How do spiders catch flying insects 5, how do spiders catch flying insects

Different spiders are different, but they generally build a web and wait for the rabbit. After the prey reaches the net, some inject venom into the prey to paralyze the prey. Then tie it up with a net and enjoy it later. Of course, there are some spiders that do not form webs, such as tiger flies

Use spider webs to stick to the flying insects, wait for the flying insects to surf the Internet, inject venom into the prey, and enjoy them slowly.

Spiders don't catch things, it's flying insects that fly to spider webs and get caught.

Get the net right. I'm waiting for the flying insects to get on it.

Catching a spider is a four-step process:

The tools you need are: jelly boxes, small jars, tweezers, and insect nets.

1. Before catching spiders, you should first judge whether the spiders are poisonous, and do not catch them casually to cause poisoning.

2. If it is a relatively small spider, you can use leftover jelly boxes and small jars to catch it. Buckle directly on top of the spider.

3. If it is a harmless spider, you can use tweezers, pinch the spider and put it in a container, and be sure to pay attention to good ventilation.

4. If it is a relatively large spider, you can use an insect trap net to catch it.

How spiders hunt:

Spider predation is relying on the web to catch the prey, the spider weaves the web and returns to the center of the web to wait for the prey, the spider silk has a strong adhesion, the prey struggles violently after colliding, the spider in the center can sense, the spider will inject toxic digestive enzymes after catching the prey, first poison the prey, and then drag the prey to the center of the web.

Catching a spider is not an easy task, and here's how.

1. The location can generally be seen in the field, grass or some branches, but most of them are active on the ground, so be sure to observe carefully.

2. For the spiders on the branches, such as the big-bellied garden spider, for this kind of simple use that only needs to use a web, the green web in the picture, there are small web-catching insects are better.

3. Leaf curling spiders need to be carefully driven away with tweezers, and then immediately use another tweezers to clamp its opening, and then put it into the test tube prepared by yourself. In the case of a tarantula, you can numb it with alcohol and then clip it into a test tube with forceps.

4. If it is a tarantula, you can use alcohol to numb it, and then use tweezers to clamp it into the test tube.

5. There is also a kind of living in the crypt, once there is movement, it will be caught immediately, so at this time you need to use a shovel, first open the cave and grab it immediately, this hand should be fast, or use the bait to seduce out and catch.

How do spiders hunt?

Spiders use the least amount of silk to weave the largest web, which acts like an air filter to trap insects that do not see filaments and are not very flying. If an insect throws a net, it can hear the signal and feed through the vibration of the signal wire.

After capturing the prey, the venom secreted by the venom gland in the chelicera is injected into the captured prey to kill it, and the digestive enzymes secreted by the midgut are infused into the tissue of the captured object shredded by the chelicera, which is quickly broken down into juice and then sucked into the digestive tract.

The spider is very serious, and every silk it spits out must be tough enough that it can follow a spider silk, vertically, and move straight, and the web must not only bear its own weight, but also the weight of many prey. It is a matter of the safety of one's own life and the needs of the harvest, and there is no room for sloppiness.

Summary. Hello, because insects can't recognize the existence of spider webs, although insects have a lot of eyeballs, and they react faster than us humans, looking at this fast, they can't recognize the existence of spider webs. So there are times when a fast-moving flight can cause insects to hit a spider's web.

So, the insect will fall into the spider's web and become the spider's meal.

Hello, I have seen your question and am sorting out the answer, please wait for a while Hello because insects are unable to recognize the existence of spider webs, although insects have a lot of eyeballs, and they react faster than us humans, looking at this kind of speed, they also make it impossible for them to recognize the existence of spider webs. So there are times when a fast-moving flight can cause insects to hit a spider's web. So, the insect will fall into the spider's web and become the spider's meal.

And the rules of nature affect every living thing, including us humans, and we humans cannot interfere with it. So the evolution of species is very tortuous and adaptive, spiders know insects, they can't recognize some transparent, and the spider webs they make are colorless and transparent.

1. Catch it with a cautious hand, if there are not many spiders and you haven't seen it in a hidden location such as a cabinet, you can grab it directly. Spiders are beneficial insects that can help you eat other insects in your home, try not to kill them.

2. If you are afraid of spiders and dare not catch them with your hands, you can use an electric mosquito swatter, and electric insects are also a very useful tool.

3. If the number of spiders is too large, you can spray with insecticides, or you can spray more in the room, close the window and lock the door for half an hour to enter, pay attention to immediate ventilation, after the spider is eliminated, it is recommended to clean the room frequently, take a feather duster to remove the dust on the wall, and put some mothballs in the cabinet.

4. Keep the surface clean at home, and vacuum regularly, if the home is not clean, or there are food residues such as bread crumbs, it will attract pests to enter and also attract those spiders who feed on pests. A clean environment will leave them with nowhere to hide.
