Millions of Monarchs Swarm Fake Hummingbird As It Captures Spectacular Footage of Their Flight

With its clementine-colored wings bordered with black lines and white spots, the monarch, also known as Danaus Plexippus, is a widely recognizable insect. As the weather changes and gets cooler, the monarchs migrate from their breeding grounds in Canada and the northern United States and fly to central Mexico, where they form clustered colonies on oyamel fir trees to conserve heat until the days grow longer and they migrate north once again. 

In this spectacular clip filmed by the PBS series Spy in the Wild, a mechanical “spy hummingbird” flies over a swarm of resting monarchs. Creators chose the flying creature because it feeds on nectar and thus isn’t seen as a threat. As the sun warms the butterflies’ wings to 50 degrees, the insects wake and start to flutter and move. The hummingbird spy finds itself within the very heart of the swarm and captures a spectacular scene in which millions of butterflies take to the sky once more in a mesmerizing confetti-like cloud.
