Figure 5-2. Mass-specific intake (g dry mass/g*day) consumed by insects in each of five
 treatment groups on each day of the study. Curves were constructed by scaling the
 duration of each stage for each insect to the average duration of that stage for each
 treatment group and fitting a loess smoothing function to these data. Points where
 mass-specific intake declined to zero correspond to ecdyses. The first six resulting
 time intervals for each group represent juvenile stages and the seventh time interval
 for each group represents the adult stage. Arrowheads denote the average age at first
 oviposition for each group. Abbreviations: AL = ad libitum, R = restricted, juv. =
 juveniles, ad. = adults. See Figure 5-1 for a description of diet treatments. Food
 restriction was imposed by offering restricted individuals approximately 60% of the
 mass-specific intake of insects in group AL on a stage-specific basis. Because
 mass-specific intake of AL insects declined after first oviposition, the amount of food
 offered to food-restricted adults after first oviposition was decreased proportionally to
 match this decline.
