Complete Facts and Trivia about Butterflies 04/10


Butterflies need an ideal body temperature of about 85ºF to fly. Since they're cold-blooded animals, they can't regulate their own body temperatures. The surrounding air temperature has a big impact on their ability to function. If the air temperature falls below 55ºF, butterflies are rendered immobile, unable to flee from predators or feed. When air temperatures range between 82º-100ºF, butterflies can fly with ease. Cooler days require a butterfly to warm up its flight muscles, either be shivering or basking in the sun. And even sun-loving butterflies can get overheated when temperatures soar above 100ºF, and may seek shade to cool down.
