Flight of the Butterflies in 3D is an interconnected scientific adventure story that spans not only thousands of miles, but generations. It's about the remarkable Monarch butterfly migration, the most incredible migration on Earth, and the determined scientist who spent 40 years trying to discover exactly where the butterflies mysteriously disappeared when they flew south for winter. Dr. Fred Urquhart is the man obsessed with Monarchs. Along with his wife Norah, he founded the Insect Migration Association, enlisting thousands of volunteers across North America to tag hundreds of thousands of butterflies to track their migration route. Available in 2D and 3D.
