The wingspan is 53–77 mm (2.1–3.0 in). Males are solid white on both the upper and lower surfaces of the wings except for a narrow edging of black along the forewing costal margin. The female has two forms: the dry-season form is all white and the wet-season form has black along the forewing costal margin and a yellow-orange upper hindwing. The dry-season form is on wing from October to April and the wet-season form from May to September. They feed on flower nectar from a variety of weeds and garden plants including Lantana and Eupatorium.[2]

The larvae feed on Brassicaceae species, including Drypetes lateriflora and Capparis flexuosa in Florida. They are shade loving and feed during the night and on cloudy days.[2]
