Figure 5-1. Experimental design for Carausius morosus feeding trial. Lifespans are represented
 by horizontal bars divided into six instars and an adult stage. Time is not to scale, and
 differences in timing of life-history transitions between groups are not graphically
 presented. Vertical lines in juvenile stages denote ecdyses. White bars represent life
 stages when food was offered ad libitum (AL); shaded bars represent life stages when
 food was restricted (R) to 60% of the amount of food consumed by insects in group
 AL on a percent body mass basis. Insects in groups AL and R were maintained for the
 duration of their lifespans on ad libitum and restricted diets, respectively. Insects in
 the AL-R at 5th and R-AL at 5th groups experienced a diet switch on the first day of the
 fifth instar. Insects in the AL-R at Ov group experienced a diet switch at first
 oviposition. Because survival to first oviposition was extremely low for insects that
 were food-restricted for the duration of juvenile development, I was unable to test the
 effects of a diet switch from R to AL at first oviposition.
