Introduction Butterflies have intrigued people for centuries, and few species are as bewitching as the monarch. Admired throughout history for its graceful flight and vivid orange-and-black markings, it is celebrated today for an astonishing feat: A single monarch may travel as many as 3,000 miles—from Canada to Mexico—during its annual fall migration. It is the only butterfly known to migrate north and south as birds do.
