Imagine tiny, lemon-yellow butterflies fluttering their way across the globe over 26 million years—without GPS, airplanes, or even a consistent body shape. That’s the mind-blowing journey of the Eurema butterflies, as revealed by a new study. These unassuming tropical insects have quietly pulled off an evolutionary odyssey, adapting and spreading across continents in ways scientists are just beginning to unravel.

Editor’s Note: This isn’t just a cool butterfly fact—it’s a window into how life persists and thrives against staggering odds. The Eurema story challenges our assumptions about migration, adaptation, and even what "ordinary" species are capable of over deep time. For biologists, it’s a reminder that evolution’s greatest adventures might be hiding in plain sight. For the rest of us? Pure wonder.
