The isаbellа tiger mоth cаn be fоund in many cоld regions, including the Arctic. The banded wooly bear larva emerges from the egg in the fall and overwinters in its caterpillar form, when it literally freezes solid.

How would you expect cells not being served by the circulatory system to produce ATP when the heart stops beating? What by-product would you expect to build up in the cells?
