Ecological Role - Dragonflies are carnivores, eating other animals. They are important predators in aquatic habitats in both the nymph and adult stages. They are fantastic fliers, able to swerve, dive, and quickly change directions to catch flying insects in mid-air. Birds, frogs, fish, and other dragonflies eat whitetail dragonflies.

Fun Facts - The whitetail dragonfly is one of the most common dragonflies in Kentucky. When the dragonfly sees its prey, it flies off of its perch and swoops like a hawk to catch it. It will then return to the same twig on which it was perched. The nymphs are somewhat tolerant of pollution and low oxygen levels, so they are considered biological indicators of pond health. Dragonflies of the Family Libellulidae are called skimmers because of the female’s egg laying habits, as described under Life Cycle.

Food - Flies, midges, ants, butterflies, and other insects
