The common brimstone (Gonepteryx rhamni) is thought to be the original butterfly, named for the yellow colour of the male. It is a fairly large, pale yellow butterfly, with distinctive, leaf-shaped wings. Males have yellow wings and iridescence while females have greenish-white wings and are not iridescent. The common brimstone is found throughout the Palearctic.
