| Milkweed | First, the Egg! | Caterpillars | Chrysalis | A New Beginning—the Butterfly | Off They Go to Mexico! |
In the fall, Monarchs leave milkweed fields in Canada and the United States and fly south into Mexico. They migrate to the mountains of Mexico, a journey of up to 2,200 miles or more. Hundreds, millions of these butterflies live between Canada and Mexico and make the trip. They fly about twelve miles per hour. It takes them two to three weeks to get to their destination. Along the way they eat nectar from flowers. Some die on their way there. Once they arrive, they roost in fir trees near Mexico City. They stay there over the winter. The butterflies are losing places to roost. The largest tract of Oyamel trees is about twenty square miles. That is five times smaller than the largest tract of trees was just fifteen years ago.
