The tawny emperor is a medium sized, non-descript butterfly that is common in riparian forests, but is also found in dry woods and suburbs. Larvae that develop in fall overwinter in small groups in a hibernaculum constructed by tying leaves together with silk so it stays on the tree throughout the winter.
