How do ants return to their nests when it rains?

This is the only known photo of an ant with a nose. This special adaptation conforms to the "scientific" concept that ants can smell pheromones. They can't, because these little demons have neither an olfactory system nor a brain to process information. In addition, they do not release pheromones. The key is "mating season"

When a "princess" takes off, she will be attracted by a "man". This "man" has been implanted with a specific charge from the sun-"he", and then transferred to the princess, and she will be crowned queen immediately (how can I say, old guy). Then it flew to the ground and began to breed. Every ant she makes has this specific charge, which is how they distinguish intruders from their companions.

The carbohydrates they bring into the mound are not food. These things will be processed by the queen ant into eggs of just the right size (she doesn't have her own egg-making system). This is an electrically balanced thing.

The signal sent by the fire ant pile can only be received by the ants on this mound. Whether it is sunny or rainy, they find their way home in this way. I haven't studied other kinds of ants deeply, but I can logically infer that they have similar systems. Thousands of "knowledge" are ridiculous and should not be regarded as "science" at all.

The best and worst worry is that Pharaoh ants triangulate Polaris-their anthills and nearby landmarks move at night. I laughed till I cried. * These little boogers fly very fast. Can you imagine trying to connect when you are moving at hundreds of feet per second?

If a good rain can wash away the traces of pheromones, it may be difficult to do so. However, ants have other navigation methods. They can navigate through the sun compass. Even if the sun is covered with clouds, there are plane polarized light in the sky that we can't perceive, but they can. Even if they can't see the sun, it can tell their little brains where the sun is. The brain can also calculate how many laps, degrees and steps ants have taken, and use this information to navigate back.

In addition, when it rains, changes in air pressure and smell will warn insects and other animals. Flying insects take refuge in places such as the back of leaves. Ants may act on this information and flee to their nests before it rains.
