How do ants tell the way? How do ants tell the way?

In life, we can often see swarms of small ants crawling far away from the nest to forage for food, but they can always find their nest in and out. So what do ants rely on to discern their direction? I solved this mystery experimentally.

1. Methods: (1) Observe the situation of ants near their homes foraging and returning to their nests. (2) The antennae of ants were treated differently, and 8 ants with all antennae cut off (group A); 8 ants with 1 2 antennae cut off (group B); Cut off 1 3 antennae of 8 ants (group C).

2. Test: Put the 8 ants caught in the nest at 40cm, 20cm, and 10cm away from the nest to observe their return to the nest. Group A ants were placed 40 cm, 20 cm, and 10 cm away from the nest to observe the return to the nest.

Group B ants were placed 40 cm, 20 cm, and 10 cm away from the nest to observe the return to the nest. Finally, group C ants were placed 40 cm, 20 cm, and 10 cm away from the nest to observe the return to the nest. Experimental Results:

1. Ants that have not cut their antennae foraging can return to the nest smoothly, and even if they set up "roadblocks", they can still return to their "home" smoothly. 2. The return of each group of ants with tentacles cut: the ants whose antennae have all been cut off are dizzy, unable to distinguish the direction, and cannot return to the nest.

Ants with half of their antennae cut off, although the antennae are more complete than those of group A, are still useless. Cut off 1 3 antennae of ants at 40 cm, sniffing east and west, and seem to be looking for a way back. But after all, 1 3 tentacles were missing, and it was so far away, so it didn't make it back to the lair in the end.

At 20 cm they also fail to return to their nests, and sometimes they have found the right route but then go in circles and lose their way. Finally, at 10 cm, they were finally able to find their nest, but they still crawled and stopped, and it took a long time to reach their home. <>

Ants rely on their sense of smell to identify routes, and they rely on sunlight to identify directions, and their antennae are more agile than a blind man's bamboo pole. Because this pair of antennae has two functions: one is the tactile effect, through the contact with the outside world, you can detect the contour, shape and hardness of the object in front, as well as the terrain undulation of the road ahead.

This effect is exactly the same as that of a blind man's bamboo pole. The other is olfaction, which is identified by smell. This is something that the blind man's bamboo pole does not have.

It turns out that while walking, ants continue to secrete a small amount of chemicals with a special smell from the glands on the end of their abdomen and legs, called markers, which are contaminated on the road and leave traces. When the nest ants that are far away from the nest return to the nest, they use their special nose - antennae to smell this smell sign, which is called "scent navigation". Use your fingers to rub the ant vigorously several times on its way home to destroy its original chemical odor signpost, or put a sanitary ball and let the scent of the sanitary ball cover the smell of the marker substance.

At this time, you will see many ants crawling to this place, and then immediately stop moving forward and make a mess on the spot. Because they can't smell the original smell for a while, they are temporarily lost. If you continue to observe, you will find that after a short time, they touch each other with their antennae, as if they are talking to each other

The road sign ahead has been destroyed, and we have to find a way to do it quickly." They stop and go, going around in circles. Eventually, they will try to bypass the odor line and re-establish a new route back to the nest.

How did the ants rebuild the new road signs? In general, another means of positioning is used. That is, relying on the position of the sun and using polarized light in the sky to navigate, also known as astronomical road signs.

This secret was discovered a long time ago by the French entomologist Fabre. The eyes of ants are natural polarized navigators. Foraging ants can accurately return home by recognizing the direction of the sun and counting steps.

Rely on the antennae to identify the direction of the odor**.

Ants, like other insects, rely on their antennae to distinguish smells, and the first segment of the antennae is swollen and knee-shaped, making them very flexible. Because the antennae are a pair, they can not only distinguish the intensity of the smell, but also distinguish the direction and distance of the smell**, and the adults exchange food with each other, and learn about each other's health and nutritional status through their smells, and the food found by each other.

At the same time, it can also distinguish the group that the other party belongs to that kind of task, such as digging holes and building nests, or collecting food. In general, older worker ants are sent out of the nest to work.

The antennae are important sensory organs of insects, mainly playing the role of smell and touch, and some also have auditory functions, which can help insects to communicate, find the opposite sex, find food and choose spawning sites.

