What are the wonders of spider egg pouches?

Before laying eggs, females weave a web similar to the size of their abdomen. The eggs are then laid on a mesh, and another mesh is woven to cover it, and the edges are closed with silk to make a spherical egg bag. The spider's egg pouch is very chic and waterproof, even in the face of wind and rain.

The inside of the egg pouch is also very special, not at all like the texture of the appearance, but like velvet.

It is the same soft, and it has the effect of keeping warm from the cold. The spider's egg pouch is very chic, looking like a peach pit from a distance.

The top is small and the bottom is large, and it is like an upside-down balloon hanging on the wall. Although the spider's silk is also white, the egg bag does not resemble a silkworm cocoon at all.

It is made of layers of white silk wound with a sheepskin texture and tiny folds, which looks very strong.

The spider's egg pouch has several magical features:

1.Unique structure: The spider's egg pouch has a unique shape, which looks like a peach pit from a distance, small at the top and large at the bottom, and like an upside-down balloon hanging on the wall.

The material of the egg bag is very special, although it is also white, but unlike the cocoon, it is not made of layers of white silk, but more like a sheepskin texture, covered with fine folds.

2.Strong protection: The spider's egg bag has a waterproof function, which can protect the spider eggs inside the egg bag from being affected even in rainy days. In addition, the material of the inner wall of the egg bag has the effect of keeping warm and cold, providing a comfortable growth environment for newborn spiders.

3.Individual recognition: Each spider's egg pouch has its own unique texture and structure, which helps the mother spider to identify her own egg pouch and young spiders to some extent.

Overall, the spider's egg pouch is a well-crafted safe nursery for the mother spider, with a unique structure and function that provides all-round protection for the newborn spider.

I think it's a spider's silk sac, which should have liquid proteins in it, and when it comes out, it solidifies into silk when you see air.

That's the spider's egg, and it's breeding its own offspring.

Probably not, spiders don't lay eggs in the middle of their webs, just like people don't give birth in fishing nets, there are spiders that hunt and eat, spiders generally lay eggs in their nests, and what you see may just be the old web lines of spiders "**".

Possibly. Spider eggs are transparent and may have a white or yellow tinge.

This one is**.

This is the egg of the Black Widow spider, and the eggs of the other spiders may be smaller, but they should be about the same. That large web is called an egg bag, probably to protect the spider eggs, so let's get rid of it as soon as possible.

After the spider lays eggs, he usually runs on his back.

A round white cloth bag-like thing, when opened, there are many things the size of 1 3 millet grains inside.

I have two yellow-white spider eggs in my house, you say it's different from yours?

Some spiders have egg bags, and some spiders lay eggs on their bodies.

The spider likes to run around carrying its eggs on its back!!

Before the female spider lays eggs, it is made of silk"Puerperium"。Spawn on top of it, which is then covered with silk. And the egg bag is braided into a fixed form.

A female spider generally lays only one egg bag, but also lays multiple egg bags, such as 5 6 garden spiders, 13 red spotted spiders, and the number of eggs laid by a female spider can range from a few to hundreds, such as 60 720 red spotted spiders, and 1000 species of garden spiders.

The hatchlings hatched from the egg shell remain in the egg bag and must undergo one molt in the egg bag before leaving the egg bag. Because tarantulas not only hunt with egg bags, but also have the habit of carrying young when the young spiders hatch, they are called swaddling spiders. Female spiders die after being braided into egg bags, some die after the young spiders are separated from the egg bags, and some are bitten to death by their own hatchlings for food.

Before the spider reaches maturity, as it grows, it must go through many molts, and the number of molts and the interval between them are very inconsistent, generally speaking, small spiders molt 4 5 times in their lifetime; medium-sized spiders about 7 to 8 times; Large spiders are about 11 13 times, such as the male spider of the red spotted venomous spider molts 5 times and the female spider 7 times.

Natural enemies of spiders.

Spiders have many natural predators. Toads, frogs, lizards, centipedes, bees, and birds all prey on spiders, some parasitic wasps parasitize in spider eggs, some parasitic flies develop larvae in spider egg pouches, and small-headed gnatfly insects almost all parasitize into spiders in the form of larvae.

Spiders often use a variety of methods to ward off enemies, such as ventilating venom, stealth, camouflage, mimicry, protective color, vibration, and so on. When you can't escape, and your appendage is caught by the enemy, simply cut off your appendage and walk away, anyway, the self-cut step will regenerate when molting.

Benefits of spiders.

Spiders are both beneficial and harmful to humans, but in terms of their contributions, they are primarily beneficial insects. For example, in farmland, spiders prey mostly on pests of crops. At the same time, in many traditional Chinese medicines, there are records of using spiders in medicine, so it is of great significance to protect and use spiders.

