The 6 to 8 mm large hazel-leaf roller weevil Apoderus coryli (family Attelabidae) is the more common of the two species of the genus in Europe. The species is of east-palearctic distribution and ranges from Europe to the Near East. The beetle can be found from May to September on its host plant, the hazel (Corylus) in sparse deciduous forests and at the edges of forests. Based on size and thickness, the female selects a suitable hazel leaf and forms a cylinder or cradle during a few hours, which is used to deposit a single egg. The larva develops inside the cylinder, feeding on the leaf matter and finally pupates in the cylinder. Depending on the climate, there one or two generations per year. In Germany, Apoderus coryli is known to occur in virtually all Federal States and is regarded as not endangered. (CB)
