Apoderus coryli length of about . This species is rather similar to the oak roller weevil ("Attelabus nitens") and "Apoderus erythropterus", that shows a black pronotum. All three species produce leaf wraps into which the eggs are laid. 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 ("Alnus" species), birch ("Betula" species), common hornbeam ("Carpinus betulus") , common beech ("Fagus sylvatica") and hop-hornbeam ("Ostrya carpinifolia") are used as host plants.

Cepaea sylvatica Cepaea sylvatica " Cepaea sylvatica" is a medium-sized species of air-breathing dextral land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. It is a close relative of the grove snail ("Cepaea nemoralis"). This species lives in many of the same habitats as "Cepaea nemoralis", such as woods, dunes and grassland, however "C. sylvatica" tolerates wetter and colder areas than the grove snail can tolerate. "Cepaea sylvatica" is generally similar in appearance to "C. nemoralis", although the shell is not as colorful and not as variable as that of the grove snail. Also, the diameter of the shell of
