ABSTRACT Many species of dragonflies exhibit sexual dimorphism and biased sex ratios in adult populations. It is predicted that, in species with territorial adults, males should be larger than females at emergence. Larger male size should elevate foraging rate and lead to increased predation risk and higher male mortality during the larval stage. We tested these predictions for a territorial dragonfly, Anax junius, using laboratory and field experiments. We measured differences in growth and… CONTINUE READING
