Large White (Pieris brassicae) | |||||||||
Description | |||||||||
Wing span: 59-67 mm. This species is one of the two known as the "Cabbage White". Its larvae can reach pest proportions, and decimate cabbages (and other brassicas) to the point that the leaves become skeletons of their former selves. It occurs throughout the British Isles. The population is regularly augmented by migrants from the continent. The Large White can be seen almost anywhere, but is most numerous around fields of brassica crops, allotments and gardens. | |||||||||
