Before said that the dipteran insect fly family on behalf of the fly rampant flies have brought a lot of trouble to people and some of them have also endangered human health, it is the mischief of these flies that makes me think that the insects of the entire fly family are bad pests, but today we are going to talk about this, it comes from the diptera flies, its name is called the aphid fly, and its appearance is to tell people what is called silt without staining.
Flies are notorious, the only use is to act as a decomposer in nature, a good even if not worth tens of millions of bad, so people hate them from the bottom of their hearts, and aphids are different, although it belongs to the fly family, it is indeed a full beneficial insect, can be described as a million pest compatriots stand out, bent on being a beneficial insect.
<h1>Beneficial insects fight from an early age</h1>
Aphid-eating larvae are beneficial insects, although their larvae are somewhat similar to maggots, after all, they are all fly creatures, but there is still a difference, maggots are white soft and sticky, so people see that there is a disgusting feeling, aphid-eating fly larvae are only similar in appearance to maggots, but it has a color, so it is not so disgusting.
And say that the larvae of the aphid fly, they are several species, some feed on saprophytic organisms, mainly eat rotten plants and animals, while others are mainly insectivorous, mainly feeding on aphids, wood slotworms and other pests that suck plants, so their main food source is these aphids that destroy plants and crops, so when they grow up, they are called aphids. However, because aphid-eating fly larvae often squirm on plants and their color will make people mistakenly think that they are pests, so there are often uninformed people who mistakenly injure the larvae of aphid-eating flies, but fortunately, when they grow up, everyone will not hurt them by mistake.
<h1>Cloak yourself in the clothes of beneficial insects</h1>
After a short period of independent killing and growth, the larvae of the aphid fly transform into a pupae, and after a period of time, they break out of the pupa and become an adult aphid-eating fly. It was said earlier that when they grow up, people will not mistake them for pests, and you know why, according to the reason, the appearance of flies is not a good thing at first glance.
With this doubt, let's take a look at the way the aphid fly grows up, if you don't look seriously, I even think this is a bee, the bee is recognized as a beneficial insect, it pollinates, makes honey, since ancient times, the story about the bee and the poetry and song of praise honey powder are not in the minority, the smart aphid fly may know that the bee is so cute, so it abandons the traditional fly family of appearance characteristics but the shape of the mimetic bee is covered with beneficial insects.
But in fact, this is also the last resort of the aphid fly, it does not have the arrogance of the fly, it does not eat feces and does not eat carrion, and their main food source in adulthood is also pollen. If it grows according to the appearance of flies, then there will be countless natural enemies in the wild, then it will not be able to survive, so it can only imitate the appearance of bees in order to deceive enemies and escape enemies, which is also known as Bayworth mimicry.
After successful mimetic bees, aphid-eating flies can freely and freely do a beneficial insect flying in the flowers and take on the same pollination work as bees, while other insects do not dare to easily offend when they see them and think that they are members of the army of bees that are not easy to provoke. Aphid-eating flies not only have the appearance of bees in appearance, but also have some advantages and advantages of flies, flies have developed compound eyes, fast reaction speed, fast flight speed, and extremely flexible steering, aphid-eating flies are very clever to inherit these advantages, really "take its essence, discard its dross".
<h1>Better body</h1>
Can grow like a bee and bees have the same hovering skills in the air, and can fly and turn quickly like a fly, and can also find out whether there is danger around them in time, and the aphid fly has gathered the advantages of flies and bees on its own. Friends who have carefully observed the flight of bees should all know that in the process of flying, the body will have a slight left and right shaking, as if the aircraft has just taken off and encountered a storm during flight to produce shaking, when sitting on the plane, shaking left and right will make people feel uncomfortable and will also affect the overall flight, the shaking of the bee flight will definitely affect itself; the fly-eating fly is different, it is like a smooth flight of the aircraft, fast and safe, this is because the aphid fly belongs to the order Diptera, the hindwings of the biptera degenerate into a balance stick, It is this balance bar that gives the aphid fly a smoother flight. With powerful flying machines, aphid-eating flies can hover at a certain point in the air for a long time and then suddenly move elsewhere, and the bees cannot perform such precise control.
Look at the eyes of the aphid-eating fly, the typical fly eyes, the difference is that the male eye is synygotic, and the female eye is detached. The huge compound eyes allow them to reach a 360-degree angle of view without dead angles.
The compound eye of the housefly is composed of 4000 small eyes, the structure of the small eye is very exquisite, it has a light collection device like a convex lens, called a cornoscope, that is, a hexagonal convex mirror on the surface of the small eye, with a conical crystal connected below, and the optic nerve is connected under these concentrators. The nerve senses the light points passed into the light collector and feels the stimulation of light, and then causes the "image of the point", and the image interaction of many small eyes forms a "mosaic image".
After having these excellent characteristics, the aphid fly also inherits the rapid response of the fly, we all know that when harassed by flies and mosquitoes, mosquitoes account for the majority compared to the two being slapped to death by people with their bare hands, this is the cunning of the fly, its nervous system is complex, the reaction speed is very fast, and the best escape route will be calculated in the moment of danger, so it is almost impossible to catch the fly with bare hands. The aphid-eating fly response follows the fly family very well, so it is probably not so simple for people to catch aphid-eating flies.
It was the presence of the aphid-eating fly that made me change my view of the fly family, which is not only not as annoying as flies, but also exists in the world as a beneficial insect, which is really a good insect that comes out of the mud and is not stained.
