From the point of view of the beholder, it seems obvious that the moth will be attracted to the light; But in fact, it would be more accurate to say that the moth hovers around a bright object "because the moth is dizzy and can't figure out the direction". Moths use light as a compass to navigate, and have evolved to use fixed parts of their eyes to receive light. As long as the light source is very far away, such as the sun or the moon, the angles of the light received in the moth's eyes will be nearly uniformly parallel, and the moth will only need to travel in a straight direction, and the visual image will remain the same.
But when the light source is very close, if the moth is still traveling in a straight line, the angle of the light it receives changes at each moment it moves. So in order to adapt to this change, the moth will appear to be spiraling towards the light source from the beholder. <>

Among insects, moths are the sister of butterflies and belong to the order Lepidoptera, the suborder Heterogeneus. Moths though not. There are butterflies that are pretty, but they reproduce in a similar way.
On the body of the female moth grows a special chemical called extrasexual hormones. Through the diffusion of extrasexual hormones, male moths are attracted from distant places and mated. Although the amount of extrasexual hormones secreted is small, the effect is large.
It is said that a female dance moth can attract 1 million male moths as long as it secretes micrograms of extrasexual hormones. Male moths have particularly well-developed olfactory organs, and their antennae tend to grow into feathers or ctenophores, so they are very sensitive to the extrasexual hormones released by female moths, and can almost sense information with only a few molecules. When the wind speed was 100 centimeters per second, the male moth still responded to the extrasexual hormones of the female moth thousands of kilometers away, but lost this response after removing the antennae.

<> moths and their close relatives butterflies, commonly known as lepidoptera, have wings that are structured in ...... like the above
Transparent wings with several scales stuck in them, each of which is so small that it looks like powder when you put it in your hand. Hence the name "Lepidoptera".
Please noteThis scale is not the same thing as a human fingernail or somethingIt is disposable and extremely easy to shed.
Objectively,These scales can reflect from different angles, interfering with the sun's rays, which allows us to see that their wings are colorful。[Correspondingly, the insects that pollinated the first pollinators, in order to obtain protective color, deliberately made more excellent hormone cells on their wings (such as leeflies), and it turned out that the color combination of wings was not as many as that of Lepidoptera.] Of course, when encountering a spider web, a large number of scales first get on the spider silk and fall off, which also gives the insect a small chance to break free directly.
So you know.
Normal moths don't die, and their wings are actually transparent. It's just that these scales, which are easy to peel off, make it look "as if" they have a variety of colors.
We can see that his wings are transparent, but in fact he has been hit by a severe mechanical blow (such as when you poke him with your hand), which caused a large area of scales to fall off from his body. In fact, even when he is alive, you can twist all the scales off his body and turn him into a transparent moth.

The wings of insects belong to the appendages of the body, similar to fingernails, and can be transparent.

Moths flying around is actually a common natural phenomenon. In life, we often see all kinds of insects flying around, and moths are one of them. However, the fact that moths fly around is often interpreted as meaningful, so what does this portend?
First of all, the moth flying around may represent some kind of transformation. Moths go from caterpillars to pupae to adult moths and go through a process of metamorphosis. Therefore, when a moth suddenly appears around us, it may be a sign that we are about to face some major change.
This change can be good or bad, but we need to look for opportunities in this change.
Secondly, moths flying around us may also suggest that we need to work harder to pursue our dreams. Moths usually fly diligently because they need to find a light source. In the same way, when we pursue our dreams, we need to constantly put in the effort and keep looking for the way forward.
Moths tell us that we can only achieve our goals if we keep moving forward.
Finally, the moth flying around it may also be a symbol. Moths are usually black or gray in color, so they are sometimes interpreted as a symbol of mourning, melancholy, or gloom. However, there are also those who believe that the moth rock barrier instead represents happiness, wisdom, and mystery.
This symbol varies from person to person and needs to be interpreted according to the individual's actual situation.
In short, the moth flies around, what exactly does it mean, it needs to be comprehensively analyzed according to the actual situation. But whether it's a change for good or a bad, whatever the symbol, we can all draw some inspiration from it to make ourselves better.

Moths are insects, and insects have two pairs of wings, which are not called wings.
The moth has two pairs of wings.

