Why can ants predict the weather?
Before it rains, due to the increase in humidity in the air, the amount of water absorbed by the soil increases. As a result, ant nests living in the soil become moist.
Although the ant lives below the ground, it likes dryness by nature. It has an organ on its body that senses moisture. Before a heavy rain, when the moisture in the air is too high, it feels that it is about to rain. When it rains, ants will crawl out and move to higher ground to avoid being flooded by rain.
Ants predict the weather by moving. Once it is going to rain, they move one by one. If they move lower, it means the rain will be lighter; if they move higher, it means the rain will be heavier.
When ants block the entrance to their nest, it indicates that there will be heavy rain. This is because ants are very sensitive to changes in air pressure and humidity. Once they feel that it is going to rain heavily, they will block the entrance of their nest to prevent rainwater from seeping in and ensure their life safety.
When they move, sometimes they move from east to west, sometimes from west to east. This tells us that where they move from, it will rain! However, if there is only a drizzle, it will be difficult for the ants to observe.
Extended information:
The response measures of ants are usually divided into two types:
1. Build embankments. Worker ants go out in groups and use soil to seal the ant nests. The hole is blocked to prevent rainwater from entering. This is a typical behavior to prevent rain, because ant nests are usually very deep and have enough ability to withstand rain. Sealing the hole can protect the internal structure from damage to the maximum extent.
2. Move, move from one ant nest to another. This is also a measure for ants to cope with rainy weather, but it does not necessarily mean rain. It is also possible that the previous ant nest was too humid for survival due to other reasons, or the original ant nest was not big enough, which caused the ant attack. The act of moving.
