Common green darners are among the largest of the dragonflies of our area, having a wingspan up to 4.5 inches. Their large and complex eyes give them the good vision they need to hunt on the wing, capturing other flying insects like wasps, mosquitoes and other dragonflies. They live in the water several years as nymphs (immature forms) where they hunt tadpoles and other aquatic insects. When mature, the large nymphs (about 2" long) crawl up onto the stems of water plants, and emerge as adults from their final nymphal exoskeleton. While some over-winter as aquatic nymphs, some adults also migrate, using the same migratory routes as song birds and raptors. In fact, they often become a food item for migrating American kestrels and merlins.
