Summer is coming to a close, but we have something special to enjoy, observe and celebrate. Mid-August marks the start of fall migration for millions of monarch butterflies. Adult monarchs are partway through their lifecycle, but their reproduction is on hold. These monarchs are different from their parents, grandparents and even great grandparents. Previous generations completed their life cycle in four weeks. Each of these previous generations migrated north, resulting in four generations over the course of the summer. Butterflies in this last generation are members of the generation that migrates south, often called the monarch super generation.
