What advantage does the Woolly Bear's adaptation grant it compared to species utilizing Freeze Avoidance?

Answer

It allows the species to inhabit northern latitudes where other lepidopteran species cannot persist year-round.

The development of robust Freeze Tolerance, achieved through the complex synthesis of cryoprotectants, grants *P. isabella* a significant selective advantage over insects that rely solely on Freeze Avoidance (supercooling). Because the Woolly Bear can actively manage and survive being frozen solid, its geographical range expands into colder, northern latitudes where species restricted to freeze avoidance—which face risks from internal ice nucleation—cannot typically survive the entire year. This physiological capability supports its long-term persistence in diverse, often severe, climates.
