The Nymphalinae are a subfamily of brush-footed butterflies. Sometimes, the subfamilies Limenitidinae, and Biblidinae are included here as subordinate tribe(s), while the tribe Melitaeini is occasionally regarded as a distinct subfamily. Their phylogenetics can be traced back to the Cretaceous Terrestrial Revolution after the Cretaceous-Paleogene (K-Pg) mass extinction, followed by repeated dispersals into the rest of the Old World and the New World during various periods beginning in the Eocene.
