Lepidoptera
- At first glance, the monarch butterfly seems built for beauty, not endurance. Its paper-thin wings look like they could tear in a strong breeze, and its delicate body appears better suited for floating between flowers than crossing continents. Yet these seemingly fragile creatures pull off one of nature's most incredible feats: a 3,000-mile migration. Just like geese, caribou, and senior citizens, they undertake this migration to avoid the harsh winters of the north.
