Migration of birds is a well known phenomenon. They travel south and keep themselves warm during the winter. Monarch butterfly is the only insect which mimics this behavior. They travel more than 2000 miles with their tiny wings and frail body. They park themselves in the mountains and settle down. Their heart rate slows down and they hibernate.
Once the harsh winter ends, these hibernating butterflies wake up and become active again. They start their journey northwards. They find a mate and lay eggs. From these eggs come out what are called first generation monarch butterflies. These in turn give birth to second generation monarch and so on. Finally, when it is winter, it is time to migrate.
The life span of a monarch butterfly is only 4-6 weeks. But, the monarch butterflies which hibernate to south live as long as 3-4 months in hibernation. Butterfly enthusiasts all over the world keenly follow the migration path of these monarch butterflies hoping to understand this puzzling activity of monarch butterfly migration.
