Why do ants move before it rains?

Some people think that ants can predict air humidity. When they feel too wet, they know it's going to rain, so they must move to a safer place. However, there is still no conclusive scientific evidence to prove this view.

It is also said that ants choose cloudy days or night activities, mainly to prevent the possible damage to ant eggs caused by sun exposure. Because people don't pay attention to the actions of ants at night, they can often see the activities of ants on cloudy days, so they associate ant activities with rain.

Extended data:

First, ants build nests.

Ants are gregarious insects and have a strong love for their nests. Most species nest underground or in trees. They have a variety of feeding habits, usually plants and meat. Spiny ants, like other ants, generally take nests as their homes. There are one or dozens of queens in a nest. Worker ants specialize in nesting, foraging, feeding and other work, with the largest number.

In the wild, when savage harvesting ants build their nests, they will separate their usual habitats from the storeroom where seeds are stored. The storeroom is higher than the usual habitat. If the storeroom is placed in a dry environment, the seeds will not germinate easily.

Second, grazing.

Ants have an extraordinary ability to "eat" aphids to get food. Aphids, also called honey bugs, suck the juice of plants and secrete a sticky and transparent sweet liquid-honey dew, which is the "milk juice" that ants love very much.

Ants will protect these aphids from ladybugs or other predators, and from time to time stimulate the abdomen of aphids with tentacles, so that they can continuously secrete "honey dew"-just like herders raising cows. When aphids on a branch multiply too much, ants will bring them to new branches and leaves, just like herders looking for new pastures.

Ants sometimes leave aphid eggs in the nest. As soon as the young aphids hatch, the ants carefully send them to the twigs, just like people lead cows to the grass.

On the surface, both ants and aphids benefit from this relationship, but scientists have found that ants secrete a chemical to calm aphids, inhibit the growth of aphids' wings, and make them quiet and slow, more subject to the control of ants. In fact, the "cow of ants" aphids have become slaves of ants.
