ODONATA Dragonflies and Damselflies
Forerunners of the Odonata Protodonata Paleodictyoptera
Forerunners of the Odonata Protodonata
Simplified Evolutionary History of the Odonata 300 200 100 Carboniferous Permian Triassic Jurassic Cretaceous Paleodictyoptera Protodonata Epiophlebioptera “Anisozygoptera” Anisoptera Zygoptera
Hexapod Orders Odonata Odon - tooth Number of Species >5000 Common names damselflies, dragonflies, skippers , darners Typical habitats Aquatic nymph, aerial adult Distinguishing characteristics • direct flight muscles • -wings can’t be folded Other features • nymphs with labial mask for prey capture • primitive wing venation - archedictyon

Odonata -Evolutionary History Meganeuropsis - Permian
Odonata - Adult modifications Modifications for a predatory life Well-developed mandibles Large eyes
Odonata - Adult modifications Modifications for a predatory life -orientation of thoracic segments -changed orientation of legs -spines on legs
Odonata - larval modifications Modifications for an aquatic predatory life Mouthparts palp submentum mentum prementum Larvae Hunting
Odonata - Classification - OLD -larvae with caudal lamellae -wings held vertically at rest -wings same size Zygoptera Odonata Anisozygoptera -larvae with no caudal lamellae -wings held horizontally at rest -wings different size Anisoptera
