FW with Cu appearing 3-branched, R 3- or 4-branched (5-branched in some orange-tips), and Mi stalked with a branch of R for a distance beyond discal cell.

Whites are white with black markings. Our most common species is the Cabbage Butterfly (see also p. 219), Pieris rapae (Linn.); its larva feeds on cabbage and related plants, and is a serious pest of cabbage. Sulfurs (Pl. 9) are yellow or orange, and our most common species have the wings bordered with black; some sulfurs are very common butterflies; larvae of the common species feed on clovers. Orange-tips are small white butterflies that have underside of the wings mottled with greenish, and tips of the front wings are often orange; they are relatively uncommon, and most species are western; larvae feed on shepherd's purse and related plants.
