Why do spiders weave webs on rainy days?

Spiders will not weave webs on rainy days

The moisture on rainy days will invalidate the stickiness of spider webs, so weaving webs on rainy days is often in vain. Spiders only weave webs on sunny days. That is to say, the net is weaved when the air humidity is relatively low. On cloudy and rainy days, if the air pressure rises, the humidity decreases, and insects fly high, spiders will set up webs to catch them, which indicates that the weather will clear up. On the contrary, if the spider closes its web, it indicates that it will rain. As the saying goes: "Spiders spin webs, and if it rains for a long time, it will eventually clear up."
