Description: Monarch butterflies cluster in :Santa Cruz. Monarch butterflies migrate to Santa Cruz to spend a winter. During migration Monarch butterflies travel up to three thousand miles. No other butterflies migrate like the Monarchs of North America. Even more amazingly, the butterflies that make the journey are the great-great-grandchildren of the butterflies that left the migration place the previous spring, yet somehow they find their way to the same roosting spots, sometimes even the same trees.
