Animals work similarly. I had the chance to talk recently to Dr. Marlene Zuk — an evolutionary biologist — for a different piece on cicadas and she told me that insects and other animals are also sensitive to temperature and light changes and so either prepare to hibernate or try to mate before their life cycle is over. Hibernation for insects can take the shape of cocooning, or developing underground (like yearly cicadas) or even — in the case of some grasshoppers — seeking refuge and shutting down everything but basic life functions, in a self-contained suspended animation of sorts, so they can emerge in the spring ready to go.
So check out nature this fall! It's not dying, just preparing for winter!
