Monarch butterflies are relatively small insects that participate in one of nature's most impressive migrations, but many scientists and other professionals are concerned about their long-term survival.
The butterflies can travel from their wintering grounds in central Mexico to summer homes in the United States and Canada. However, their descendants eventually return to Mexico to begin the process again.
