Dragonflies seem to be docile, why do they become a strong species among insects?

Many people will see dragonflies in some grass or parks, and they think that dragonflies are very docile. But the dragonfly is a strong species among insects, and it is also the king of the flying world, so there are many mysteries on the dragonfly. Especially in childhood, seeing dragonflies makes people very curious.

There are also many people who go to roll cobwebs to catch dragonflies, which is also a childhood memory. The insect may look light and cute, but it is also an apex predator. There are a lot of nicknames, so many scientists also do research on dragonflies.

If you've ever caught a dragonfly, you'll know that it's very difficult to catch a dragonfly without mastering the skills. Because dragonflies are very skilled in flying, they can fly around, such as up, down, left, and right. And it is very flexible in changing direction, and it can hover in the air, which is also very outrageous.

And dragonflies can fly very far at a time, up to 5,000 kilometers. You can also cross the Pacific Ocean, so you can also go. <>

The reason why dragonflies are so capable of flying is that their wings are very light and tough. Ordinary insects have two wings, but dragonflies have four wings. And it is distributed on both sides of the body, which is very symmetrical, and the area is large and thin.

There will also be a lot of textures, so it looks very beautiful. Dragonflies have very large and thin wings, so the energy consumption of them can be reduced when flying. Many people may see that dragonflies have thin wings and think that they are very fragile.

But it's actually very tough, because these lines are the meridians of dragonflies. The meridians will divide the wings, such as hexagons and pentagons, so that the stability of the structure can be guaranteed. And for dragonflies with very high intensity flight, it can also be supported.

Dragonfly wings are not easily contaminated with oil, dust, and water, and their predation ability is also very strong. Although it is not that large, it is usually very sensitive to prey on mosquitoes and flies. If you are caught by a dragonfly, then there is no way to escape.

Dragonfly is one of the most powerful insects, and although it is small, it is very observant of its surroundings.

Dragonflies are known as the "kings of flight", and their speed of about 100 kilometers an hour is almost the speed of a cheetah running at full speed. The running of a cheetah is not long-lasting as compared to a dragonfly as a dragonfly can fly continuously for an hour, whereas a cheetah can only run continuously for a shorter period of time.

Because the flying speed of dragonflies is very fast, and they can also make some very difficult movements of blood and sharp turns, their eyesight is also very good, and they also have good mobility.

Dragonflies can also fly very far distances at a time, and it has long been observed that some dragonflies can migrate across the reborn Indian Ocean to Africa, and in 2016, a study by scientists at Rutgers University showed that there is a thin-winged dragonfly that can cross the Pacific Ocean and can fly up to 6,440 kilometers.

It is"Mayfly".Mayflies.

Commonly known as mayflies, they have an ancient and special shape and are the most primitive winged insects. It can be divided into the same class as dragonflies, and their wings cannot be folded. Mayfly insects are slender and soft, usually 3-27mm in length, short antennae, developed compound eyes, large mid-chest, developed forewings, vestigial hindwings, a pair of very long tail whiskers at the end of the abdomen, some species also have **tail filaments, juveniles are aquatic, adults do not feed, and the life span is very short, the shortest is only one day.

Adult mayflies don't eat, and after molting, their digestive tract fills with air — before the last molt, the midgut heals to form a closed, sausage-like balloon. It's filled with air, which allows the larvae to float to the surface of the water easily. 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.

It is found all over the world, except for Antarctica, high Arctic latitudes, and some oceanic islands [1].

Scientific name in Chinese"Mayfly".

Dragonflies are insects. Dragonflies are the insects with the most eyes in the world. Dragonflies have large, bulging eyes that occupy the majority of their heads, with three monocular eyes and compound eyes consisting of about 28,000 small eyes, which have excellent eyesight and can look up, down, forward, and backward without having to turn their heads.

In addition, their compound eyes can measure speed. When an object moves in front of the compound eye, each "small eye" reacts in turn, and the speed of the target object can be determined after processing. This makes them masters of insect catchers in the insect world. Its chewing mouthparts are well-developed and powerful.

Dragonflies are a type of insect.

Dragonflies, invertebrates, phylum Arthropods, Insecta, Winged subclasses, Dragonflies, Paraptera, Dividing Dragonflies and Flyflies. Generally large, with long, narrow wings, membranous, reticulate wing veins with extremely clear veins. Extremely sensitive vision, 3 in one eye; antennae 1 pair, thin and short; Chewing mouthparts.

The abdomen is elongated, flattened, or cylindrical with an anal appendage at the end. The feet are thin and weak, with hooked spines that catch pests while flying through the air. The larvae (larvae) develop in water and breathe with the rectum and tracheal gills in the water.

Generally, it takes more than 11 molts, 2 or more years to crawl out of the water along the aquatic weeds, and then finally molt and emerge into adults. In the water, larvae can prey on animals or other small animals, and sometimes cannibalism of their own kind. Adults generally fly in ponds or rivers to prey on flying insects.

In addition to a large number of mosquitoes, flies and other harmful insects, some can also prey on butterflies, moths, bees, which are beneficial insects. There are more than 5,000 known species of dragonflies.

Dragonflies are a type of insect. Dragonfly is a generic name for invertebrates, insects, dragonflies, and suborder Paraptera.

The base of the hindwings is slightly larger than the base of the forewings, and the wing veins are slightly different. When resting, the wings lie flat on the sides. The larvae are short and thick, with rectal gills and no caudal gills.

There are 3 general departments, including Aeshnidea, Cordulegastroidea, and Libelluloidea, with a total of 11 families. Flyflies and dragonflies are the most common and are widely distributed throughout China.

The role of the dragonfly:1. In addition to preying on mosquitoes and flies in large quantities, adults can also prey on pests such as butterflies, moths, and bees, which are beneficial insects.

2. In terms of medicinal use, it can tonify the kidney, detoxify, relieve cough, relieve sore throat, etc.

Dragonflies are beneficial insects. Young insects can prey on cockroaches or other small animals in the water. Sometimes, insects of the same species also eat each other.

Both adults and larvae are carnivorous, and eat more pests. Adults can prey on mosquitoes, flies, and some can also prey on butterflies, moths, bees and other pests, which are actually beneficial insects.
