monarch with a full tank can carry 140 mg of fuel. When it flies without
flapping it can travel 1,060 hours on that single tank of fuel.
contrast, when a monarch flaps its wings it burns its fuel quickly.
When it flies its fastest a monarch flaps up to 12 times every second!
This fast flight is called “escape flight.” A monarch
burns 12.7 mg of fuel every hour during escape flight.
this monarch math. You’ll see why soaring, gliding and riding
with the wind are so important to migrating monarchs:
