Who is the animal meteorologist?

Animal meteorologists include dragonflies and spiders.

1, the dragonfly flies low, which means it's going to rain.

2, the spider forecast weather method-rainy days, such as air pressure rises, humidity decreases, insects fly high, spiders will open their nets to catch, indicating that the weather will clear up. On the contrary, the spider closes its net, which indicates that it will rain.

Extended data:

1794 In the early winter, the French army invaded the Netherlands. Unable to fight, the Dutch had to open the canal gate and try to flood the road with water to stop the French attack. Facing the huge flood, the French army is ready to go home. At this time, the commander of the French army, who knew a little about biology, found that the spider turned the net abnormally, but he urgently ordered the troops to stop acting and stand by.

Because he knows that spiders only do this in sunny and cold weather. Sure enough, the temperature suddenly dropped soon, the water soon froze, and the French army went straight into the ice cave. It was the spider's barometer that helped the French army a lot.
