Flies react so quickly, so why do they still fall into spider webs?

Flies and spiders are some of nature's most amazing insects, and they both have their own very unique skills. Flies are very ancient creatures on Earth, and flies have been on Earth for hundreds of millions of years. After hundreds of millions of years of continuous evolution, the eyes of flies have evolved into a grid-like compound eye, which is composed of tens of thousands of single eyes, and the field of view of the compound eye can reach 240 degrees, which can effectively calculate the orientation and distance between itself and the object observed, so as to make a faster judgment and response to natural enemies.

But compound eyes also have their disadvantages, although flies observe the direction and distance of objects through tens of thousands of compound eyes, but the resolution of one eye is very low, so they can't really see objects clearly, that is to say, flies are veritable ultra-high myopia. There are many natural predators of flies in nature, but these animals are very slow, such as chameleons, spiders, geckos, etc.

Spiders are very important creatures in terrestrial ecosystems, and they are natural enemies of many pests, including flies. Spiders catch insects by means of very special, most of the spiders on the earth belong to ambush predatory organisms, they will secrete a special protein substance from the textile in the abdomen, these substances will quickly condense when they encounter air, spiders are constantly crawling in the process of constantly releasing spider silk, and finally form a spider web, although the spider web will condense in the air, but because of the different types of amino acids in the spider web, some amino acids will not coagulate, This makes the web very sticky and stretchable.

The eyes of many insects in nature are compound eye structures, which make the vision of insects with compound eye structures very poor, they cannot see the objects in front of them clearly in the process of flying, and can only change their flight direction by feeling the vibration of the air. However, the spider web minimizes the vibration of the air in the process of weaving, so the compound eye insect will fall into the spider web and become the spider's meal.

This is because the cobwebs are too thin for the flies to see clearly, and although they react quickly, they don't have time to react when they fly closer.

Because flies have poor eyesight, it is not easy to find cobwebs, and they will always be stuck by cobwebs, and no matter how fast they react, they can't avoid it.

The first condition must be summer, only hot days in summer.

Flies must fly on pine trees, and only pine trees have pine resin.

It must happen in a pine forest, and it must fall, on an old pine tree, because there are many ruler trees, there will be perennial old trees, and only old trees will drop big drops of pine resin.

It doesn't work by coincidence, it must be the spider that just pounced on the fly, and the pine resin dripped down.

Strange Amber (excerpt).

In that transparent piece of amber, two small things were still lying well. We can see every hair on them. You can also vaguely imagine how they struggled in the sticky pine resin, as several black rings appeared around its legs.

From that piece of amber, we can speculate on the details of the story that took place 10,000 years ago, and we can know that in ancient times, there were flies and spiders in the world.

Summary. Scorpions may feel frightened and helpless when eaten by spiders.

Scorpions may feel frightened and helpless when eaten by spiders.

Can you add, I don't quite understand it.

The feeling of a scorpion being eaten by a spider can be fear and helplessness. Scorpions are insects that are eaten by spiders, and their body structure is larger than that of spiders, but they are much less powerful than spiders. Therefore, when scorpions are eaten by spiders, they may feel fear and unaltered erection.

The reason why scorpions are eaten by spiders is that scorpions have a larger body structure than spiders, but they have much less strength than spiders. Spiders have a powerful venom that can make the scorpion's body weak, making it easier for the spider to eat them. The best way to solve the problem of scorpions being eaten by spiders is to prevent it.

Some natural enemies of the scorpion, such as praying mantises, can be placed in the home and let them prey on the spiders, thus reducing the number of spiders and thus reducing the likelihood of the scorpion being eaten by the spiders. In addition, you can also place some prey of scorpions, such as ants, in your home to make it easier for them to find food, thus reducing the likelihood that they will be eaten by spiders. Personal Tips:

The best way to prevent scorpions from being eaten by spiders is to prevent them, and you can place some natural enemies and prey of scorpions at home, so as to reduce the possibility of scorpions being eaten by spiders. In addition, you can also clean up the clutter in your home regularly to reduce the number of spiders.

a Circling; b Intelligent; c. Flap wings; d Dance. Similar, similar, different b Mosquitoes and flies both win first (succeed) and then lose, experience, end are similar, but the reasons for death are different. Mosquitoes die of triumphant victory, flies die of applying local experience everywhere.

c The use of "smart" to modify the central phrase contains a satire of flies, indicating that dogmatic intelligence is really stupid.
