Pieridae
Pieridae (whites and sulfur)
The Pieridae is a large family of nearly 10,000 species contains some of the most abundant and familiar butterflies, several of which are notorious pests of agriculture. In the majority of species the ground colour of the wings is either white or yellow, but there are some notably colourful exceptions, especially the jezebels from the Indo-Australian region. Both sexes walk on all six legs, which end in four tiny forked claws, while the inner margins of the hind wings form a kind of channel into which the body makes a neat fit. Many species are noted migrants.
Pieridae eggs are generally spindle-shaped, being taller than they are wide, and the female carefully places each egg on end upon the foodplant. The caterpillar are rather smooth and featureless, often greenish, in some species living alone and in others forming large aggregations. The chrysalis is fastened down by a special tail-hook (cremaster), with the additional security of a silken girdle placed around its middle.
