How does the monarch butterfly deal with the winters in north America?

Monarch Butterflies migrate thousands of miles to escape the cold winters in North America, primarily traveling to central Mexico where they find a suitable climate. During this migration, they rely on specific environmental cues, such as temperature and daylight, to time their journey. In their wintering grounds, they cluster together in large groups to conserve warmth and reduce energy expenditure. This remarkable adaptation allows them to survive the harsh winter months until they return north in the spring.
