It will rain when spiders weave webs.

Everyone must have heard the proverb: "The ant moves the snake aisle, and it will rain heavily tomorrow." So in the impression of most people, ants and snakes are both animal "meteorologists" sent by nature. However, I came across another small animal, which can also predict the weather changes. This is the "Weaver Girl Master"-Spider.

One evening, I was walking in the street, and the street lamps on both sides of the road had started to work, flashing gray light. Even so, it attracts flying insects. Suddenly, I found a Zhang greatly's net under the lampshade of one of the street lamps. Occasionally a breeze blows, and the net will shake slightly, but it will not affect its firmness at all. Poor little flying bug. When they compete for their own dance, they completely ignore the danger around them. Several of them hit the ground and posted them on Zhang greatly's website. At this time, the webmaster appeared. It turned out to be a Okumo. Judging from his triumphant appearance, he can have a hearty meal tonight. However, there are gains and losses. Due to the arrival of many small flying insects, this originally strong and beautiful spider web was destroyed. What a pity!

In the next few days, when I was walking, I passed this street lamp. Stop every time to see if this spider has any harvest and whether its dinner is rich. No pains, no gains. For several days, this spider used her new net to catch delicious food.

Until one day, a strange phenomenon happened. While waiting quietly under the street lamp, I want to see the whole dining process of this "little fat man". However, I opened my eyes wide and didn't see the familiar net. The net is gone! But the spider is hiding in the corner of the lampshade, lazy and motionless! What happened? Master Weaver went on strike? Just as I was wondering, it began to rain in Mao Mao. No wonder this little guy didn't do it! It turned out that it had predicted that it would rain at the party, so it closed the net.

For several days, when I came to visit this spider with an umbrella, I didn't see it and its web. Finally, God put away his gloomy face and the rain stopped. I saw my old friend, the lovely spider, and it began to get busy again, weaving webs.

I'm curious: why do spiders have this ability to predict the weather? So, I consulted the relevant information and got the answer:

Scientists have found that spiders can predict the weather mainly because they are very sensitive to the humidity in the air. Spiders have many small spinnerets on their tails. On rainy days, due to the high humidity, water vapor is easy to condense into small water droplets in the spider's spinning part, so the spider feels difficult when spinning, so it stops spinning and closes the net. On the contrary, when the humidity in the air becomes smaller, spiders can spin silk smoothly, and they can net insects.

Spiders weave webs, and it will clear up after a long rain. This is the inspiration from spiders. In the future, we can also use spiders to weave webs to predict the weather.
