a Scatter plot of body volume at larval stage entry vs. added body volume per larval stage for each individual. Red circles: binned average along x-Axis. red line: robust linear regression (thick) with 95% confidence intervals (thin). Data is shown as relative deviation to the batch mean. Rare outliers beyond the +/− 20% range are omitted for clarity. Value above chart indicates slope of regression line +/− 95% CI. Color code indicates point density. b As (a), but for pharynx volume. c Absolute rate of body (top) and pharynx (bottom) volume growth as a function of larval stage progression. Individuals were binned into 10 classes according to their volume at 40% of each stage (red is the smallest volume, blue the largest volume). Individuals were re-scaled from moult to moult before averaging. The drop in growth rate at 80–90% of the larval stage represents the growth halt during lethargus. a–c n = 475, 641, 641, 638 individuals for L1 to L4 from m = 4 day-to-day repeats.
