What animal do bees belong to?

The generic term for HYMENOPTERA, Insecta. Italian bees and oriental bees are the main species, which are valuable for honey production and widely raised. Bees, whose chest backboard is less than the wing base, have branched or feathered bodies, and their hind feet are usually used for collecting pollen. Adults are covered with villi, and there are pollen collecting organs composed of long hairs on their feet or abdomen. Chewing and sucking mouthparts are unique characteristics of insects. Totally perverted. About 15000 species are known all over the world, and about 1000 species are known in China. Many kinds of products or behaviors are closely related to medicine (such as honey and royal jelly), agriculture (such as crop pollination) and industry (such as beeswax and propolis). They are called resource insects. bee

Bees belong to Hymenoptera and Apiidae. Body length is 8-20 mm, tan or dark brown, with thick hair. The head is almost as wide as the chest. The antenna is knee-shaped, the compound eye is oval and hairy, the mouthparts are chewing and sucking, and the hind feet are powder-carrying feet. Two pairs of membrane wings; The front wing is big, the rear wing is small, and the front and rear wings are connected by wing hooks. The abdomen is nearly oval, with less body hair than the chest and claws at the end of the abdomen. Bees are completely metamorphosed and go through four stages: egg, larva, pupa and adult.

In the bee society, they still live a matriarchal clan life. Among the members of their big family, there is a queen bee (queen bee), a female bee with reproductive ability, responsible for laying eggs and reproducing, and at the same time "ruling" this big family. Although the queen bee has mated, her eggs are not all fertilized. It can give birth to fertilized eggs and develop into female bees (sterile worker bees) according to the needs of large families; You can also have a fertilized egg and develop it into a drone later. When the extended family members of this group multiply too much, resulting in crowding, they should be grouped. The process of grouping is as follows: worker bees make a special hive-Wangtai, where queen bees give birth to fertilized eggs; After the larvae hatch, worker bees give them special treatment and feed them with highly nutritious royal jelly made in their bodies. After the larva develops into an adult, it becomes a new queen bee with reproductive ability. The new queen bee leads some worker bees to fly to form a new bee colony. Oriental bee. Both China bees and Italian bees are beneficial insects, and they are widely raised. In the process of reproduction, the new queen bee will be artificially grouped after birth, otherwise a queen bee will lead a group of worker bees to leave the hive and fly away, thus losing the colony. Beekeepers artificially produce royal jelly. In fact, they artificially made some queen bee platforms and put them in beehives for the queen bee to lay eggs. When the larvae hatch, the worker bees feed them royal jelly, and the beekeeper will take it out. In fact, beekeepers use deception, which shows that even smart bees are sometimes deceived.

There are many drones, and a group may be nearly a thousand. The only duty of the drone is to mate with the queen bee. When mating, the queen bee flies out of the nest, and the whole group of drones chases after it. It's called marital escape. The queen bee's marriage and mate selection are carried out through flight competitions, and only the winner can become a spouse. After mating, the drone's genitals fall off in the queen's genitals. At this time, the drone has completed its lifelong mission and died. When the males who failed to mate with the queen bee returned to the nest, they only ate and drank, and could not collect honey, becoming redundant idlers in the colony. After a long time, Feng Gong will deport them. Beekeepers don't want to keep too many drones in the bee colony and consume honey, so they are artificially eliminated. From this perspective,

Worker bees are the largest in this group. The number of worker bees kept by beekeepers in a colony varies with seasons, generally 2 1500 worker bees. Worker bees are the most industrious. The song "Little bees are busy all day, picking flowers and making honey" only refers to worker bees. In addition to collecting powder to make honey, building nests, feeding larvae, cleaning the environment and defending bees. It is also the task of worker bees. From spring to late autumn, bees are busy every day during flowering. Winter is the only short leisure time for bees. However, the cold weather and the low temperature in the hive are not good for bees, because bees are warm animals, and their body temperature changes with the temperature of the surrounding environment. The clever little bee came up with a special way to resist the cold. When the temperature in the hive is as low as 65438 03℃, they are close to each other in the hive and form spherical clusters. The lower the temperature, the closer the colony is, which reduces the surface area and increases the density of bee colony to prevent excessive cooling. According to the measurement, in the coldest time, the temperature in the bee ball can still be maintained at around 24℃. At the same time, they also use more honey and exercise to generate heat to raise the temperature in the nest. In cold weather, the surface temperature of the bee ball is lower than the center of the ball. At this time, the bees on the surface of the good ball drill into the center of the ball, while the bees in the center of the ball move outward. They took care of each other, changed places repeatedly and spent the cold winter. How do they eat honey stored in beehives during wintering and balling? Smart bees have their own tricks. They don't need to break up the spheres and climb out to eat separately, but pass them on to each other to get food. This can keep the temperature in the ball constant or change little, which is conducive to safe wintering. English name of bee: Bee Bee

