The development of sexual differences in body size in Odonata in relation to mating systems

European Journal of Entomology, 2007
Adult body size is the result of important environmental, maternal and/or genetic effects acting on animals during development. Here we investigate how sexual size dimorphism (SSD) develops in seven species of Odonata: Anax imperator, Cordulegaster ...

Material composition of the mouthpart cuticle in a damselfly larva (Insecta: Odonata) and its biomechanical significance [PDF]

Royal Society Open Science, 2018
Odonata larvae are key predators in their habitats. They catch prey with a unique and highly efficient apparatus, the prehensile mask. The mandibles and maxillae, however, play the lead in handling and crushing the food.

Species and life stages of Odonata nymphs sampled with large drift nets in two Wisconsin rivers [PDF]

, 2017
Because relatively few nymphs of Odonata are caught in most drift studies, they have been inconsistently reported and little is known about the species and life stages that are predisposed to drift.
