The Magic of Monarch Butterflies

Monarch butterflies are famous for their long journey. Every year, millions of them fly from Canada and the US to Mexico—over 4,000 kilometers! But why do they travel so far?

Part 1: The Great Migration

Monarchs can’t live in cold winters. So they fly to warm Mexico, where they rest in huge groups on tree branches. These groups look like orange clouds! The trip takes about two months, and not all butterflies survive.

Part 2: A Dangerous Journey

Today, monarchs face trouble. Their favorite food, milkweed plants, are disappearing. Farmers use chemicals that kill milkweed. Also, climate change makes the weather unpredictable.

Storms can hurt the flying butterflies.

Part 3: How to Help

People are taking action. Many plant milkweed in their gardens to feed monarchs. Schools also teach students about the butterflies’ journey. In Mexico, workers protect the forests where monarchs rest.
