(1) Data on changes in numbers of thirty-one species of butterfly in Britain, in 1976-86, were used to investigate associations between relative abundance and weather by standard multiple regression. (2) The most striking association was between increased numbers and warm, dry summers. There was also a frequent association between wet conditions early in the previous year and increased numbers in the current year. Winter temperature and rainfall showed no strong associations with numbers of butterflies.
