20. Green Darner Dragonfly
The green darner dragonfly is a tiny but mighty traveler, migrating thousands of miles across North America each year. Scientists believe these dragonflies rely on a combination of polarized light, prevailing winds, and geomagnetic cues to navigate their impressive journeys. Despite their delicate appearance, green darners complete epic migrations that rival those of much larger animals, demonstrating the extraordinary adaptability and navigational prowess found in the insect world.
