Why do some insects enter diapause instead of staying active all year?
Quick Answer
Diapause is a controlled dormant state that helps insects survive cold, drought, or food scarcity. It is a survival strategy, not just sleep.
The Full Story
Many insects enter diapause when conditions become unfavorable, such as winter or dry seasons. Unlike simple inactivity, diapause involves major physiological changes that slow development and conserve energy. Hormonal signals prepare the insect in advance for an adverse season. This lets species synchronize life cycles with changing environments and improve survival rates. Diapause is common in butterflies, beetles, mosquitoes, and many other insect groups.
