Around 200 species of butterflies and moths migrate. That means they move from one area to another. Some of them migrate to escape cold weather. Others migrate because it’s too crowded where they’re living.
No other insect migrates as far as the North American monarch butterfly. They migrate because they can’t survive winter. Monarchs travel more than 2,000 miles each year from Mexico (and California) to Canada and back. No one monarch makes the whole trip. Instead, the migration is like a relay race. Parents start the trip, and their children finish it.
