Odonata is an order of insects that includes the highly diverse and visually striking groups known as dragonflies and damselflies. These insects are characterized by their elongated bodies, two pairs of strong, transparent wings, and excellent flying capabilities. They are primarily aquatic during their nymph stage and are important predators both in their larval and adult forms, playing vital roles in ecosystems by controlling mosquito populations and serving as indicators of environmental health.
Key Features
