Some caterpillars have evolved with antifreeze in their body cavities, allowing them to become cater-Popsicles to survive cold winters. But climate change could threaten that.
So there are caterpillars that have been reported to be put into an ice cube and frozen, and then when the ice cube melts, they can get up and walk away. You may have seen them scooting around on leaf litter in the fall. These little creatures have an orange waistband stripe, whose width is rumored to predict how long winter might be. And while this is based in colonial folklore, not science, what is scientifically amazing is how the woolly bear caterpillar is able to survive winter.
