How many species of ants are there in the world? Which ones are more scary

There are about 16,000 species of ants, and they are extremely widely distributed. Modern ant experts anti-ants are divided into 9 subfamilies:

1) Subfamily Sphecomtrmiae

2) Pseudomtrmeinae

3) Subfamily Dolichoderinae

4) Ant subfamily (formicinae).

5) Ponerinae

6) Subfamily cerapachtinae

7) The subfamily Dertlinae

8) Leptanillinae

9) Subfamily Myrmicinae

All over the world, with the exception of Antarctica, the Arctic, and snow-capped peaks, ants are found on almost all land.

Ants have a long history and a long history. Judging by the amber fossils embedded in ant remains found on the Baltic coast, the ants are at least 45 million years old, and in fact their ancestors date back to the Mesozoic Era more than 100 million years ago. With the changes of the environment and history, the huge dinosaurs have long been extinct, and the small ants rely on the collective strength to survive and reproduce.

Today, it is a thriving kingdom with the largest number of millions of terrestrial animals. The body of the ant is divided into three parts: head, thorax, and abdomen, with six legs, thin and elastic body walls, membranous wings, hard and brittle. The head changes a lot and is usually broad.

Head weight is the most important in terrestrial animals compared to body weight. The antennae of sexual and asexual females are knee-shaped, and the antennae of males are simple, 4-13 segments. The compound eye is small, withdrawn, and occasionally completely absent.

3 in one eye, located on the top of the head, worker ants or no single eye. The mouthparts are well developed, the upper lip is vestigial, the upper jaw has various shapes, wide and large, long or short, straight or curved, or has simple teeth, and the lower jaw is normal, with 1 6 segments. The inner jaw lobes are simple.

The lower lip has whiskers, subchin with a mesolabial tongue and two small lateral labial tongues; Lower lip tongue 1 4 segments. The chest is clear. The first abdominal segment (and the thoracoabdominal segment is elongated as the posterior thoracic phase heals.

The abdomen is located behind the thorax and abdomen, and the anterior end of the abdomen is markedly constricted to become the ventral stalk. The ventral stalk is one or two segments, and if there are two segments, the second segment is called the posterior ventral stalk. There are one or two dorsal nodules on each segment, or erect or oblique scales.

The posterior segment of the stalk is enlarged to form the abdomen, which consists of 7 or 8 segments, with males having one more segment than females. There are 8 pairs of stomata in the abdomen. Several genera have friction articulators, consisting of a file on the posterior ventral peduncle and a friction surface on the first segment of the posterior segment of the stalk.

There are currently 21 subfamilies and 283 genera of ants (after bolton 2003) The classification system of 16 subfamilies is mainly used, and compared with the system of 21 subfamilies, the new system divides several subfamilies from the subfamily of fierce ants). Ants are a common type of insect that is easy to identify. Generally, the color of the body is black, brown, yellow, red, etc., and the body wall is elastic, smooth or hairy.

The mouthparts are chewy, and the palate is well developed. Antennae knee-shaped, 4 13 segments, peduncle segments very long, terminal 2 3 segments distended. The first segment or segments of the abdomen are knotted.

Winged or wingless. The distance of the forefoot is large, comb-shaped, and it is a horn cleaner (used to clean the antennae). It is a polymorphic social insect.

It is estimated that only about half of the ants – currently about 11,700 species – have been described. A larger study of ant fauna is also pending.

Ants are the most common and most abundant insect species on Earth. Since all kinds of ants are social groups, they were commonly called "ants" in ancient times. According to the modern scientific classification of morphology, ants can be divided into two major populations: ants and termites.

Ants can live anywhere they can live, and they are the strongest creatures in the world to fight natural disasters.

Ants have a very long lifespan, with worker ants living for a few weeks to 3-7 years, and queens for more than a decade or decades. An ant nest can grow in one place for many years, or even more than 50 years.

The external form of an ant is divided into three parts: head, thorax, and abdomen, and has six legs. The ant eggs are about millimeters long, irregular oval, milky white, and the worker ants are small, about millimeters long, and the whole body is brown and yellow. Both male and female ants are relatively large.

The abdomen is fat, the head and chest are brownish-yellow, the anterior half of the abdomen is brownish-yellow, and the hinderior half of the abdomen is brownish. The male is about a millimeter long. The female is about millimeters long.

Ants are typical social insects, which have three major elements of social insects, namely, individuals of the same species can cooperate with each other to take care of larvae; a clear division of labor; And the offspring can take care of the previous generation for a period of time.

In addition, it should be pointed out that "termites" are not ants, and termites are very different from ants in terms of physiological structure, in addition to having the same society.

