Can spiders predict the weather?

In many parts of our country. If you see a spider weaving a web, it will clear up in the rain. If the spider closes the net, it will become rainy.

Spiders can predict the weather mainly because they are very sensitive to the humidity changes in the air. There are many small spinnerets on the spider's tail, which are sticky and cold. When rainy weather comes, due to the high air humidity, water vapor is easy to condense into small water droplets in the spinneret, and spiders feel difficult when spinning, so they stop paying off silk and take up the net. On the contrary, when the humidity in the air decreases and the weather improves, spiders spin silk smoothly and then set nets to catch insects.

According to another study, spiders' legs can sense sounds with a frequency of 20 to 50 Hz. When the weather clears up, insects are easy to move, and the "buzzing" sound made during flight will soon be discovered by spiders and spiders, so they add screens to prepare for capture. This is why people observe the weather with the proverb "spiders hang on the net for a long time, but after the rain, it clears up".
