Monarch Butterflies. They’re on their way south; passing through South Carolina right now. They summer in the U.S. and Canada. They winter as far south as the northern part of South America. Most Monarchs don’t live very long, not nearly long enough to migrate thousands of miles, so they do it over successive generations. It takes three or four generations to migrate north, then a longer lived version migrates all the way back south in one generation. Imagine that; an animal that not only migrates great distances, but does it as a cooperative effort between generations.
