Aglais
Tortoiseshells
Aglais is a Holarctic genus of brush-footed butterflies commonly known as tortoiseshells. The genus contains several well-known European species including the small tortoiseshell (A. urticae) and the peacock butterfly (A. io). Taxonomic placement remains somewhat contentious, with some authorities treating Aglais as a subgenus of Nymphalis rather than a separate genus. Species in this genus are characterized by their distinctive wing patterns and adult hibernation behavior.
