Ocean-Crossing Dragonflies Discovered

Posted by samzenpus on from the incredible-journey dept.

grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

    True but at least in the case of the sailplane (or albatross) you need control authority to steer out of sink and into lift which does take energy. In the case of an insect I can't see it having sufficiently low drag to take advantage of lift. To do that you need to be able to put your nose down and fly out of sink sometimes.
