Bees (bees/bees) belong to Hymenoptera and Apidae. Bees originated in Asia and Europe and were brought to America by British and Spanish. Bees belong to Hymenoptera and Apiidae. There are three kinds of bees, one is in a tree; One kind used by people with utensils is the domestic bee, which is small in size, yellowish and rich and sweet in honey; There is a kind of bee, which nests in a high and steep place on the rock, called Shimi. This kind of bee is as black as a gadfly, and its honey tastes sour and red. Bees live entirely on flowers, including pollen and nectar, sometimes brewed and stored as honey. There is no doubt that bees are pollinating it as well as collecting pollen. When bees collect pollen between flowers, they will drop some pollen on the flowers. These fallen pollen are very important because it often causes cross-pollination of plants. The actual value of bees as pollinators is greater than the value of making honey and beeswax. 8-20 mm long, brown 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, the mouthparts are chewing and sucking, and the hind feet are powder-carrying feet; Two pairs of membrane wings, the front wing is big and 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 go through four stages: eggs, larvae, pupae and adults. There are about 1.5 million species of bees in the world, and there are about 1.000 species in China.

Basic introduction

Bees are invertebrates with hard and segmented shells. The internal organs of bees are soaked in bloody lymph, which is a liquid with blood function. Bloody lymph is colorless and flows through the body with the help of the dorsal tube that acts as the heart. Because bees have no vascular system, blood-bearing lymph flows freely in the body driven by the dorsal tube.

Load bees

The body of a bee is a small and perfect machine. Bees have the same respiratory organs as other insects. The multi-branch bronchial system delivers air to all cells. The trachea is connected with the outside world through 20 valves (3 pairs of chest and 7 pairs of abdomen).

Digestive organs are pipes from the mouth to the anus. The head is pharynx, the chest is esophagus, and the abdomen is crop (for storing and transporting food); Followed by the anterior cavity, stomach cavity and intestine, the anterior cavity is like a one-way valve, which only allows food to flow from crop to stomach cavity and not vice versa; At the end of the digestive organ is the anal pouch. In the whole digestive organ, food is digested by digestive juice. The anal bag is located at the end of the abdomen, which is huge and can store the excrement of bees all winter.

Bees have very developed senses, especially vision. With the help of five compound eyes and three monocular eyes, the viewing angle of bees is almost 360 degrees, but their visual acuity is only 80% of that of humans, although it is higher than that of many insects. Bees are highly astigmatism, so their perception of vertical movement is better than that of horizontal movement. The continuous vision of bees is 300 frames per second (24 frames per second for humans), so for bees, a movie is just a series of still pictures. However, if humans want to see the action of bees clearly, they can only use the slow motion of hand movies.

Bees see different colors from humans, too. The colors that bees can see are: yellow, orange, yellow (human yellow-green), blue-green (human has no corresponding color vision), blue (human blue and purple) and ultraviolet rays that human can't see. The reason why Yumei attracts bees is not because its flowers are red, but because it can reflect ultraviolet rays.

Bees have a keen sense of taste. They can distinguish sweet, sour, bitter and salty tastes. The taste of bees is related to different parts of their bodies. We can distinguish the taste of bee's mouth, the smell of tarsal bone on the tarsal joint at the end of foot and the smell of tentacles on the last 8 nodes of tentacles. However, bees taste different from humans. For example, human beings feel that lactose is sweet, but bees don't feel sweet. In addition, the taste ability of bees depends on age, physiological status and nutritional status, the latter is the most important. So bees are sensitive to weak sweet concentration when they are hungry, but they don't feel this concentration at all under normal circumstances. The tentacles of bees have the functions of both ears and nose. The antennae of bees are divided into three sections. The third paragraph is the longest, 1 1, and each paragraph has a small plate with you as the receiver. Some receptors feel smell, and some receptors feel sound or vibration more accurately, because people think bees are deaf, but they are very sensitive to vibration. Vibration receptors are filamentous, each with 8500 antennae. There are densely perforated sensory plates (3,000-6,000 for worker bees, 3,000 for queen bees and 30,000 for drones) and "cone-bottom" receptors on the second and third segments of the antenna. Bees seem to have the ability to feel a certain smell, even if it is mixed with several other smells; But bees can only smell the flowers at a relatively close distance. However, the sentry standing guard at the door of the hive distinguishes between compatriots and intruders by smell. In addition, when worker bees dance to convey the information of honey source, it is impossible for dancers to be seen by their companions, because they dance in the dark, so their companions perceive it by touch, hearing and smell.

Development characteristics

Bees are completely abnormal insects, which go through four stages of development: egg, larva, pupa and adult.
