Provide shady spots to protect butterflies from climate change — ScienceDaily

Researchers have discovered significant variations in the ability of different UK butterfly species to maintain a suitable body temperature. Species that rely most on finding a suitably shady location to keep cool are at the greatest risk of population decline. The results predict how climate change might impact butterfly communities, and will inform conservation strategies to protect them.

The results, published today in the Journal of Animal Ecology, show that larger and paler butterflies including the Large White (Pieris brassicae) and Brimstone (Gonepteryx rhamni) are best able to buffer themselves against environmental temperature swings. They angle their large, reflective wings in relation to the sun, and use them to direct the sun’s heat either away from, or onto their bodies. These species have either stable or growing populations.

More colourful larger species such as the Peacock (Aglais io) and Red Admiral (Vanessa
