This year’s monarch butterfly migration is the smallest ever recorded. We’ll ask why. It’s a big story. Plus: how climate change is creating new hybridized species.
We love butterflies, and monarch butterflies are called “monarch” for a reason. They are grand. All that fluttering orange and black display on a winged scale built to impress. To charm. But monarch butterflies are in trouble. This year saw the smallest migration ever recorded to their winter retreat in the mountains of Mexico. And if you are looking this summer for monarchs, they’ve been hard to find. There’s a reason, and it goes back to genetically-modified crops, say my guests today. This hour On Point: monarch butterflies, beautiful and in trouble.
