Morphology
The Pieridae have the radial vein on the forewing with three or four branches and rarely with five branches. The forelegs are well developed in both sexes, unlike in the Nymphalidae, and the tarsal claws are bifid, unlike in the Papilionidae. Like the Papilionidae, the 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. But some species such as the madrone butterfly that belong to this family do not shows the presence of this abdominal silk girdle.