The generic term for HYMENOPTERA, Insecta. Italian bees and oriental bees are the main species, which are valuable for honey production and widely raised. Bees, whose chest backboard is less than the wing base, have branched or feathered bodies, and their hind feet are usually used for collecting pollen.

Many kinds of products or behaviors are closely related to medicine (such as honey and royal jelly), agriculture (such as crop pollination) and industry (such as beeswax and propolis). They are called resource insects.

Bees lay eggs in nests, and larvae live in nests. The larvae living in groups are fed by worker bees, while the larvae living alone feed on the female bees in bee bread stored in the nest room. When the bee bread eats them up, the larvae mature and pupate, and emerge from the cocoon when they emerge. There are several generations in a year for domestic bees and 1 ~ 3 generations for wild bees. Overwintering with mature larvae, pupae or adults. Generally, males appear earlier than females, with short life span, and do not undertake the tasks of nesting, storing bee bread and raising offspring. Female bees build nests, collect pollen and nectar, and store them in the nest room. Their life span is longer than that of male bees.

Bees feed on plant pollen and nectar. Food habits can be divided into three categories: ① polyphagia, that is, eating different families of plants or flowers of a certain color (not limited to plant species), pollen and nectar of wishful bees and Chinese bees. (2) Oligophagia, that is, feeding on flowers of related families and genera, such as alfalfa wasps. (3) Monophagy, that is, feeding only from certain plants or related species, such as cornflower bees. The flowers interviewed by various bees are closely related to the length of mouthparts: for example, species with short mouthparts such as Labiatae, Aphidae and Aphidae interview the open flowers of Rosaceae, Cruciferae, Umbelliferae and Ranunculaceae; However, due to the long mouthparts, sawflies, honeybees and other species use deep flower tubes to interview flowers, such as Leguminosae and Labiatae.

There are three ways of life:

Sociality. Male and female worker ants live in the same nest, but there are differences in morphology, physiology and division of labor. Female individuals are large and good at spawning and reproduction; Males are smaller than females, specialize in mating and die after mating; Worker bees are small female bees with genital hypoplasia. They specialize in nesting, collecting food, feeding larvae, cleaning the nest room and adjusting the humidity of the nest. Italian bees and China bees are social species. Besides, there are bumblebees, tropical stingless bees and wheat bees.

Loneliness. The vast majority of bees live alone, that is, female bees nest alone to collect powder and store grain, and they have no "hierarchical" differentiation. Each nest room is open, the inner wall is coated with wax and other moisture-proof substances, and enough bee bread is stored in the room. Female bees lay eggs on the bee bread and close their nests. Larvae feed on bee bread in the nest. Most species belonging to this category are wild species, such as Aphidae, Aphidae, Formicidae, Tenebrionidae, Aphidae and Formicidae.

Parasitic. Female bees don't build nests, but lay eggs in the host's nest. Larvae generally has a large head and upper jaw, which is used to destroy the eggs or larvae of the host.

The nesting instinct of bees is complex, and the nesting place, time and nest structure are diverse. The nesting time is usually in the flowering period of plants. According to the nesting site and nest texture, it can be divided into the following categories: ① Species engaged in social life take wax secreted by themselves as spleen, such as bees, stingless bees, wheat bees and so on. The nest room is hexagonal. ② There are the most kinds of nests in the soil, and the interior of the nest room is coated with a mixture of wax and saliva to keep the humidity of the nest room. (3) The ways of using plant tissues to build nests are more diverse. For example, LEPIDOPTERA can roll plant leaves into tubes to form nests and put them in natural cavities; Mylabris uses plant hair to make wart nests on the stems; Lupine and LEPIDOPTERA insects nest on the stems of dead plants; Some kinds of bumblebees nest under the litter of the forest; Wood wasps drill holes in wood to build nests, and so on. (4) Others, for example, the genus Myzus uses saliva to adhere to small sandstone to build nests, and the genus Myzus builds nests in the shell of slugs.

