For the stressful period without food (often lasting many months) adults prepare in time by accumulating reserves (lipids, glycogen, proteins) and substances needed for resistance to future hazardous changes of environmental conditions. Growth and development are reduced, and insects have increased resistance to extreme conditions and reduced activity or altered behavior.

For example, the woolly bear caterpillar must endure a period of chilling to trigger the end of diapause and continuation of the life cycle. It enables insects and related arthropods to circumvent For example, some insects like the firebug accumulate certain chemicals which help in lowering the freezing point. Some insects require specific thermal cues to end the diapause phase. Diapause is a form of developmental arrest in insects that is much like hibernation in higher animals. It enters into diapause due to some adverse environmental conditions such as drought, extreme temperature, reduced food availability; which, in turn, delays the overall development.