In particular, the protection of rice field spiders has three major benefits: first, it effectively stabilizes the balance of biological populations; the second is to reduce the residual toxicity of chemical pesticides in rice and ensure the safety of humans and animals; Third, the production cost is reduced, and the production and income can be increased. Therefore, in the prevention and control of crop diseases and pests, we advocate the use of high-efficiency and low-toxicity pesticides, carry out biological control, and protect natural enemies.

The spider is an arthropod, and it has eight legs and a silk spin at the back of its abdomen. Web-forming predation is a unique skill of spiders. Spiders in knotted webs.

Due to different habits, the shape of the net is also different, including canopy net, funnel net, irregular net and basin net. The most delicate thing about the towel is the common wheel round net, which is radial, like the ancient Bagua Array.

Spiders are also unique in that they don't gobble up their catches right away, but use their teeth first.

The body of the stabbing prey is injected with venom to anesthetize the prey and then slowly sucked it.

The spider usually spits out white silk when it weaves its webs, but when it weaves the egg sack for its children, it spits out different colors of silk: the spider first uses filament to connect the branches and pincer leaves, and after the shelf is set up, it gradually weaves a pocket of 1 centimeter on the left, and then uses many strips of silk to connect the pocket to the nearby silk. When spawning, the eggs fall into the open pouch opening.

The volume of the bag also seems to have been precisely calculated in advance, and the eggs laid are exactly enough to fill the mouth of the bag. Then the spider weaves a felt cover at the mouth of the bag. Then the second layer is weaved, and at this point, the silk spit out by the silk sac becomes a fine soft reddish-brown silk and is no longer white.

The silk gushes out like a cloud, wrapping the egg sack of **, and the spider will use its hind legs to pat them into a loose layer of cotton tire, and then the spider spits out white silk again, this time to weave a thick outer layer. On the edge of the neck of the bag, it is carefully woven. After weaving the surrounding vertical layer, the spider spits out a dark brown to black silk and makes a beautiful ribbon web on the outside of the pouch

When it was done, the mother spider left the bag.

The mother weaves a nursery bag in August to lay her eggs, and in the winter, in June, just as the eggs hatch, the hatching bag opens automatically, and the spiders can crawl out.

After the spider crawls out of the egg pouch. And when a gust of wind blew, the silk broke, and the severed silk carried the spiders to the ground one by one. The broken silk became a safety rope, which is very ingenious:

During the incubation process, the spider's egg bag is composed of different colored silks, which shows that he is a chemist and textile fiber manufacturer, and it can be seen that the nursery bag bursts and opens when it is exposed to sunlight and the spider lands safely on the principle of safety rope.

Carnivorous arthropods, 8-legged, not insects, molt and mostly form webs.

The burden of Mother Spider is really not light! It has to take care of three egg bags at the same time every day.

The spider's egg pouch is very chic, looking like a peach pit from a distance, small at the top and large at the bottom, and like an upside-down balloon hanging on the wall. Although the spider's silk is also white, the egg pouch is not at all made of layers of white silk like a silkworm cocoon, but has a sheepskin texture and is covered with tiny folds, which looks very strong.

The spider's egg pouch is waterproof, even if it is exposed to wind and rain. The inner wall of the egg bag is fluffy and soft, like velvet, which plays a role in keeping warm from the cold.

The little spider is born in such a warm and comfortable egg bag, and it is really much luckier than other small insects.

In the next few days, Mother Spider's task will be even more onerous. Because there is a little spider in an egg bag that can't wait to come to the outside world. The little spider bit the egg bag and poured out at once, and there were more than a hundred of them in total.

The little spiders that have just come out of the egg bag do not dare to leave their mother, so they can only gather near the egg bag.

It's not as safe outside as it is in the egg bag, not only are there geckos that prey on spiders, but also the capricious weather, especially in the last few days, when the sun is still sunny and clear, and in the blink of an eye, the weak spiders can't resist these for a while.

The mother spider gets busy, weaving a protective web around the broken egg sack to keep the spiders out and keep the intruders out.

The mother spider went to the top of the egg bag again, and spat some messy silk in the corner of the wall, and I was wondering when a leaf of a maple poplar tree fell down, just in time to be stopped by the messy spider silk, and at right angles to the wall, so this leaf naturally became an awning above the egg bag.

In this way, the newly hatched spider can not only cool under the awning, but also avoid getting wet in the rain.

You are ignorant ...

It unpacked it on its own, indicating that it thought it could breathe. It must be that your humidity and temperature are not right, and it is normal that after it lays eggs, experienced people will be forced to take it out. Control the temperature and humidity yourself, and unpack the yellow egg after 20 days, if you take a closer look, it is a spider in a ball!!

It should be your environment that causes her to be insecure and unwilling to protect her eggs, but to eat the egg bag, just like a fox who gives birth to a cub and is disturbed and eats her child.
