Why do ants move when it rains?

When it rains, ants will move because it can predict the humidity of the air. When it feels the humidity is too high, it knows it's going to rain, so it must be moved to a safer place.

Ants generally nest underground, and the scale of underground nests is very large. There are good drainage and ventilation measures. General worker ants are responsible for nesting. The entrance and exit are mostly a small arched mound with a hole in the middle like a volcano.

Secondly, there are ventilated holes, and each room in the nest has a clear classification. Warm and moist soil is their favorite. They usually live in arid areas, but it is little known that they can barely survive in water for two weeks.

Ants are "architectural experts"

Ants are definitely experts in architecture. There are many compartments in the ant nest, and these compartments have their own uses. The ant nest is solid, safe and comfortable, and the roads extend in all directions and are complicated. There is also a circle of soil outside the ant nest, and there are some places to store food. Ventilation is cool, warm in winter and cool in summer, and food is not easy to deteriorate.

Ants are also famous architects in the animal world. They dig holes in the ground with their jaws and carry sand grain by grain to build their nests. The "room" of the bird's nest will keep its original shape unless the soil is seriously dry.