It's all here.
1) Eggs. Milky white, very small, about 1-2 mm long, millimeters in diameter, oval in shape. The egg has an egg shell on the outside, which is relatively thin and plays a protective role, and the egg fluid is a white milky mucus. Eggs are divided into: egg shell, nucleus, yolk, protoplasm.
2) Larvae. Yellow and shiny, about 35 mm long and 3 mm wide, cylindrical in shape. There are thirteen verses.
The joints of the joints have yellow-brown rings. The ventral surface is pale yellowish. The proportion of the cephalothorax to the body of the worm is shorter, about 1 5 of the body.
The body is straight, **firm, and thick in the middle. The distal segment of the abdomen is smaller. The head seam is U-shaped, and the mouth is flattened.
The caudal process is pointed, curved upward.
3) Pupa. After the larvae grow to 50 days, they are about 2-3 cm long and begin to pupate. The pupa has a large head and a small tail, the head is basically the same, and the two legs (thin wings) are close to the chest.
The sides of the pupa are serrated and angular. The pupae are white and translucent at first, with a soft body that gradually turns brown and then hardens.
4) Adults. Pupae over 25 and molt into adults after a week. The adult worm has just molted and is milky white, the carapace is very thin, and after ten hours it becomes yellowish-brown, black-brown, shiny, oval-shaped, about 14 mm long and 6 mm wide, and the carapace becomes thick and hard, and it is fully mature.
After mating, eggs are laid for the second generation of reproduction. The body of the worm is divided into three parts: head, thorax, and abdomen. The adult head has one more pair of tentacles than the larval head and is five times as long as the larval face.
There are three pairs of feet, one pair on the anterior thorax and two pairs on the abdomen, which are 8 to 10 times longer than the larvae. Each toe has two hooks and hairs on the toes. There are several vertical stripes on the wings on the back.
Although the adult has a pair of beautiful wings, they can only fly short distances, and the wings protect the body on the one hand, and help crawl on the other.

There are many types of floaters. Yes, yes**. Some are permanent, while others disappear from view over time.
Therefore, floaters are not the turbidity that everyone simply imagines. Careful examination and identification of ophthalmic tripod mirrors or anterior mirrors is required. Let's think about the best countermeasures.
The drug** is iodine. (including ophthalmic and oral medications).
Floaters are physiological and pathological, both of which are due to changes in the vitreous. Physiological floaters are caused by the projection of the inherent formed components in the vitreous body on the retina that are seen by us, and are mostly translucent, with various shapes such as dots, strips, and reticulations. It is noticeable in bright light, but it is often not visible in low light.
Many people have this kind of floaters, and it has existed for a long time without change, and there is no need for **. Pathological floaters are caused by vitreous fundus diseases, such as vitreous opacity, inflammation, hemorrhage, parasites, etc., which often occur suddenly, and there will be changes in a short period of time, and sometimes it may be a prodromal symptom of retinal detachment, and it is necessary to go to the ophthalmologist for detailed examination. If you've had floaters for 2 years, there's a high chance of physiological floaters.
However, eye pain and vision loss are not accompanying symptoms of floaters. Go to the hospital to check for other eye diseases such as refractive error, dry eye disease, glaucoma, etc.
What the eye sees is not necessarily true, maybe he has other problems.
1. It is necessary to quit daily bad behavior habits, such as: do not squint to see things, wear glasses if there is myopia and astigmatism, and correct vision; Don't blink too often; Don't ignore the puffiness of the eyelids, check **, and prescribe the right medicine; If you want to be gradual, because of the sudden weight loss, there is not enough time to adapt to the loss of body fat, which will also cause wrinkles; Do not pull hard when removing makeup**; In a dry environment, you should replenish water in time, otherwise wrinkles will increase. >>>More

In the scorching summer, I ate too much watermelon, and there were more sayings. Some people think that eating watermelon is on fire because they are constipated after eating too much watermelon, and some people think that eating watermelon is bad because they have diarrhea after eating too much watermelon. Nutritionists say that watermelon is sweet and cool, clears heat and detoxifies, removes annoyance and quenches thirst, has diuretic effect, is rich in nutrition, and is a good food for summer heat, and will definitely not cause fire. >>>More
