Why didn t the insect mayfly, which has a lifespan of only one day, go extinct?

If the float dies, will it disappear?

Reasons why mayflies only live for one day:

1. Adult mayflies starve to death. In mayflies, the mouthparts and digestive system, including the stomach, have degenerated and cannot eat, so their physical strength is only allowed to be consumed for one day.

2. Mayfly larvae live in a variety of freshwater habitats, most of which exist in living water with moderate temperature and constant flow, a few can survive in saltwater, and one even survives on land, and adult life is generally spent in flight. It is found all over the world, except in Antarctica, high Arctic latitudes and some oceanic islands.

The reason for the short life of mayflies is mainly that their mouths have degenerated and they cannot eat, and mayflies can be said to be the shortest-lived insects. From the time of becoming an adult (at birth), it does not live for more than a day, and usually dies within a few hours. However, after mating, the adults lay their eggs in the water, but the larvae take 1 to 3 years in the water to become sub-adults, and the sub-adults crawl out of the water and shed their skin before becoming mayfly adults.

Mayfly metaphor. The mayfly is from "Hanshu Wang Bao Biography": "The cricket is in autumn, and the mayfly comes out in the shade." Yan Shigu notes: "The sound of the beetle is from, and the word is also made of beetle." ”

Usually a metaphor for tiny life, shallow and arrogant people or words, mayflies have an ancient and special shape, and are the most primitive winged insects, most of which are found in living water at a moderate temperature and constantly flowing, and a few can survive in salt water.

The life of the mayfly is only one day, life and death, although it is short, but it will strive to experience the growth period of its life, adolescence, reproduction, aging and death, a person's life is also a mayfly for the universe, but we still have to strive to live a good life in the present, the mayfly is a metaphor for a strong and optimistic person who lives in the present. <>

There are thousands of species on the earth, neither plants nor animals can escape death, there is an insect whose life lasts about one day, that is, mayflies, why do mayflies only live for one day?

This is because mayflies have slender and soft bodies, thin wings, wide and large forewings, smaller hind wings, and a mouth equal to white length, which cannot be used to eat food at all after adulthood.

Its six legs are so soft that it can barely be used to climb blades of grass. There are two whiskers dragging on the tail, which is longer than the body. Mayflies can only perform lifting movements, and have no strength to fly at all.

Therefore, it does not eat or drink all its life, and when it completes its reproductive mission with sufficient strength, it no longer has the strength to live. Therefore, there is also a saying that life and death are twilight.

Mayflies can only survive for one day, but in a biological chain, any tiny species has great meaning for existence. Because mayflies can eat the larvae of mosquitoes, and at the same time its presence also controls mosquitoes well. Mayflies can only be seen in some relatively clean places, so mayflies have also become a species for monitoring water quality.

I believe you can often hear such a sentence, mayflies are born and die at dusk, and do their best, so many people think that mayflies can only live for 24 hours, but this is just a description of the ancients. Mayflies go through 4 stages in the process of growth, and many mayflies can live for more than three years. If the time is shorter, you can live for a few months.

Because the ancients only observed the state of mayflies as adults, they thought that they lived for such a short time. At the same time, many mayfly larvae can be used as food for fish, if the mayfly disappears, so that the fish cannot grow normally, and the organisms that depend on fish for food begin to disappear in large numbers. <>

In nature, each link in the biological chain plays a very large role, and their existence also controls the local ecological environment very well, if a certain species begins to multiply, the number of organisms in the next level will be less and less. At the same time, although mayflies have a short survival time, they have been breeding for 200 million years, and they have also escaped the extinction of the dinosaurs, which is very suitable for them. <>

For writers, they often assign a certain meaning to a certain species. Mayflies have also become a symbol of their short life, but they have gone through a lot of hardships in the process of growing up, but they never want to give up. For everyone, there are 24 hours in a day, and there are many changes in these 24 hours.

Maybe they want to see this beautiful world. To feel the beauty of life, even if it is fleeting, it is not hesitated. I believe that this spirit also encourages many people to keep striving towards their goals in a limited number of days.

The meaning of any creature is to be a part of the natural world, and this creature still contributes its energy to the natural world.

It is to come to this world to see the magic and changes of this world, to increase one's knowledge, to experience the beauty of life, and to reproduce the next generation.

Experiencing life, in fact, life is also a lot of exciting things, and he can experience it well.

Because it cannot be fed, it has a short survival time.

The reason why mayflies can only live for one day is because the adult body is slender and soft, the wings are thin, and they do not feed, and their "mouth" has degenerated, so they will slowly lose their strength and gradually die.

