Scientific name: Pyrrharctia isabella 
 

Biology & Ecology: The Banded Wolly Bear, or Pyrrharctia isabella, is a moth. This moth has two life stages, a larva and a moth which is named the Isabella tiger moth. This species starts off as an egg, then emerges during the fall/  beginning of winter as a caterpillar. Then it freezes solid!! Its heart stops beating, and then its gut, and its blood. It can survive by using a cryoprotectant. This a subtance that the animal uses to protect biological tissue from freezing. Then it thaws out in the spring time to pupate. Once the moth comes from its pupa as a moth, it dies in a few days. In the artic, where the summer food is shortened, the caterpillar feeds for many summers, freezing itself every winter.  Some can live up to 14 winters.
