Classification
The Pieridae have the radial vein on the forewing with 3 or 4 branches and rarely with 5 branches. The fore legs are well developed in both sexes, unlike in the Nymphalidae, and the tarsal claws are bifid unlike in the Papilionidae.
Like the Papilionidae, Pieridae also have their pupae held at an angle by a silk girdle, but running at the first abdominal segment unlike the thoracic girdle seen in the Papilionidae.
