Dragonflies and damselflies are ancient creatures that have lived on Earth far longer than mammals. They have sophisticated eyes, over twenty to thirty thousand per head. Dragonflies are fast fliers; the blue-eyed darner can fly 48 feet per second while chasing prey. Most can fly far, even able to survive crossing a sea or ocean, if they have to.
