The European beak or nettle-tree butterfly (Libythea celtis) is a butterfly of the Libytheinae group of the brush-footed butterflies family. Libythea celtis is found throughout southern Europe, northern Africa to western India and southern Russia. It is found in rural landscapes wherever its host plant Celtis grows. Adult butterflies hibernate, and females lay their eggs singly in the spring on the buds of the host plant.
