Fruit flies mate more frequently once RCH has commenced, compared to a control insect group not experiencing RCH. Most insects experiencing extended cold periods are observed to modify

If intracellular freezing occurs, it will lead to death. Freezing injury is a result of lost permeability, plasmolysis, and post-thaw cell bursting.

The lab injected the larvae with added glycerol and in turn proved that glycerol is a major factor in survival rate when cold hardening. The

Cold hardening of insects improves the survival rate of the species and improves function. Once environmental temperature begins to warm up above freezing, the cold hardening process is reversed and the glycerol and cryoprotective compounds decrease within the body. This also reverts the function of
