    Lethal freezing occurs when insects are exposed to temperatures below of their body fluids;

    Thus an insect exposed to freezing temp . is most likely to die .

    Insect winter ecology entails the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds.

    This is because unlike those animals, which can generate their own heat internally (endothermic), insects must rely on external sources to provide their heat (ectothermic).

    Thus, insects sticking around in the winter, must tolerate freezing or rely on their surroundings to provide enough heat to avoid freezing.

    Loss of enzymatic function and eventual freezing due to low temperatures daily threatens the livelihood of these organisms during winter.

    Not surprisingly, insects have evolved a number of strategies to deal with the rigors of winter temperatures in places where they would otherwise not survive.

    Yes, in most cases it will die. Some of them don't freeze except at very low temperatures.

    "Most freeze-tolerant species restrict ice formation to extracellular spaces. Some species, however, can tolerate intracellular freezing as well. "

    "The alpine cockroach Celatoblatta quinquemaculata is common at altitudes of around 1500 m on the Rock and Pillar range of Central Otago, New Zealand where it experiences freezing conditions in the winter. The cockroach is freeze tolerant, but only to c. -9 degrees C."
