It was in grade school where I learned about the migration of the Monarch butterflies to Mexico, when millions and millions of butterflies fly along the Sierra Madre Oriental mountain range to spend the winter in Mexico. You would think they would go to the beach like ordinary people, but no, they stick it out in the mountains. There are years that due to climate change the temperatures dip below freezing in the mountains.
Did you know that the butterflies who make the trip are not the same butterflies who fly back? I was always under the assumption that they fly down and return home, and they don't. Somehow, I missed that part in school. There are 4 generations of butterflies among the ones who leave for Mexico and the ones who come back in the spring.
How do they find their way here when only their anscestors have been to Sacramento? You can read more in my personal blog today at this link: Why Not Travel to See the Monarch Butterflies in Mexico?
