The Incredible Navigation Skills of Monarch Butterflies

The monarch butterfly is a marvel of the natural world. Every year, millions of these delicate insects travel up to 3,000 miles from North America to a specific group of forests in Mexico. What’s astonishing is that no single butterfly completes the entire round trip. It takes four generations to make the journey. So how do they know where to go? Scientists believe they use a combination of a sun compass in their antennae and an internal magnetic compass. This genetic GPS is one of the most fascinating examples of instinct in the animal kingdom, proving that you don’t need a big brain to be a master navigator.
