The United Nations Educational, Scientific and Cultural Organization (UNESCO) named eight new sites to the World Heritage list yesterday and Mexico’s Monarch Butterfly Biosphere in Michoacan is among them. The biosphere is famous for the estimated 150 million monarch butterflies that migrate every fall from Canada creating a beautiful, orange, flowered effect on the trees there that actually bend under the weight of so many winged insects. But what’s most interesting to us is that scientists have no idea how the little buggers find their way across North America to Mexico every year. It’s okay, the Department of Homeland Security can’t figure that sort of thing out, either. Just chalk it up to a God-given, Mexican, internal compass. After the jump, seriously “aw” worthy moments from the reserve caught on video.
