The mature larvae of eight Phyllobius species are described using advanced optical methods. The larvae of P. pomaceus Gyllenhal, 1834, P. pyri (Linnaeus, 1758), P. virideaeris (Laicharting, 1781), and P viridicollis (Fabricius, 1792) are re-described, and the mature larvae of P. arborator (Herbst, 1797), P. argentatus (Linnaeus, 1758), P. maculicornis Germar, 1824, and P. roboretanus Gredler, 1882 are described for the first time. In P. viridearis only an unillustrated description was available. A key including other species of the genus Phyllobius with sufficient description is given. We used our data and from the literature as well to review and update two special features of Phyllobius biology: the general life cycle and aspects of host plant use and vertical distribution of selected Phyllobius species. Keywords. Phyllobius, Central Europe, weevil biology, illustration, key, bionomics, larvae biology. Introduction In this contribution about premature stages of Central European Entiminae we deal for the first time with larvae of the genus Phyllobius Germar, 1824 from the tribe Phyllobiini.
