Butterflies are free. Monarchs may arrive at their winter home late, be choosy about where to land, and may leave early. At around 10,000 feet, the dormant volcanic peaks are covered in trees and flowers, with the specific temperatures the Monarchs need. Despite the distance and dangers, the fragile butterflies still manage to fly from Canada to Mexico every year in an extraordinary migration, one of the coolest natural events on earth.
Everyone loves the monarchs, and between the states of Mexico and Michoacán the reserve is both a UNESCO Biosphere and a World Heritage Site. During the November to March season, crowds of locals take bus day trips to see them fly, cluster, feed, mate and fly again. Since the flighty monarchs are unpredictable, day trips can visit their chosen forest at the best times. Overseas visitors often stay for a few days in lovely spots—like Cerro Pelón B&B run by a family of original butterfly rangers—to enjoy the picturesque villages and relaxing environment while recovering from high altitude hiking, as I did.
Humans can impact these glorious butterflies in many ways, both positively and negatively, and we need to be much smarter about making small changes that can help: reduce pesticides, grow butterfly friendly plants and drive slower when butterflies are present. But also, we need to make big, global changes to reduce our carbon emissions, so that this species can survive.
Which brings me to an Earth Day question. Is it worth flying and driving here to see the butterflies, knowing that your carbon pollution will contribute to their extinction? Better to drive an electric car.
