Loss of wetland habitat threatens dragonfly populations around the world.ĭragonflies are predators, both in their aquatic larval stage, when they are known as nymphs or naiads, and as adults.

Most are tropical, with fewer species in temperate regions. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each.įossils of very large dragonfly ancestors in the Protodonata are found from 325 million years ago (Mya) in Upper Carboniferous rocks these had wingspans up to about 750 mm (30 in). Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight. Dragonflies can be mistaken for the related group, damselflies (Zygoptera), which are similar in structure, though usually lighter in build however, the wings of most dragonflies are held flat and away from the body, while damselflies hold the wings folded at rest, along or above the abdomen. Adult dragonflies are characterized by large, multifaceted eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Our services range from product training to custom development and our software is deployed by registered users in more than 80 countries.A dragonfly is an insect belonging to the order Odonata, infraorder Anisoptera (from Greek anisos, 'unequal' and pteron, 'wing', because the hindwing is broader than the forewing).