Beehives are generally scattered, but there are also similar bees that have been concentrated in one place for many years, thus forming a nest group. For example, the number of nests of hairy feet can reach dozens or even hundreds.

The geographical distribution of bees depends on the distribution of nectar plants. It is distributed all over the world and has many tropical and subtropical species. The distribution of different subfamilies or genera has certain limitations For example, bumblebees in the bee family are mainly distributed in the north temperate zone and can extend to the Arctic, but there is no record of distribution in the tropics. Short-tongued bees are distributed in Australia; Trichogramma subgenus of Trichogramma of Meliaceae is only distributed in central Asia. Aphidae are distributed in tropical areas. Bees are distributed in different landscapes, and most of them live in desert grasslands, grasslands, forest grasslands, river valleys and mountains. Each landscape belt has a representative genus or species. For example, the ground bumblebee is a forest grassland species, the ground bumblebee is a typical grassland genus, and the quasi-bees are mostly grassland species.

According to fossil data, a large number of bees have been found in the late Eocene strata of Tertiary. Its appearance is closely related to the prosperity of flowering plants in the late Cretaceous.

Apiioidea is close to melioidea in classification, and its ancestor may have originated from a branch of melioidea. However, due to different eating habits, morphological characteristics tend to differentiate. The evolutionary characteristics of bees are: chewing and sucking mouthparts to form powder collectors and branching hairs; Eat nectar and pollen in adult and juvenile stages; The emergence of groups and social lifestyles; Polymorphism and parasitism in superfamily.

In Insecta, bees belong to the advanced evolutionary group. The emergence of social life style, the transmission of "language" information, the method of identifying beehives through "dance" movements, and the different structures of nests.

Bees are one of the insect groups that are beneficial to human beings. It pollinates crops, fruit trees, vegetables, grasses, camellia oleifera crops and Chinese medicine plants, and the yield can be increased by several times to 20 times. Honey is a tonic commonly used by people and has the reputation of "milk for the elderly". Royal jelly is a kind of advanced nutrition, which can not only enhance physical fitness and prolong life, but also treat chronic diseases such as neurasthenia, anemia and gastric ulcer. Bee venom is effective for rheumatism and neuritis. Beeswax and propolis are both raw materials for light industry.

All bees feed on pollen and nectar. Nectar can be converted into honey in the digestive tract. All female honey has a kind of thorn. Bees and giant bees (big round bees with black bodies) are both insects, but most of these bees live alone, and some live in other bees' hives and get food from other bees. A typical bee colony has a queen bee who can lay eggs and a female bee (worker bee) whose sex is undeveloped; There are also many fertile drones.

According to different species, the number of worker bees generally ranges from 12 to more than 50000. They collect nectar and pollen, and if they are bees, they send them to specific places. These nectar and pollen are obtained by dancing special and strict dances. Their duties include making honey, making wax beehives for storing food and living larvae, and taking care of bees and queen bees and keeping the beehives expanding. Bees are a perennial group. New queen bees will be kept. The old queen bee then left the hive with a group of worker bees and rebuilt her home elsewhere. Bees are very useful. Because they can also pollinate plants like insects.

There are many drones, and a group may be nearly a thousand. The only duty of the drone is to mate with the queen bee. When mating, the queen bee flies out of the nest, and the whole group of drones chases after it. It's called marital escape. The queen bee's marriage and mate selection are carried out through flight competitions, and only the winner can become a spouse. After mating, the drone's genitals fall off in the queen's genitals.

Bees don't like the smell of gasoline.

Bees are most afraid of foam, because once their wings touch foam, they will fall off because they are too heavy.

In a highway accident in the United States, a bee truck overturned and 8 million bees gushed out instantly. It was because the driver was stained with gasoline that he escaped. All bees feed on pollen and nectar. Nectar can be converted into honey in the digestive tract. All female honey has a kind of thorn.

Apoidea bee

The generic term for HYMENOPTERA, Insecta. The back plate of the chest can't reach the base of the wing, and the body has branches or pinnate processes, and the hind feet often specialize into bees that collect pollen. Adults are covered with villi, and there are pollen collecting organs composed of long hairs on their feet or abdomen. Chewing and sucking mouthparts are unique characteristics of insects. Totally perverted. About 15000 species are known all over the world, and about 1000 species are known in China. Many kinds of products or behaviors are closely related to medicine (such as honey and royal jelly), agriculture (such as crop pollination) and industry (such as beeswax and propolis). They are called resource insects.

