The Monarch butterfly's incredible migratory journey

A butterfly weighs just about half a gram and yet this lightweight delicate creature plays a key role in keeping the ecosystem intact. Millions of Monarch butterflies migrate from the Northern hemisphere to Mexico for the winter. This natural spectacle draws thousands of visitors. But the butterflies aren’t just a tourist magnet. They help the farmers in the region by helping to pollinate their plants. In addition, the Mariposa Monarca biosphere reserve, where the butterflies live, helps secure the drinking water supply for Mexico City.
