About Apoderus coryli (C.Linnaeus, 1758)
Apoderus coryli (C. Linnaeus, 1758), a primitive weevil, has an adult body length of 6–8 millimetres (0.24–0.31 inches). Adult individuals have a shiny red bell-shaped pronotum, a shiny black or dark brown head with protruding eyes, a distinct neck, and short rounded elytra. Their straight antennae are inserted close to the base of the rostrum. The prothorax is significantly narrower than the base of the elytra on the abdomen. The scutellum is broad, shaped from triangular to trapezoidal, and has no stripes. Adult legs are red at the base and black toward their ends.
Mature larvae of this species reach an approximate body length of 10 millimetres (0.39 inches), and are bright orange with a brown head. Pupae are also orange, and measure about 6–8 millimetres (0.24–0.31 inches) in length.
This species is quite similar to the oak roller weevil (Attelabus nitens) and Apoderus erythropterus, the latter of which has a black pronotum. All three species create leaf wraps to hold their eggs.
This weevil is widespread across most of Europe, including Albania, Austria, Belarus, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Luxembourg, Slovakia, and the United Kingdom. It is also found in the eastern Palearctic realm (China and Japan) and the Near East.
Apoderus coryli inhabits deciduous forests, particularly forest edges, as well as parks and gardens, where its host plant Corylus avellana grows.
