Pieridae

Definition

A family of butterflies (order Lepidoptera) comprising approximately 1,100 species in ~76 genera, commonly known as whites, yellows, and sulphurs. Members are characterized by white, yellow, or orange wing coloration derived from uric acid-based waste pigments (pteridines and ommochromes), typically with black spotting. The family includes four subfamilies: Pierinae (true whites and sulphurs), Coliadinae (yellows and orange-tips), Dismorphiinae (mimic whites), and Pseudopontiinae (a monotypic African lineage). Pieridae are predominantly tropical but extend into temperate regions; many species are economically significant as crop pests (e.g., Pieris rapae, the cabbage white) or as model organisms for studies on wing pattern evolution, mimicry, and host-plant specialization.

Etymology

From Pieris (type genus, from Greek Pieris, a Muse) + Latin -idae (family suffix).

Example

The cabbage white butterfly (Pieris rapae), a widespread agricultural pest of Brassicaceae crops, belongs to the subfamily Pierinae within Pieridae.

Synonyms

• whites and yellows (informal)

Usage Notes

The common name 'whites and yellows' is often used for the family, though 'sulphurs' technically refers only to the yellow/orange Coliadinae. Pieridae is sometimes split into two families in older classifications (Pieridae sensu stricto and Coliadidae), but modern molecular phylogenetics supports a single family with four subfamilies. The family's distinctive pigment chemistry (waste-product-derived pteridines) is diagnostic and contrasts with the carotenoid-based colors of many other butterfly groups.
