The Monarch's Long Journey

A monarch butterfly named Aurora sets off on one of the longest journeys any insect makes — thousands of miles to a forest in Mexico.

As the days grew shorter in a field in Canada, a monarch butterfly named Aurora felt something new: a strong, quiet pull toward the south.

Aurora had never been south. She had hatched just a few weeks earlier, crawled out of her chrysalis, and spent her days sipping nectar from purple asters. But somehow she knew exactly which way to fly.

Monarchs born in late summer are different from the ones born in spring. They are a special "super generation." Instead of living only a few weeks, they can live for up to eight months — long enough for an amazing journey.

So Aurora flew. She rode the warm air rising from the ground in lazy spirals, then glided for miles without flapping. She followed the sun by day, using it like a compass.

In a meadow in Ohio, she stopped to drink from goldenrod flowers and met thousands of other monarchs. "Where are you going?" she asked one.

"The same place as you," said the other butterfly. "To the mountain forest. None of us have been there before. But we all know the way."

The journey wasn't easy. A thunderstorm in Missouri forced Aurora to cling to the underside of a leaf all night. In Texas, the wind blew so hard she had to rest for two days. She was careful to drink as much nectar as she could, storing up energy as fat inside her body.

Each night, the monarchs gathered by the hundreds on tree branches to rest, covering the leaves in orange and black like autumn decorations.

After nearly two months and more than two thousand miles, Aurora crossed into Mexico. The land rose into tall mountains. And there, high up among the cool fir trees, she found it.

Millions of monarchs covered the trees. They clustered so thickly that branches bent under their weight. The whole forest seemed to glow orange.

Aurora settled in among them. The cool mountain air helped the butterflies stay calm and save their energy all winter long.

When spring came, Aurora and the others woke up, fluttered down to drink, and began to fly north again. Along the way, Aurora laid her eggs on milkweed plants in Texas.

She would not make it all the way back to Canada herself. But her great-great-grandchildren would — and next autumn, one of them would feel the same quiet pull toward the south, and find their way to a forest they had never seen.
