In what weather do spiders weave webs?

Spiders can predict the weather mainly because they are very sensitive to 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 humidity in the air, water vapor is easy to condense into small drops at the spider's spinning hole, so the spider feels difficult when spinning, so it stops spinning and closes 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 20-50 Hz. When the weather turns fine, insects are easy to move, and spiders will soon find buzzing when they fly around, so they add wire mesh to prepare for catching. This is why people observe the weather with the proverb "a spider hangs a net, and it clears after the rain".
