Dragonflies and Damselflies

Odonata is an order of predatory flying insects that includes dragonflies (Anisoptera), damselflies (Zygoptera), as well as the three relict species of damsel-dragonflies (Anisozygoptera), the latter two often grouped together. These groups are distinguished by the bulkier build, larger, usually contiguous, compound eyes, and, a typically horizontal resting position of wings of dragonflies, and by the slender body, smaller, laterally-placed eyes, and, a typically closed resting position of the wings of damselflies. Intermediate characters are found in damsel-dragonflies (Epiophlebia). Adult odonates can land and perch, but, contrary to myth, can also rarely walk.

Almost all odonates have aquatic nymphs called naiads, and all of them, juveniles and adults, are carnivorous, the latter almost entirely insectivorous, though nymphs will eat anything that they can overpower, including small fish, tadpoles, and even adult newts. The adults are superb aerial hunters and their legs are specialised for catching prey in flight.
