Every year, hundreds of millions of Monarch Butterflies from Canada and the United States journey as far as 2,500 miles to the forests of Michoacan, Mexico in what is known as the world’s largest insect migration. Countless butterflies cluster together both on the trees and on the ground, covering large areas into carpets of orange and black. It’s a breathtaking sight to behold, but as always, human greed is threatening to destroy it.
The great monarch migration is one of nature’s most fascinating mysteries. Tiny butterflies from places like Toronto, Winnipeg or Detroit embark on this epic transcontinental journey and somehow make it all the way to central Mexico. Nobody knows exactly how they do it, but some experts believe they are guided by celestial navigation and magnetic fields.
