Apoderus coryli, common name hazel-leaf roller weevil, is a species of leaf-rolling beetles belonging to the family Attelabidae subfamily Attelaninae. Because of the trunk-like elongated head, it is often mistakenly attributed to the weevils. == Description == ''Apoderus coryli'' can reach a length of . 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 legs are red at the base, black towards the end. Adults can be found between May and September. They feed on leaves of the host plant, the hazel (''Corylus avellana''), hence the Latin name ''coryli'' of the species, meaning hazelnut. Only in exceptional cases other deciduous trees, such as alder and birch, are used as host plants.
