Since the cold-blooded butterfly can't regulate its body temperature, the insect
is particularly sensitive to changes in weather. Rain and wind can damage its
wings, and cold temperatures can render it literally unable to move its wings.
Butterflies have various methods for maintaining an ideal body temperature of
around 85 degrees Fahrenheit: they cluster together, hibernate in trees and other
structures, "shiver" by flapping their wings, and bask in the sun.