Biological behavior refers to the adaptive activities carried out by living organisms that are perceived externally. Ethology is the discipline that studies these activities. Morphology and behavior were first noticed, but it was not until the 19th century that people gained the theoretical and experimental means to study biological behavior.

The doctrine of evolution raises animal behavior to an adaptive level.

The current categorization of biological behavior is very confusing. From the perspective of genetics and development, it is generally divided into innate behavior and acquired behavior, that is, instinctive behavior and learned behavior. However, this classification method is not commonly used, and people generally divide behaviors according to their functions, but unfortunately this classification method is not strict, and there are a lot of overlapping areas.

There are about 11,700 species of ants known in the world, with 21 subfamilies and 283 genera. Ant is a kind of insect, also known as ant, Xuanju, kun mayfly, mayfly ant, belonging to the class of arthropods and insects, the ant family of Hymenoptera. The external form of an ant is divided into three parts: head, thorax, and abdomen, and has six legs.

The ant eggs are about millimeters long, irregularly milky-white oval, and the larvae are worm-like and translucent.

Social characteristics of ants:

Ants are a typical social group. There are three social elements: individuals of the same species can cooperate with each other to care for the young; have a clear division of labour; At least two generations overlap within the colony (not excluding individual cases) and the offspring are able to take care of the previous generation for a period of time.

Ants are definitely experts in building, and there are many chambers inside the nest, each of which has its own usefulness. The nest is firm, safe and comfortable, and the roads are well-connected and intricate. There is also a circle of soil outside the nest, and there are some places to store food, which is ventilated, cool, warm in winter and cool in summer, and the food is not easy to spoil.

There are 15,700 species of ants in the world.

At present, there are about 600 species of ants on the earth, and there are about 15,700 species of subspecies, such as honey ant subfamily, pseudoleafcutter ant subfamily, stink ant subfamily, etc. Ants are beneficial insects and pests, such as small black ants, which can digest some food waste and debris, which helps to improve the environment. And the most hated white ants in our house are pests, which not only destroy furniture, but also damage the rhizomes of plants.

Ants weigh between 25 and 60 mg, and queens can weigh more than 120 mg. If we take the average weight of 50 milligrams, the weight of 200 million ants in the world is 2 billion tons, which is much more than the total weight of humans in the world. Ants can lift objects up to 400 times their own weight, can carry objects that exceed 1,700 times their own weight, according to entomologists have shown that 10 ants can work together to carry objects up to 5,000 times their weight, which is a well-deserved "Hercules".

Habits2. Lifespan: The life span of ants is very long, workers can live for a few weeks to 3-10 years, and queens can live for more than ten or decades, or even more than 100 years. An ant nest can grow from 1 to 10 years in one place.

3. Eating habits: ants are omnivorous insects, eating meat and vegetables, and they also eat the corpses of dead insects, and they like sweets the most.

4. Shelter: Ants generally build nests underground, the scale of underground nests is very large, with good drainage and ventilation measures, and they prefer warm and moist soil, which can barely survive in water for two weeks.

1. Little Yellow Ants: The size of small yellow ants is very small, if you don't look carefully, it is difficult to find the existence of small yellow ants, but in fact, they are often found in the family kitchen or balcony and other places. Little yellow ants will bite human **, especially children's skin, so if there are small yellow ants in the house, they should be eliminated as soon as possible.

2. Big-headed ants: The head of the big-headed ant is larger than the body, so it is named the big-headed ant, and the big-headed ant will also infest the building, so if the big-headed ant is found near the building, they should be eliminated as soon as possible.

3. Worker ants: The body of worker ants is brownish-yellow, which looks dull and dull, and worker ants like to build nests on the side of the road or in the corner of the wall, and they are also easy to see in the kitchen and other places.

4. Black ants: Black ants are mainly distributed in Taiwan, the whole body is black or black-brown, black ants generally survive in tree holes and other places, and black ants are easy to find food.

Ant (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. [1]

New species of ants that reproduce asexually have also recently been discovered. Ants have a long lifespan, ranging from a few weeks to 3-10 years for worker ants and several years or even 10 years for queens. An ant nest can grow for several years or even more than ten years in one place. It is important to note that termites do not belong to ants.

There are 21 subfamilies and 283 genera of ants, and the main classification system of 16 subfamilies is used, and compared with the system of 21 subfamilies, the new system divides several subfamilies from the mammoth ant (ponerine). Generally, the body is small, the color is black, brown, yellow, red, etc., and the body wall is elastic, smooth or slightly hairy. The mouthparts are chewy, and the palate is well developed.

The antennae are knee-shaped, the stalk nodes are very long, the terminal 2 3 nodes are distended, and the whole antennae are divided into 4 13 segments. The abdomen is knotted. Divided into winged or wingless.

The distance of the forefoot is large, comb-shaped, and it is a horn cleaner (used to clean the antennae).
