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.

In some classifications, Hemitheini is reduced to subtribe rank as Hemitheiti.
