Ontogeny of sexual size dimorphism revisited: females grow for a longer time and also faster
Original language description
Sex-specific mechanisms of the determination of insect body sizes are insufficiently understood. Here we use the common heath moth, Ematurga atomaria (Lepidoptera: Geometridae) to examine how larval growth trajectories differ between males and females. We monitored the development of 1379 larvae in controlled laboratory conditions. Sexually dimorphic development times during the first four instars were associated with sexual size dimorphism (SSD) in the beginning of the fifth (last) instar, when females were on average 15 percent heavier than males. Similarly, the duration of the last instar was about 13 percent longer in females. Further, we specifically focussed on the estimates of differential (instantaneous) growth rates of the larvae based on 24h mass increments of the 2nd, 3rd, 4th and 5th day in the beginning of the last instar. We calculated allometric differential growth rates as the per-day increase in cube-root-transformed mass of the larvae. We found that allometric growth rate
