The male is the star attraction of this species of butterfly with its bright orange wing tips. The female, in contrast, is completely white with no orange but with distinctive black tips, in which it may be confused with other Pieridae (whites). The undersides of both sexes are mottled green and white which offers excellent camouflage when the butterfly is at rest. Wingspan up to 45mm (1 3/4in).
The caterpillars feed on Cuckooflower, Garlic Mustard, and Hedge Mustard. They are cannibalistic when young.
It flies March-July, and it is found in flower-rich habitats, especially woodland rides and clearings, hedgerows and damp meadows. Common and widespread throughout, except western Scotland where it is absent.
