Charles Anderson descopera libelule care traverseaza oceane

A humble dragonfly called the globe skimmer completes an astonishing 16,000-kilometer journey across the Indian Ocean every year, crossing vast stretches of open water where there is no freshwater for breeding. Despite their size, these insects ride high-altitude winds from India to Africa, synchronizing their migration with monsoon rains. This journey, accomplished over four generations, is twice as long as the famed Monarch butterfly migration. Birds like the Amur Falcon and Eurasian Roller follow the same transoceanic route, guided by the same seasonal winds and rains.