The mayfly is one of the most primitive winged insects, with a body length of 3 to 27 mm, and usually lays eggs in water. The appearance of mayflies has a positive effect on biodiversity and provides food for most fish species.

People can live for about a year, but the adult stage is very short.

People now live to 100 years old is already complete, the environment is getting worse and worse, the actual life span of mayflies is one year, in the underwater larval stage to grow for one year, adult only one day. Naturally, this is the case, the cycle of heavenly principles, everything is fate, if you can see it, you will enjoy it, and if you can't see it, it will be torture.

In fact, mayflies are designed for love from head to toe. Its mouthparts have degenerated, and its gastrointestinal tract is nothing more than bubbles, which makes it lighter and more suitable for flying. Even if it is hungry, it cannot eat even liquid food.

Mayflies can simply be called flying sperm nests or ovaries. Eating and drinking is a complete waste of time for them. They have only one day to live, during which they must find a mate, mate and lay eggs, and die peacefully after completing their life's mission.

It's a wonderful day for mayflies (aka dayflies) that live and die for love during this day. To be more precise: it's all about reproduction.

Could it have spent its entire life miserably? In fact, mayflies also have the first half of their life as a larva. Its larval stage lasts for several months.

Mother mayflies lay their eggs in puddles, ponds, or slow-flowing streams, where the larvae will hatch. Because these tiny white worms are rich in protein, they become a delicacy for the birds. If you're lucky, they'll turn into adults after a few peels and can finally fly!

Even if it's just for one day. Mayflies feed on algae during the larval stage and convert food into glycogen to serve as a nutrient reserve for the adult day's activity. When mailboxes become empty and run out of fuel, they will also die naturally.

To put it more brutally: they were starved to death. If a mayfly mates surprisingly actively, it may only have enough fuel to sustain most of the day's flight.

Mayflies always get the job done – to pass on the lineage. Fortunately, they don't lament their short-lived growth. Only humans are sentimental about death, and no other animal would erect a monument to a tree of its own kind.

But who knows? Maybe one day is long enough. When this small insect of only a few millimeters finds another of its kind in such a vast world and mates with it, it should be exhausted, right?

In any case, their way of survival is very effective, as different species of mayflies have spread all over the world. Their lives are a testament to the adage that true love is priceless.

The mayfly is designed for love from head to toe, his stomach is full of bubbles, she only has one day to live, she is born for love, she will complete mating in one day, and then die for love, so to speak, it is starved to death, and their lives are all confirming the adage: true love is priceless.

Can I be your mayfly, and accompany you to the end.

Mating 46: , the heart is good, do you know the next time? Does our time album have time?

There I am! We're in the parent directory when you're velvet! When we were a teenager, did we have the goods at the bar?

I've already bought it, what's wrong, right? It's okay when we're teenagers, hahahahaha. You!

I'm a**, you! What about me at home? I, you!

I'm already in school when it's okay? Where am I in the bakery, the bakery manager recommended you for a week, and the payment has been transferred? Hmmm (

There is a huge difference in the lifespan between animals, such as the Arctic clam, the world's longest-lived animal, which lives to be 507 years, while one of the world's shortest-lived animals, mayflies, survives for only a few hours, and yet they still need to mate and reproduce in that short period of time. In ancient books, the term "life and death" was used to describe mayflies, which shows their short lifespan. However, the short lifespan refers to the adult worms of mayflies, and their larvae still have a survival time of several months to a year.

Mayflies are small to medium-sized insects, generally 3 to 27 mm long, with a slender and soft body, and adult bodies are often white and yellowish. They are primitive winged insects that are capable of flying through the air and have two pairs of wings with forewings larger than hindwings. Mayflies have a pair of long tail whiskers at the end of their abdomen, making them easier to identify.

The larvae of mayflies live in freshwater lakes or streams and have tracheal gills on their bodies for breathing, so they can adapt to life in the water. They feed on higher aquatic plants and algae, crawling or climbing through the water. The juvenile stage of mayflies generally lasts from a few months to 1 year, or even more than 1 year, and when they are fully grown, they will climb to the stones or plant stems at the water's edge, and emerge into sub-adults after sunset, and then emerge into adults after a day.

Adult mayflies do not have the ability to chew and cannot feed, and can only rely on the nutrient reserves in the body during the larval stage to support the rest of their lives, so their lifespan is very short, generally only a few hours to a day. During this short period of time, mayflies must find mates and complete mating to reproduce their offspring. When the fuel in their bodies is depleted, they will die naturally.

It can be said that the adults of mayflies are born for love and die for love.
