JUL 5, insects: cryoprotection

Authors' Note: The isabella tiger moth, Pyrrharctia isabella enters the cold season in wintry parts of North America in the form of a banded woolly bear caterpillar. Traditionally, her peer-group would attempt to get through the winter by altering their metabolism to manufacture compounds known as cryoprotectives, allowing them to recover from freezing. Our protagonist seems to have discovered another way around this challenge.
