The white butterfly Pieris brassicae is a butterfly whose adult females lay their eggs on the leaves of cauliflower, cabbage, lettuce, broccoli, beetroot, spinach, and the larvae feed on them. Leafy vegetables are affected. Infestations are usually large, to such an extent that they may leave only the ribs.
