Flight of the Butterflies is a Canadian documentary film directed and co-written by Mike Slee for IMAX, starring Megan Follows, Gordon Pinsent, and Shaun Benson. The film covers Dr. Fred Urquhart's nearly 40-year-long scientific investigation into the monarch butterfly (Danaus plexippus), tracking the details of what is considered one of the longest known insect migrations - the flight of the monarch butterfly from Central Mexico to the United States and Canada and back.
