Odonata (Dragonflies and damselflies)
The order Odonata includes dragonflies and damselflies.
The Order Protodonata includes the largest insects in Earth history. The order became extinct at the end of the Permian period (251 million years ago). Wingspan was up to 75 cm and looked very similar to dragonflies, but with more primitive wings compared with the odonatans, which are thought to be their descendants.
