What will spiders do before it rains?

Before it rains, spiders will hide in the corner caves in advance. Insects are very sensitive to the weather, and they will feel it when the temperature changes slightly.

Some spiders will hide under leaves or in cracks in walls to avoid the rain, and some spiders with nests will return to their nests to avoid the rain. And some spiders will find shelter from the rain at will. Spiders can be seen in many places in daily life. They are either weaving webs or wandering around, but we seldom find them moving outside when it rains.

This is because insects such as spiders are very sensitive to temperature and weather, and they can find a good place to shelter from the rain as soon as possible.

Extended data

Because spiders are highly sensitive to the changes of environmental factors including habitat structure, habitat type, wind, humidity and temperature, they can be used as indicator groups to monitor the changes of habitats and biodiversity, and their species composition and quantitative changes become important indicators of environmental monitoring, which can well reflect the process of environmental change and its impact on biodiversity.

Spiders mostly feed on insects, other spiders and multi-legged animals, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive close to catching prey within 30 cm and pounce on it.
