Odonata is an order of carnivorous insects, encompassing dragonflies (Anisoptera/Epiprocta) and damselflies (Zygoptera). The word dragonfly is also sometimes used to refer to all Odonata, but odonate is a more correct English name for the group as a whole. Odonata enthusiasts avoid ambiguity by using the term true dragonfly, or simply Anisopteran, when referring to just the Anisoptera. The term Warriorfly has also been proposed. Some 5,900 species have been described in this order.
