AbstractPieris brassicae was very abundant in the UK in 1992. The timing of systematic counts, anecdotal reports of exceptional local abundance and frequent counts at a coastal site, cast doubt on the importance of immigration in contributing to the large populations. Emergence within the UK is suggested.
