Butterflies in danger

Scientists from the University of Cambridge measured the temperature of 4,000 wild butterflies and warned that the existence of some species is threatened by climate change. The research was published in the Journal of Animal Ecology.

Butterflies are cold-blooded, so their body temperature depends on the surrounding environmental conditions. Researchers have determined that climate change and rising average temperatures pose a deadly threat to some species of butterflies. In the worst situation are colored butterflies, such as Peacock and Red Admiral, which have big problems with adapting to higher temperatures. Scientists also say that climate change is exacerbating this problem as we encounter extreme heat waves and surprising weather events more and more often.
