The Bath White complex has been split into two species in the 1980s, P. daplidice (LINNAEUS, 1758), which mainly occurs in the Western Mediterranean, and P. edusa (FABRICIUS, 1777), which is distributed over the rest of Europe. However, these two species cannot be distinguished in the field. Their life cycles are also very similar. The adult butterflies are very mobile, fast flying and migrate northwards and westwards in warm years. They occur in warm, stony places; often disturbed ground, such as road verges, abandoned agricultural land or quarries. The females lay their eggs on such crucifers as mustards (Sinapis spp.), Alyssum spp., and also on mignonettes (Reseda spp.). The caterpillars feed mainly on the flowers and seeds. Pupation takes place on the stalk of the foodplant. These species have two or more broods a year and hibernate as pupae.