Insects are always swinging their antennae from side to side, as if two antennas or radars are always receiving radio waves and tracking targets. Because there are many sensory and olfactory organs on the antennae, which are connected to many sensory nerve endings in the antennal fossa, and directly connected to the central nervous system, they are very sensitive, and can not only feel objects, feel airflow, but also smell various odors, even from a distance.

Ants have the ability to discern directions. Ants rely on their antennae to identify odors and identify their ** direction. Ants rely on their antennae to distinguish smells, and the first segment of the antennae is swollen and knee-shaped, making it very flexible.

Since the antennae are a pair, it is possible to distinguish both the intensity of the odor and the directional distance of the odor**.

Ant is a kind of insect, also known as ant, Xuanju, kun mayfly, mayfly ant, belonging to the phylum Arthropod, Insecta, Hymenoptera, Ant family. There are many species of ants, there are more than 11,700 species known in the world, there are 21 subfamilies and 283 genera, and there are more than 600 species of ants that have been identified in China. Ants are also famous architects in the animal world.

They use their jaws to dig holes in the ground and build their nests by carrying sand one by one. The "chamber" of the anthill will remain in its original form unless the soil is severely dried out. Ant research expert Walter Chilgel models an anthill.

He poured liquid metal, paraffin, or orthodontic plaster into the colony of the invading red fire ants, solidified it, and then dug it out.

Ants mainly rely on the sense of smell to identify the route, relying on sunlight to identify the direction, the ant's antennae are very smart, because the ant's antennae have two functions: one is the tactile effect, through the antennae contact with the outside world, you can detect the outline, shape and hardness of the object in front, as well as the terrain fluctuations of the road ahead, and the other is the light sensing function, which can distinguish the direction according to the intensity of the sunlight.

Ants mainly rely on the sense of smell to identify the route, rely on the sunlight to identify the direction, the ant's antennae are more agile than the blind man's bamboo pole, because the ant's antennae have two functions: one is the sense of touch, through the antennae contact with the outside world, you can detect the outline, shape and hardness of the object in front, as well as the terrain ups and downs of the road ahead, and the other is the photosensitive function, which can distinguish the direction according to the intensity of sunlight.

Ants have two antennae, and they can rely on their antennae to identify directions.

How many ways do ants identify their direction? What are the types?

There are three ways for ants1 Suppose an ant uses its antennae to find its way: select an ant that is about to return to the nest, pick it up and remove its antennae with tweezers, and then put it back in place to see if it can still follow the team back to the nest. 2 Suppose the ant uses its surroundings to find its way:

While a group of ants are on their way back to the nest, use a simple screen to enclose them, and then use a flat plate to place it very low above the returning ants so that they cannot see the sky and the surrounding scenery. Under such conditions, if the ants can still return the same way, it means that the ants do not necessarily rely on the surrounding scenery to find their way. 3 Suppose the ants leave a scent on the path they have climbed on, and use the smell to identify the road when they return:

On the pavement where the ants crawled, use your finger to cross a line, disrupting the continuous scent. If the ants can still go back the way they came, it means that the ants are not using the smell left by themselves to find their way; Conversely, if the ants are confused for a short period of time, it means that the ants may be using smell to discern directions.

Hello, ant moving may be impermanent to help us discern direction, but it can help us tell that it may be raining soon.

Ants often move before the rain, and if they want to move before the rain, they move to higher places, because the lower places are easy to be flooded.

Ants have a very keen eyesight, not only the scenery on land will be used by ants to identify the way, but also the position of the sun and the sunlight shining from the blue sky can be used by ants to identify the direction of returning to the nest. In addition, in addition to relying on their eyes, ants can also recognize their way based on smells. Some ants leave a scent on the ground they crawl on, and as long as they follow it when they return, they will not go astray.

There are also ants who do not leave any special smell on the road they crawl on, but they can memorize the smell of natural gas on the road to and from and find a home.

An ant (ant) is an insect. It belongs to the phylum Arthropoda, Insecta, Hymenoptera, and Antidae. There are many species of ants, there are more than 11,700 species known in the world, there are 21 subfamilies and 283 genera, and there are more than 600 species of ants that have been identified in China.

New species of ants that reproduce asexually have also recently been discovered. Ants live for a long time, from a few weeks to 3-10 years, and a queen for more than a decade or decades, or even more than 100 years. An ant nest can grow from 1 to 10 years in one place.
