Summary:
The immature stages of two species of spiders, the crab spider, Philodromus sp. (Philodromidae), and a sac spider, Clubiona sp. (Clubionidae), overwinter under the bark of standing dead trees and survive subzero temperatures by depressing their supercooling points in winter. This document describes how a thermal-hysteresis protein acts as an antifreeze agent and lowers the supercooling point of insects. This protein appears to be similar to protein and glycoprotein antifreezes that were previously found in polar marine fishes and certain overwintering insects.
