Every time it's summer,Mosquitoes will always buzz and appear in your ears on time.
You fight, it flies, you chase, it escapes, no matter what means you use, mosquitoes are the same as Xiaoqiang who can't be killed, always inadvertently in youGive you a tickling little red envelope.
You hate it to the core, but you can't do anything about it, and eventually you give up struggling.
But in nature, there is an insect called the mosquito nemesis, which can eat 3,000 mosquitoes a year, and no mosquito can escape safely under its hands.
But that's the kind of beneficial wormBut in recent years, it has been served to the table by humansThe market is in short supply for this, and the highest time is 80 yuan a catty.
The hot demand led to its gradual decrease in numberSo what kind of insect is this?
This insect usually lives in rice paddies or ponds in the south, and its body is usually dark brownPossesses a pair of large watery eyes and six slender **.
Its scientific name is the water beggar, and some people call it "water beggar", which sounds very weak.
But the water fly in the water is the exact opposite of its weak nameIt is known as the insect monster of the underwater worldAs long as it is not much larger than the water fly, it has the potential to become its prey.
And the reason why the water fly is strong,The reason for this is that it is comparable to the predation method of an Assassin.
It preys on itwill first disguise himself,In order to allow the prey to let down its guard, and different species of water bugs have their own unique skills.
Like a giant fly, it lurks in the mud at the bottom of the water and waits for an opportunityThe blue-tailed flyfly, on the other hand, is the opposite, because of its emerald green appearanceTherefore, it will choose to lurk among the aquatic plants to disguise itself.
The water fly's predation method is very brutalThe main hit is fast and accurate.
Underneath its head, there is a pair of extremely special pincers, which in normal times would shrink in front of it and remain motionless, when viewed from the frontLike a killer with a mask of hidden identity, his two big slippery eyes reveal ruthlessness.
When hunting, the water fly will remain motionless in the waterQuietly wait for the prey to pass by itselfAt this time, the fluctuation of the water flow changes,It will be caught by the keen sensory devices on the feet of the water fly.
When the time is right, the water fly will use the big pincers in its hand to give the prey a loving intimate hug in a lightning speedQuickly bite the prey and then quickly retract back to the mouth.
The prey may not have reacted before they see a pair of strong jaws devouring their body, and like all who see the killer's face, they will eventually die.
And the water fly's favorite food is mosquitoesIn particular, the larvae of mosquitoes are the favorite of water flies, and each water fly can eat about 3,000 mosquitoes or babes a year.
Just imagine, when the pink and tender cub swims hard on the surface of the water, the water bug that finds its prey doesn't even need to be camouflaged, and only swims to the side of the cub with a big square faceThen a small insect swallowed itI don't know how enjoyable it is.
Some people will say that the water fly is so powerful, doesn't it have any natural predators?Big fish and birds use the water fly as food, but it is not easy for them to catch the water fly.
The reason lies in the body of the water flyIt has its own unique "turbocharging" system.
Most of the water bugs have large or small hole-like structures at the end of the abdomen, and they will use these small holes when the water fly is in dangerWater is quickly inhaled into the body and then quickly sprayed out.
The strong propulsion force allows the water fly to quickly dodge the opponent's attack, so that it can retain a piece of life for itself and make a comeback in the future.
But such a water overlord-level player with very strong combat power and excellent life-saving ability has gradually decreased in recent years.
It is true that the water fly is a hegemon in the waterBut for human beings, it is still too small.
In some places, insects are often used as a special delicacy, and unfortunately, peopleThe water fly is one of the insects that can be eaten by humans.
Because it is rich in protein, whether it is fried or made into skewers, it can still give off an attractive aroma after being artificially processedNot only is it edible, but it also seems to taste pretty good.
In the past, when the conditions were more difficult, the water fly would become a rare delicacy on the dinner table, and many people still flock to it.
Experienced farmers often need only an hour or two to catch a small half-bucket of water bugs, but this is not enough for the market.
Maybe there are really people who love to eat, or maybe some people want to try it, which leads to the water fly is very popular in the marketUsually it can be sold for about 30 to 50 yuan, and at the most expensive time, it can even be sold for 80 yuan a catty, and even beef is not so expensive.
Some people say it's a pest, eat it because it deserves it, while others say it's a beneficial insect and we need to protect it.
Is the water fly good or bad?This requires us to see where it grows.
As mentioned earlier, although the water fly likes to eat mosquito larvae, it does not refuse to comeAs long as it is smaller or similar than its fish fry and shrimp fry, etc., all of them will become its belly food.
Therefore, if it appears in the pond where the seedlings have just been stocked, it will cause a decrease in the number of fish fry or shrimp fry, which will bring economic losses to the farmers, then it is a pest in the eyes of people.
But if the water fly appears in the farmland where rice is grown, it will strike hard at the pests that harm the riceIn order to increase the yield of rice, it is an out-and-out beneficial insect.
And we need to know that the current appearance of the water fly is not its final formIt's actually the dragonfly's juvenile years.
Different species of water fly take different time to grow, the short one may only take two or three months, the common species is longer, about one to three years, and some are more extremeIt takes eight years to become an adult.
After a dozen molts, the water fly will eventually shed its shell and become a flying dragonfly.
With its super compound eyes and dexterous flight methods, dragonflies have become the number one natural enemy of mosquitoes, and any annoying mosquito can't escape the hunt of dragonflies.
Unfortunately, as the number of water flies decreases, so does the number of dragonflies.
In the ecological cycle, each species has its own unique meaning of existence, and we must protect the ecological cycle, so as to create a better tomorrow.
