Reaction norms for egg size in relation to LARVAL rearing temperature in the butterfly, Bicyclus anynana. Each line connects the mean egg size of females reared at 20°C with the mean egg size of their sisters reared at 27°C, and thus represents a single split-family. The two graphs refer to parental generation females transferred as pupae to 20°C (a) and to 27°C (b). As offspring, ADULT temperature did not affect egg size, these treatments were pooled.
