"Attributes of Pieris Brassicae." The subcostal black spot before the apex shows through from the upperside.
The hindwing is light ochraceous brown, closely irrorated with minute black scales. Caterpillars from June to September. [16], These female butterflies oviposit in clusters on the undersides of leaves because the larvae prefer the morphology of leaf undersides over the upper surface of leaves.

[22][24] Aposematism is not entirely related to Müllerian mimicry; however, large white larvae often benefit from multiple other aposematic larvae from other species, such as the larvae of Papilio machaon.
