Why do scorpions often hide under rocks and bark during the day?

Scorpions are adapted to conserve water and avoid overheating, which is why many species stay hidden during the day. Rocks, bark, logs and burrows provide shade and stable humidity, reducing the risk of desiccation. At night they emerge to hunt insects and other small animals using sensory hairs and vibration detection. This behavior is especially important in deserts, where temperature swings can be extreme. Their secretive habits are one reason scorpions have persisted successfully for hundreds of millions of years.
