About the Hazel Leaf-Roller Weevil

Apoderus coryli, the hazel-leaf roller weevil, is a species of leaf-rolling beetles belonging to the family Attelabidae subfamily Attelabinae. Because of the trunk-like elongated head, it is often mistakenly attributed to the weevil family Curculionidae.

This species is widespread in most of Europe (Albania, Austria, Belarus, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Luxembourg, Slovakia, United Kingdom), in the eastern Palearctic realm (China and Japan), and in the Near East.

Apoderus coryli prefers deciduous forests, especially at forest edges, but also parks and gardens where the host plant, Corylus avellana, occurs. Apoderus coryli can reach a length of 6–8 millimetres (0.24–0.31 in). These primitive weevils have a red shiny bell-shaped pronotum, a shiny black or dark brown head with protruding eyes, a distinct neck and short and rounded elytra. Their straight antennae are inserted near the base of the rostrum. The prothorax is much narrower than the base of the elytra on the abdomen. The scutellum is broad, triangular to trapezoidal and without stripes. The... Wikipedia →
