Figures 5.10. The generalized structure of a libelluloid dragonfly egg (Odonata: Corduliidae, Libellulidae).

Libelluloid dragonflies oviposit into freshwater but always exophytically (i.e. outside of plant tissues). The endochorionic and exochorionic layers of the eggshell are separated by a distinct gap in some species. A gelatinous matrix may be present on the exochorion or as connecting strands between eggs.
