As climate changes, some butterflies take to the forests to shade themselves from the heat, new research suggests. However, not a large enough number of butterflies are making the move to save their populations, the researchers also found.
"A lot of the butterflies we were looking at are threatened by climate change. With the warmer temperatures, it will be too hot for a lot of them to survive in southern Europe," study researcher Andrew Suggitt, a graduate student at the University of York in the United Kingdom, told LiveScience.
The researchers were looking to see if the butterflies would move toward warmer or cooler areas of their habitats — like say a wooded, shaded area instead of an open, sunny field — depending on the temperatures.
