Are there black spots on bee wings? What species of bee with dark spots on its wings?

Hello, glad to answer for you, there are small black dots at the base of the bee's wings.

Nie Li, a primary school student, discovered that bees do not make sounds by vibrating their wings.

Wuhan, November 18, 2003 (People's Daily Online) -- Recently, the deputy county magistrate of Jianli County, Hubei Province, came to the Central Primary School of Huangxiekou Town, visited a sixth-grade primary school student named Nie Li, and asked her a question: What do bees rely on to make buzzing sounds?

The bee has its own articulatory organs, and it does not make sounds by vibrating its wings. Nelly said.

In mid-August, at the 18th National Youth Science and Technology Innovation Competition held in Lanzhou City, 12-year-old Nie Li wrote a scientific ** "Bees Do Not Rely on Wing Vibration to Make Sounds", which won the silver medal of the competition's outstanding scientific and technological projects and the Coats Science Special Award.

This conclusion was reached after more than a year of observation and experiments on bees.

In the autumn of 2001, Nie Li learned from the book "Natural Learning Tutoring for Primary Schools" that bees, flies, mosquitoes and other insects are mute, they have no articulatory organs, but they have wings that can call, and these insects constantly stir their wings at high speed when flying, causing the air to vibrate, so that they produce a buzzing sound. Later, Nie Li also saw in "One Hundred Thousand Whys" that the buzzing of bees comes from the vibration of their wings, up to 200 times per second, and if the wings stop vibrating, the sound also stops. She asked her teacher for confirmation, and the teacher's opinion was the same as in the book.

Last spring, Nie Li went to play in an apiary and found that many bees had gathered on the beehive, their wings were not stirring, and they were still buzzing, so she questioned the textbooks, popular science books and teachers' explanations, and began experimenting and researching bees. She first glued the bee's wings to the wooden board, and the bee still made sounds. She cut off the wings of the bees and could hear the bees.

The two methods were alternated 42 times, using 48 bees each time, and the test results showed that bees could make sounds without vibrating their wings. For the sake of the bee's articulation organs, she glued the bee to the wooden board, carefully searched it with a magnifying glass, observed it for more than a month, and finally found two black dots smaller than rapeseed at the base of the bee's wings.

She pierced the little black dot with a pin, and the bee stopped making a sound. She also brought in some bees, which did not damage their wings, but pierced small black dots and put them under the mosquito net. The bees flew around and there was no sound anymore.

She repeated the test 10 times, and the results were the same. She wrote about this discovery as **, believing that the bee's articulatory organs are these two small black dots.

It is reported that Nie Li's ** has been included in the collection of award-winning works by the organizing committee of the competition, and the journal of the China Education Association and the Primary School Nature Teaching Professional Committee has also published Nie Li's ** in full.

Yes Sealing is just using small dots to make a buzzing sound.

A common name for insects of the family Xylocopidae. Medium and large bees belong to the family Honeybees. The body is stout, black or blue-purple with a metallic luster.

The thorax is densely hairy, and the back of the abdomen is usually smooth. Antennae are knee-shaped. The monocular is arranged in a triangular shape.

The upper lip is partially exposed, and the lower lip is long and tongue-in-cheek. The foot is thick, and the surface of the tibial joints of the hind foot is covered with dense brush-like hairs;The tibial joints of the anterior and midfoot are 1 distance and the hindfoot are 2 distances. The wings are long and narrow, often irident.

The abdomen is sessile, and the female has a stubby spine at the end of the tail in the hair. The camp lives alone, often bored in the dry wood of the nest, the nest is 1 row, and the wall of the chamber is made of sawdust, plant fragments, etc. mixed with saliva. It is very harmful to timber, bridges, buildings, fences, etc.

Yellow-breasted carpenter bee (xylocopapendiculata), 24-26 m long. Black. The upper jaw has 2 teeth.

The hind foot has a tibial substrate lateral to the base of the tibial joint. Yellow hair on the chest;The tibia and basal ganglia are black hairs.

No one is currently named.

It was an inadvertent discovery. Nie Li, a primary school student in Jingzhou, Hubei Province, went to the apiary to play and found that bees did not vibrate their wings and could make buzzing sounds, which was obviously different from what was written in the book!Nie Li handed over the question to Deng Congxin.

