Butterfly migration is a phenomenon where butterflies travel long distances during certain times of the year. They migrate for various reasons, such as to find suitable breeding grounds, avoid harsh weather conditions, or seek better food sources. The most well-known example of butterfly migration is the Monarch butterfly, which travels thousands of miles from North America to Mexico for the winter. Researchers study butterfly migration patterns, routes, and behavior to better understand the ecological and environmental factors that influence this fascinating natural phenomenon.
