Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Damselflies live for 2 months to 3 years as nymphs, undergoing five to 15 molts as they grow. At this stage, naiads like the adults, are fierce predators. They prey on freshwater organisms, mosquito larvae, various small aquatic insects and other arthropods within their reach