Deng Congxin did not come out, but he did not arbitrarily say that it was impossible, but encouraged Nie Li to do experiments and research on his own. There were not enough bees for Nie Li's experiments, so Deng Congxin also went to the Huanghu Farm more than ten kilometers away and caught more than 100 bees at a time from the beekeepers to ensure sufficient experimental materials.

After verifying more than 2,000 bees in 42 experiments, Nie Li concluded that all bees have a small black dot smaller than rapeseed at the base of their wings, and when the bees make sounds, this small black dot keeps agitating up and down. The articulatory organs of bees are not wings, but these two small black dots at the base of the wings.

Related works have been published in the journal Natural Sciences Scientists are working on.

The little black dots are the important things.

If these two vocalizations are used, they should be called vocal organs. But now it seems to be called the black dot at the base of the wings.

It may be entered by taking honey or filling, but such honey has been contaminated and it is not recommended to continue to consume it, and good honey has gone through procedures such as filtration and testing to avoid this situation.

Worms. The scientific name of this insect is worm, the common name is also called money string, millipede, this insect can secrete venom, natural honey is good, but many of them have secondary pollution, beekeepers' hygiene habits are really important, it is not recommended to continue to drink, although it is not enough to have any impact on human health, it is not recommended to continue to drink.

It used to be thought that way – the buzzing of bees comes from the vibrations of their wings, up to 200 times per second. But not anymore: The biological community has long believed that bees have no vocal organs and can only make sounds by vibrating their wings.

However, a schoolboy named Nie Li proved with experiments: "Bees have their own vocal organs, and they do not make sounds by vibrating their wings." Not long ago, at the 18th National Youth Science and Technology Innovation Competition held in Lanzhou City, 12-year-old Nie Li wrote a science **.

Bees don't make sounds by vibrating their wings" won the Silver Award for Outstanding Science and Technology Projects in the Competition and the Coats Science Special Award. At the base of the bee's wings there are two black dots smaller than rapeseed, and when the bee calls, the black dots agitate up and down. Think that the vocal organs of bees are these two little black dots.

Honey bee is a general term for insects of the family Honeybee, and there are many species of black bees, and the common ones are as follows:

1. Northeast Black Bee.

Northeast black bee is the only local excellent bee species in China, there are 2 types of queen bees, one is all black, the other is the abdomen 1 5 dorsal plate with brown rings, the worker bee has 2 types, one is the chitin is all black, the other is the two abdominal segments on both sides of the dorsal plate with smaller macula and the villi on the dorsal plate of the thorax are yellowish-brown, and the drone has only one black body color.

2. Big black bee.

The black bee is the largest bee of the genus Honeybee in the bee family, mainly produced in the snow-capped mountains around the Himalayas, the abdomen of the worker bee is slender, the abdomen is all black brown, the length and width of the head are equal, the lip base and the forehead are slightly raised, the thickness of the engraved points on it is uneven, the drone's compound eyes are large, the top is connected, brown, the antennae whip is black, the chest and abdomen are black, there are no reddish-brown markings, mainly interview Rhododendron and other plants.

3. Black bees.

The body of the queen bee is black, the upper jaw is brownish-yellow, the antennae are black, the dorsal plate of the midthorax is black, and the feet are black. The drone is black, and the base and tip of the palate are black.

4. Bumblebee. Bumblebee is a kind of polyphagous social insects, stout, medium to large, the whole body is densely covered with black, yellow or white, fiery red and other long and neat hairs, in our country is very widely distributed, only a few places are not found, its life history and bee life history is very different, most places are a generation a year, there are a few places is a year two generations.

5. Carpenter bees. Carpenter wasp is a large species in the general family of bees, named because most species nest in the wooden structure, the body is stout, black or blue-purple with metallic luster, the chest has dense hairs, the back of the abdomen is usually smooth, the camp lives alone, often bored holes in the dry wood to camp the nest, the nest is 1 column, made of sawdust, plant fragments and other saliva mixed with the wall of the chamber, which is very harmful to wood, bridges, buildings, fences, etc.

There must be black bees in the bees, and the color of the bees is mostly the same as the yellow and yellow we usually see, and the black ones you said are only a very few, but there must be, and there are genetic variations! I've seen it before.
