Watch the story of the “wandering glider” dragonfly. These tiny two-centimetre long insects, begin their journey in India. They fly thousands of feet in the air and ride the rain clouds all the way to Africa. Not only is this the greatest migration of any insect–even longer than the Monarch butterfly–it has profound consequences for both continents.
