Dragonfly-DYK

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.