Habit: bees lay eggs in the nest room, and larvae live in the nest room. The larvae living in groups are fed by worker bees, while the larvae living alone feed on female bees and are stored in the bee bread in the nest room. When the bee bread eats them up, the larvae mature and pupate, and emerge from the cocoon when they emerge. There are several generations in a year for domestic bees and 1 ~ 3 generations for wild bees. Overwintering with mature larvae, pupae or adults.

Female bees build nests, collect pollen and nectar, and store them in the nest room. Their life span is longer than that of male bees.

Bees feed on plant pollen and nectar. Food habits can be divided into three categories: ① polyphagia, that is, eating different families of plants or flowers of a certain color (not limited to plant species), pollen and nectar of wishful bees and Chinese bees. (2) Oligophagia, that is, feeding on flowers of related families and genera, such as alfalfa wasps. (3) Monophagy, that is, feeding only from certain plants or related species, such as cornflower bees. The flowers interviewed by various bees are closely related to the length of mouthparts: for example, species with short mouthparts such as Labiatae, Aphidae and Aphidae interview the open flowers of Rosaceae, Cruciferae, Umbelliferae and Ranunculaceae; However, due to the long mouthparts, sawflies, honeybees and other species use deep flower tubes to interview flowers, such as Leguminosae and Labiatae.

Lifestyle can be divided into three types: ① Sociality. Male and female worker ants live in the same nest, but there are differences in morphology, physiology and division of labor. Female individuals are large and good at spawning and reproduction; Males are smaller than females, specialize in mating and die after mating; Worker bees are small female bees with genital hypoplasia. They specialize in nesting, collecting food, feeding larvae, cleaning the nest room and adjusting the humidity of the nest. Italian bees and China bees are social species. Besides, there are bumblebees, tropical stingless bees and wheat bees. (2) being alone. The vast majority of bees live alone, that is, female bees nest alone to collect powder and store grain, and they have no "hierarchical" differentiation. Each nest room is open, the inner wall is coated with wax and other moisture-proof substances, and enough bee bread is stored in the room. Female bees lay eggs on the bee bread and close their nests. Larvae feed on bee bread in the nest. Most species belonging to this category are wild species, such as Aphidae, Aphidae, Formicidae, Tenebrionidae, Aphidae and Formicidae. ③ parasitism. Female bees don't build nests, but lay eggs in the host's nest. Larvae generally has a large head and upper jaw, which is used to destroy the eggs or larvae of the host.

The nesting instinct of bees is complex, and the nesting place, time and nest structure are diverse. The nesting time is usually in the flowering period of plants. According to the nesting site and nest texture, it can be divided into the following categories: ① Species engaged in social life take wax secreted by themselves as spleen, such as bees, stingless bees, wheat bees and so on. The nest room is hexagonal. ② There are the most kinds of nests in the soil, and the interior of the nest room is coated with a mixture of wax and saliva to keep the humidity of the nest room. (3) The ways of using plant tissues to build nests are more diverse. For example, LEPIDOPTERA can roll plant leaves into tubes to form nests and put them in natural cavities; Mylabris uses plant hair to make wart nests on the stems; Lupine and LEPIDOPTERA insects nest on the stems of dead plants; Some kinds of bumblebees nest under the litter of the forest; Wood wasps drill holes in wood to build nests, and so on. (4) Others, for example, the genus Myzus uses saliva to adhere to small sandstone to build nests, and the genus Myzus builds nests in the shell of slugs.

Beehives are generally scattered, but there are also similar bees that have been concentrated in one place for many years, thus forming a nest group. For example, the number of nests of hairy feet can reach dozens or even hundreds.

Geographical distribution The geographical distribution of bees depends on the distribution of nectar plants. It is distributed all over the world and has many tropical and subtropical species. The distribution of different subfamilies or genera has certain limitations For example, bumblebees in the bee family are mainly distributed in the north temperate zone and can extend to the Arctic, but there is no record of distribution in the tropics. Short-tongued bees are distributed in Australia; Trichogramma subgenus of Trichogramma of Meliaceae is only distributed in central Asia. Aphidae are distributed in tropical areas. Bees are distributed in different landscapes, and most of them live in desert grasslands, grasslands, forest grasslands, river valleys and mountains. Each landscape belt has a representative genus or species. For example, the ground bumblebee is a forest grassland species, the land bee is a typical grassland genus, and the wasp is mostly a grassland species.

