Smithsonian.com has an article, entitled 14 Fun Facts About Dragonflies - http://www.smithsonianmag.com/science-nature/14-fun-facts-about-dragonflies-96882693/, which says, in part,

"6 ) Dragonflies are expert fliers. They can fly straight up and down, hover like a helicopter and even mate mid-air. If they can’t fly, they’ll starve because they only eat prey they catch while flying."
"8 ) The flight of the dragonfly is so special that it has inspired engineers who dream of making robots that fly like dragonflies."
"14 ) A dragonfly called the globe skinner has the longest migration of any insect—11,000 miles back and forth across the Indian Ocean."
