Mayfly has a slender body, a head that can rotate freely, two pairs of wings, well-developed forewings, and small hindwings; The abdomen is elongated, with a filamentous tail hair that is longer than the body. The lifespan of adults varies depending on the species, ranging from very short to a few hours, and the longest can be as long as 821 days, usually 23 days. Therefore, in the idiom, the life and twilight death refer to the life of the mayfly after it has changed from a juvenile to an adult.
Mayflies lay eggs in the water after mating, usually hatching in one or two weeks, and the larvae look very similar to silverfish, and some are very similar to tadpoles; It has tracheal gills on the abdomen and lives in water, living on microorganisms and plant tissue fragments in the water. The juvenile period is very long, and some have to shed their skin more than 20 times before becoming adults.
You may think that epiphany is the shortest-lived flower, right? No. The king lotus of the Amazon River in South America shows its face in the early morning and wilts in half an hour. The shortest-lived flower in the world is the flower of wheat, which blooms for only five to thirty minutes before it is gone.

Organisms include animals, plants, microorganisms, fungi, bacteria, and viruses.
The short life span of a mayfly refers to its short adult lifespan (a few hours to a day) and a longer larval lifespan (several years to 1 year for the larvae, similar to cicadas, and 1 month for adults).
Therefore, among living organisms, bacteria and viruses have the shortest lifespan.

Yes, microbes, they have a lifespan of a few milliseconds or even less!

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.

The lifespan of adult mayflies is only a few hours to a few days, so there is a saying that "life is born and dies". Mayflies are a primitive and beautiful class of insects that originated in the Carboniferous period and are at least 200 million years old, and are the most primitive winged insects.
Mayfly. Mayfly insects are slender and soft, usually 3-27mm in length, short antennae, developed compound eyes, large mesothorax, developed forewings, vestigial hindwings, a pair of very long tail whiskers at the end of the abdomen, and some species also have **tail filaments.
Mayfly larvae live in a variety of freshwater habitats, most of which are found in living water at moderate temperatures and in constant flow, a few can survive in saltwater, and one even survives on land, and adult life is generally spent in flight.
Adult mayflies are often active near streams, beaches and lakes, and can be used to detect the type and degree of pollution of water according to their adaptation and requirements to waters.

Mayflies are considered to be the shortest-lived animals on Earth, with a lifespan of only 24 hours. This insect belongs to the category of aquatic animals. Mayfly immature life forms are produced in almost completely clean fresh water.
There are about 3,000 species of mayflies on Earth, and their lifespans range from 30 minutes to a day.
Scientists even believe that the main purpose of the existence of this life is to reproduce, which is very alarming. Because some species of mayflies die after birth, ...... before they have time to eat a few bites of foodIn addition, Dorania of America is considered to be the shortest-lived type of mayfly, with a lifespan of only 5 minutes.

Adult mayflies live for about 1 day Most of the time, they are busy laying thousands of small eggs in the shallow streams of mountain streams, although there are hungry trout.

Adult mayflies live for about 1 day.

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. <>

One day. Mayflies are known as the shortest-lived animals in the world, mayflies have ancient and special traits, and are the most primitive winged insects and Nymphs can be divided into the same class of ancient wings, and their wings cannot be folded. Bee butterfly insects are slender and soft, with short antennae, well-developed compound eyes, large mid-chest, well-developed forewings, vestigial hindwings, a pair of very long tail whiskers at the end of the abdomen, and some species also have **tail filaments, vertebrates are aquatic, and adults do not feed.

If the float dies, will it disappear?
Life expectancy is partly related to genetic factors, but the impact of a life partner on longevity is more important than family genetic factors. The heritability of human lifespan is not between 15% and 30%, but it is likely to be less than 10%, and it is the life partner who will really affect the lifespan. >>>More
