Effects of forewing melanisation plasticity (‘plasticity’), melanin proportion (‘melanin’), sex, mating and rearing temperature on lifespan in Pieris brassicae: results of model averaging on linear mixed models with family as a random effect.

Plasticity is estimated by the variance of forewing melanisation between temperatures (a) and the absolute slope of the thermal reaction norm (b). Females were taken as references for the calculation of coefficients. Significant variables (p0.60 are bolded. SE stands for the standard error.
