Vanessa es un género de mariposas ninfálidas. El nombre se ha sugerido que es una variante de Phanessa, una palabra griega para una divinidad mística. El nombre de la divinidad en realidad no es Phanessa, sino Fanes. Johan Christian Fabricius, el entomologista que nombró a este género usaba los nombres originales de las divinidades clásicas cuando creaba nuevos nombres científicos.

The Agathina Emperor (Doxocopa agathina) is a species of butterfly of the Nymphalidae family. It is found in the Guyanas, northern Brazil, and the Amazon region. It is also called the Purple Emperor but this name also refers to the European butterfly Apatura iris.

The color of the wings varies by sex. Males have bright blue or purple wings, but the females' wings are darker in color, usually shades of brown. Females also typically have a diagonal orange band across their forewings. In both sexes, the wingspan measures about 50 millimetres (2 inches).
