Relationship between larval mass at 21 days of development (mg) and the day on which the egg was laid. Larvae had mothers that either had been forced to fly or were controls as indicated. For each of these two groups the linear relationship between development time and day of oviposition is indicated as modelled in the random slope lme model (see text). Full random slope lme model fitted was: √(larval mass at 21 days of development) = egg size + day of oviposition + flight treatment + flight treatment*day of oviposition.
