How is diapause different from hibernation?

Diapause is a physiological state that some insects and other organisms enter during unfavorable environmental conditions, allowing them to pause development and conserve energy until conditions improve. In contrast, hibernation is a behavioral adaptation primarily seen in mammals, where the animal enters a state of reduced metabolic activity and lowered body temperature to survive cold periods. While diapause is often triggered by external cues like temperature and photoperiod, hibernation is more about energy conservation in response to food scarcity and cold. Essentially, diapause is a developmental pause, while hibernation is a survival strategy.
