Monarch butterflies, instantly recognizable for their gold and black markings, are found in many places around the world. But only those east of the Rocky Mountains in North America make the longest annual insect migration. From their summer habitats in the north, every autumn 300 million butterflies fly south — more than 5,000 kilometers — to a few small forests in Mexico. And that’s the path that this unusual ultra-light aircraft will follow this year — piloted by a crew of documentary filmmakers, including lead pilot Francisco Gutierrez.
