How do ants spend the winter?

How do ants spend the winter? Ants are omnivorous, mostly black, brown, yellow or red, and their bodies are smooth. When I was a child, I always looked at these little creatures on the ground, and we were all amazed to see ants lifting things bigger than themselves. The following is about how ants spend the winter.

How do ants spend the winter 1 After the autumnal equinox, the weather turns cold, the temperature begins to drop, and ants are in the preparation stage of hibernation. After beginning of winter, the temperature dropped, ants gradually stopped moving and foraging, went into hibernation and ate stored food for the winter.

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 dry areas. They can barely survive in water for two weeks.

Eating habits

Ants are divided into: lower species, carnivorous, feeding on insects, small animals and even dead animals; Stinky ant subspecies, Formicidae and higher species of Formicidae can feed on animals and plants, especially honeydew secreted by aphids and scale insects; Most other ants are omnivorous, feeding on seeds, fruits and insects.

For example, Polyrhachis bidentata has high omnivorous species, and can feed rice bran, wheat bran, beans, sugars, melons and fruits, and animal feed such as fish meal, silkworm chrysalis, bones, eggs, dead insects, etc. , can also be fed with chicken feed or homemade feed. Ants in Formicidae and Formicidae generally only eat meat.

How do ants spend the winter? 2 1, hoarding food for the winter

Before winter comes, ants will move all kinds of food back to their nests and hoard them for the winter. When the temperature drops to a certain extent, the ants stop coming in to look for food and simply stay in the nest to reduce the consumption of various functions of the body and reduce metabolism. When they are hungry, they will eat food hoarded.

In addition, ants may spend the winter in caves with animals such as wealth insects, scale insects and gray butterfly larvae. These animals can secrete honey dew, so that ants can eat some nutritious sweets in winter.

Step 3 seize territory

Ants can grow normally at 15-40℃, but the optimum temperature is between 25-30℃. But every spring, when the hoarded food is exhausted, the ants will come out of the hole at low temperature.

But the first thing ants do after leaving the nest is to divide the scope of power to prevent the invasion of other ant nests. As far as ants are concerned, land is the main food source. In order to divide the land for food, ants will even wage war.

Division of species

Ants develop into complete metamorphosis. All ants live in social groups. Generally speaking, there are four different kinds of ants in a group.

Queen Ants: Reproductive female ants, or female ants, are the largest in the colony, especially with large abdomen, developed reproductive organs, short antennae, small chest and feet, wings, wings or no wings. The main responsibility is to lay eggs, breed offspring and manage this big family.

Male ant: or father ant. Small head, undeveloped upper jaw and slender tentacles. It has developed reproductive organs and external genitalia, and its main function is to mate with the queen ant.

Worker ants: capable ants. Wingless, generally the smallest individual in the group, but the largest number. The compound eye is very small, and the monocle is very small or not. The maxilla, antennae and three pairs of pectoral feet are well developed and good at walking. Worker ants are infertile. Female. The main duties of worker ants are to build and expand nests, collect food and feed young ants and queens.

Soldier ant: It has a big head and a well-developed upper jaw. It can crush hard food and become a fighting weapon when defending groups.

How do ants spend the winter? 3 1. Before winter comes, ants will move all kinds of food back to their nests and hoard them for the winter. When the temperature drops to a certain extent, ants stop going out for food and stay in their nests with little activity, thus reducing the consumption of various body functions and metabolism. When they are hungry, they will eat food hoarded.

In addition, ants may spend the winter in caves with animals such as wealth insects, scale insects and gray butterfly larvae. These animals can secrete honey dew, so that ants can eat some nutritious sweets in winter.

But the first thing ants do after leaving the nest is to divide the sphere of influence and prevent ants from other nests from invading. For ants, land is the main food source. In order to carve up the land and find food, ants even wage war.

Ants usually spend the winter in caves. Before winter, they will bring all kinds of food back to the ant nest, and at the same time carry aphids, scale insects, horned cicadas and gray butterfly larvae in the ant nest to wait for the winter, and absorb excrement from these insects as food (milk honey). When winter comes, ants will not go out for food, because there is enough food in the nest, and they will start the winter mode.

morphological character

Ant family (3) The body of an ant is divided into three parts: head, chest and abdomen, with six legs, thin and elastic body wall, membrane wings, hard and fragile.

The head varies greatly, usually wide and big. Compared with body weight, head weight is the most important among terrestrial animals. The antennae of sexual and asexual females are knee-shaped, while those of males are simple, with 4- 13 nodes. Compound eyes are small, shrink back, and occasionally not at all. Three eyes, located on the top of the head, worker ants still have no eyes.

The mouthparts are developed, the upper lip is degenerated, and the maxilla has various shapes, such as wide and large, long and short, straight and curved, or single tooth. The mandible is normal, with 1~6 joints. The inner jaw is simple. The lower lip has beard, chin, middle lip and two small side lips; Lower lip 1~4.

Empty the box

The first abdominal segment (combined with the thoracoabdominal segment and the posterior chest) healed and elongated. The abdomen is located behind the thoracoabdominal segment, and the front end of the abdomen is obviously contracted into an abdominal stalk.

The abdominal stalk is one or two segments. If there are two segments, the second segment is called the posterior abdominal stalk. Each lymph node has one or two back tumors, or erect or inclined scales. The posterior segment of the stem expands to form the abdomen, which consists of 7-8 segments, and the male ant has one more segment than the female ant. There are 8 pairs of air holes in the abdomen. Some genera are vocal organs, which consist of files on the posterior abdominal stalk and friction surfaces on the first segment of the posterior stalk.

eating habits

Ants are divided into: lower species, carnivorous, feeding on insects, small animals and even dead animals; Stinky ant subspecies, Formicidae and higher species of Formicidae can feed on animals and plants, especially honeydew secreted by aphids and scale insects; Most other ants are herbivores, and they mostly feed on dead leaves, seeds, fruits and branches.

Polyrhachis vicina is a higher omnivorous species, which can feed rice bran, wheat bran, beans, sugars, melons and fruits, animal feed such as fish meal, silkworm chrysalis, bones, eggs, dead and live insects, etc. , or chicken feed or homemade feed.

Planting honey dew as food; I often eat human food indoors. Japanese ants can harm crops and agriculture. Beneficial species, such as ants, can prey on agricultural pests; Working people in China used it to control citrus leaf beetle 1600 years ago. In addition, Fujian used red ants to control sugarcane borers, and the effect was quite good.
