April to mid-May. Larvae live in the soil in a vertical tunnel near the host plant and feed externally on the base of the stem. Usually, a single larva was observed at an attacked
