Pyrrharctia isabella (banded woollybear)

Wikipedia Abstract

The Isabella Tiger Moth (Pyrrharctia isabella) can be found in many cold regions, including the Arctic. The Banded Woolly Bear larva emerges from the egg in the fall and overwinters in its caterpillar form, when it freezes solid. It survives being frozen by producing a cryoprotectant in its tissues. In the spring it thaws out and emerges to pupate.
