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.

Luzula sylvatica grow on acidic soils in damp habitats. "L. sylvatica" can be found on stream banks and well-drained, open woodland, as well as in open ground and rock ledges and peaty heath moors. Despite its preference for acidic soils, it can tolerate most soil pH levels. The leaves of "Luzula sylvatica" are picked in winter by golden eagles to line their eyries. The flowers and seeds of "L. sylvatica" are also the sole food source for the larvae of the "Coleophora sylvaticella" moth. "Luzula sylvatica" is commonly used in horticulture — its thick, patch-forming habit (which allows the plant to act
