- from Butterflies & Moths
About 200 species of butterflies and moths migrate. That means they move from one area to another. Some migrate to escape cold weather, while others migrate to escape overpopulation.
North America’s monarch butterfly is the champion of insect migration. But, unlike all other butterflies and moths in regions with nice weather, monarchs migrate because they can’t survive winter. Monarchs travel more than 2,000 miles each year from Mexico (and California) to Canada and back. Yet no one monarch makes the entire trip. Instead, the migration is like a relay race. Parents start the trip, and their children finish it.
