Some butterfly species migrate in order to avoid the cold.
Although cold weather might shorten a butterfly's already brief life by rendering it immobile, others see the reduction in temperature as a signal to move. Butterflies are cold-blooded and require a body temperature of about 85 degrees Fahrenheit to activate their flying muscles. When the weather begins to change, some species will simply migrate in search of sunlight. Some, such as the North American Monarch, travel 2,500 kilometers on average!
