Effects of developmental temperature (a-e) and development time (f-j) on the first principal component (PC1) of nine ventral wing pattern elements, explaining about 60% of the variation in eyespot and band size in each species. Coloured dots represent the values for individuals reared at 21 °C (blue), 23 °C (light-blue), 25 °C (pink) and 27 °C (red). In graph f, a linear regression line was fitted and explained about 55% of the variation. In graphs g-j, piecewise linear regressions were fitted and explained over 60% of the variation in all species. The filled symbols indicate the significant inflection points, the secondary inflection point in M. mineus, indicated by an open symbol, was not significant