Classification and evolution According to fossil data, a large number of bees have been found in the late Eocene strata of Tertiary. Its appearance is closely related to the prosperity of flowering plants in the late Cretaceous.

Apiioidea is close to melioidea in classification, and its ancestor may have originated from a branch of melioidea. However, due to different eating habits, morphological characteristics tend to differentiate. The evolutionary characteristics of bees are: chewing and sucking mouthparts to form powder collectors and branching hairs; Eat nectar and pollen in adult and juvenile stages; The emergence of groups and social lifestyles; Polymorphism and parasitism in superfamily.

In Insecta, bees belong to the advanced evolutionary group. The emergence of social life style, the transmission of "language" information, the method of identifying beehives through "dance" movements, and the different structures of nests.

Economic Significance Bees are one of the insect groups that are beneficial to human beings. It pollinates crops, fruit trees, vegetables, grasses, camellia oleifera crops and Chinese medicine plants, and the yield can be increased by several times to 20 times. Honey is a tonic commonly used by people and has the reputation of "milk for the elderly"; Royal jelly is a kind of advanced nutrition, which can not only enhance physical fitness and prolong life, but also treat chronic diseases such as neurasthenia, anemia and gastric ulcer. Bee venom is effective for rheumatism and neuritis. Beeswax and propolis are both raw materials for light industry. First of all, bees are selective about flowers when collecting nectar. Generally speaking, bees don't collect flowers that are in bud or just in full bloom. Its picking object is blooming flowers, because the content of nectar or secretion is rich at this time.

So how do bees find the source of honey?

Although there are different kinds of insect antennae, they all have activities such as looking for food, choosing hosts to lay eggs and looking for aliens. Function. Insects always swing their whiskers up and down from left to right, just like two antennas and radars, always receiving radio waves and tracking targets. This is because the antenna is an important sensory organ of insects, which has the functions of smell and touch. There are countless sensory organs on the antenna, which are connected with many nerve endings in the sensory fossa, and they are directly connected with the central nervous system. When stimulated by the outside world, the central nervous system can dominate insects to carry out various activities. The antenna of bee belongs to knee-shaped antenna, and its olfactory fossa is mainly distributed at the front end of antenna whip joint. With the help of tentacles, bees can smell the fragrance of various flowers and find nectar.

Second, the honey collection process (taking Gerbera jamesonii as an example)

The mouths of insects and bees belong to chewing mouthparts. Its mouthparts maintain a pair of left and right symmetrical knife-axe shaped maxilla, which has the ability to chew solid pollen and build a hive. The lower lip is elongated to form a slender tube with a long slot in the middle, which is helpful for sucking. If you put this small tube into the flower, you can suck honey continuously. Bees with such mouthparts can not only collect pollen, but also suck nectar.

Gerbera has more stamens, but bees will not be confused. Bees fly to the flower tray and collect honey layer by layer from the outside to the inside. It inserts a small tube along the bottom of the stamen, sucks nectar and picks one flower after another. In a pot of flowers, bees usually only pick three or four flowers and then fly to another pot of flowers, and the two colors are different. After picking flowers of all colors, the bees fly back to the first pot of flowers and carefully collect the honey-picked flowers again (as far as pot flowers are concerned). It moves lightly and continuously. Watching bees collect honey can be said to be a kind of beautiful enjoyment.

Bees collect not only honey, but also pollen. Its feet are its good helpers.

Among all kinds of insect feet, the tarsal joints of the hind feet of bees are particularly large, with grooves on the outside and long and dense villi around them, forming a "pollen basket". When bees shuttle through the flowers to collect pollen nectar, the hairy feet are covered with pollen, and then the pollen is combed off by the "pollen comb" on the tarsal bones of the hind feet and collected in the "pollen basket". Finally, fix the pollen into balls with honey. This kind of foot that can carry bee pollen is called powder-carrying foot.

Thirdly, worker bees will not directly enter the honey storage room after collecting honey and returning to the nest, but will be caught by bees that have emerged for about 4 days and stored in the honey storage room; Small worker bees also feed their young bees with honey mixed with pollen.
