Dragonflies have a 95 success rate, why is it so powerful? What does it have to do with it?

It is because the dragonfly has a strong sensory ability, the dragonfly is a carnivore, about 300 million years ago, this animal has appeared, the dragonfly can fly at a speed of 54 kilometers per hour, it is an animal at the top of the food chain, and it does not make serious noise during flight. It has something to do with the biological properties of this animal.

The dragonfly flies at a particularly fast speed, and its wings and wings are particularly long, and its eye-catching abilities are particularly strong; This is very closely related to its ability to fly and its body structure.

This is because dragonflies do not make any sound during the flight process because of the construction principle of their wings, and the success rate of hunting is very high.

This is related to the wings of the dragonfly, and the wings of the dragonfly can not make a sound during the flight, so the hunting efficiency is very high.

<> "If you ask which animal in the animal kingdom has the highest hunting success rate?" I believe that many people will think of large carnivorous animals such as leopards, lions, and tigers. But scientists point out that the dragonfly is the world's best hunter when it comes to catching prey, and the winged insect has a success rate of more than 95 percent in catching its target prey, which is twice as much as the great white shark and four times as successful as the king of the jungle, the lion.

Dragonflies eat mosquitoes and other small insects such as flies, bees, ants and wasps, and occasionally catch butterflies, which can often be found over swamps, lakes, ponds, streams and wetlands in search of targets. The reason why the dragonfly is such an efficient hunter is that once it has identified its prey to hunt, it will always keep the prey in its line of sight, constantly adjust its flight path, and be able to ** the movement of the target before taking action.

Scientists at the Howard Hughes Medical Institute in Virginia, USA, compared the insect's movements (about its own movement and the movement of its targets) to those used by ballet dancers to keep pace with their companions.

This is the first instance of an invertebrate animal possessing this skill. As the dragonfly rests quietly on a leaf, patiently waiting for its prey to fly overhead, its big eyes see the world almost spherical. When the time is ripe, it quickly takes off, begins the pursuit, and uses its furry legs to capture its victims in an instant.

The dragonfly's keen vision and lightning speed (because it has special neurons that help it detect the movement of its target and direct its wings to respond in a timely manner) make it a formidable hunter.

The high-speed measurements show us how dragonflies rely on their visual responses to determine the position of a fly and manipulate itself to quickly fly to its target. Scientists attached tiny reflection markers to the dragonflies, used motion capture technology to record the insect's movements at 1,000 frames per second, and replayed the footage 20 times slower than the original film to analyze their tiny movements.

This video confirms that the dragonfly's actions are made by combining the movement of the prey with a visual response. This allows it to estimate the position of a fly and determine how its wings and head need to move when catching prey. To avoid detection, dragonflies approach their targets from below, keeping their bodies parallel to the direction of movement of their prey.

Its body and head are capable of independent movement, with the latter locking onto the target and its body taking it to the best position to attack.

The findings, published in the journal Nature, point out that dragonflies' manipulation behavior is more complex than previously thought, but it remains to be seen whether this is also the case in other invertebrates. Anthony Leonardo said: "The study highlights the important role that internal patterns play in the construction of such complex behaviors in this animal.

It is beginning to reshape our perception of the neural basis of this behavior. ”

Dragonflies are carnivorous insects. Dragonflies prey on a variety of agricultural, forestry and animal husbandry pests such as flies, mosquitoes, leafhoppers, midges and small butterfly moths. Dragonflies are an important class of natural enemies that are beneficial to humans.

"Dragonfly spot water" is the biological characteristic of dragonflies laying their eggs in water Its larvae (larvae) live in water, and the life period varies depending on the species, and the dragonfly is generally 2 years, and some are as long as 3 to 5 years.

Dragonflies are well-known insects, with more than 5,000 species known worldwide. China is an important dragonfly resource country in the world, with more than 980 species discovered, which can be called the world's largest, among which a large number of endemic and endangered species have extremely high conservation value.

Dragonflies "breathe" through a system of stomata on their bodies, rather than indirectly absorbing oxygen through the bloodstream, which is connected to the trachea and sends oxygen throughout the body from top to bottom by layer of smaller and smaller stomata.

At current oxygen levels, the total length of the modern dragonfly stomatal system has reached its limit; Beyond this limit, oxygen levels become insufficient. As a result, in a high concentration of oxygen, the total length of the dragonfly stomatal system will be longer and larger.

Dragonflies live in water when they are young, and their jaws are well developed, which can prey on creatures such as babies, aquatic insects, small aquatic animals, tadpoles, and small fish.

Adult dragonflies have degraded jaws and rely on flying to hunt and prey on mosquitoes, small insects, some of which can prey on dragonflies, butterflies and so on.
