CATDOLL : CATDOLL: Raising spiders to catch insects (raising spiders and getting caught)

1. Is it better to raise a spider or a mantis?

Spiders like to make webs to catch small insects and flies. Spiders are only suitable for survival in the wild and are difficult to keep. If you keep spiders at home, they will not be able to catch small flies and will starve to death.

Mantises are also carnivorous insects, and they are only suitable for survival in the wild. If you keep a mantis at home, it will not be able to catch small insects and will starve to death. In short, spiders and mantises are not suitable for humans to keep.

2. What kind of spider is this? Can it weave a web? Will it bite people? Do you want to keep it at home to catch insects?

Spiders will definitely weave webs. If you don't touch them, they won't bite you, but they can catch insects.

Spiders choose to weave their webs when there is wind. They first spin silk continuously in a fixed place, and the silk will float in the wind. Then, the spider will use its feet to test the silk. If any silk cannot be pulled, it means that the other end of the silk has been fixed to an object. Then, it will use this silk as a basis and spin several main silks around to complete the main framework. Finally, it will begin to weave its web bit by bit.

After the web is made, the spider hides. If prey hits the web, the spider will judge the size of the prey by the intensity and frequency of the vibrations transmitted from the web. Then it will walk towards the prey, grab it, and continue to spit silk to wrap it up. At this time, the spider has injected a liquid called jujube digestive enzyme into the prey's body. This liquid will paralyze the nerves, make the prey comatose and die, and the prey's body will liquefy. Finally, the spider will "drink" the prey like drinking yogurt.

3. Is it efficient to keep a white-fronted spider at home to eat cockroaches?

The white-fronted stilt spider is a non-toxic spider. Even if it is bitten, it will not cause serious harm. It does not make webs. It mainly survives by preying on cockroaches, flies, moths and other insects. It can be considered a beneficial insect. It has a large appetite and can prey on multiple cockroaches continuously. If you let the white-fronted stilt spider live in your home, it will kill cockroaches naturally. The white-fronted stilt spider is easy to raise artificially. It not only eats cockroaches, flies, moths, but also eats small insects such as crickets. It has a good hunger tolerance and can be fed only once or twice a week. Of course, if conditions permit, it is better to feed it every day.

4. How do spiders catch insects?

Spiders are small animals that people often see in their daily lives. The big ones can be 10 cm long, and the small ones are only 1 mm. There are many species and they are widely distributed, but all spiders feed on small animals, mainly insects. They do not harm crops and are natural enemies of pests. Therefore, the proverb "If there are many spiders, everything will be happy" has been circulated among the people for a long time, and spiders are regarded as a sign of a good harvest. Spiders weave webs to catch insects, which is familiar to everyone. In fact, spiders are divided into two types: web-building type and hunting type. Hunting spiders, such as wolf spiders, do not weave webs. Although they do not weave webs, their hunting ability is not small. They have sharp eyes and quick movements. When they find their prey, they quietly crawl to the prey, take advantage of the prey's unpreparedness, suddenly jump up, catch the small insects with lightning speed, bite them with their chelicerae, and then excrete venom to poison them to death, and then eat them. If we observe the web-weaving spider carefully, we will find that the webs made by spiders can be divided into five types. The first type is the most common round web, which is also known as the gossip web. The web is on the same plane, and the spider silk is arranged radially from the center to the surroundings, and many horizontal silks are connected in the middle. The second type is called the funnel web, which is shaped like a funnel, and there is a silk tube next to it for the spider to enter and exit when moving on the web. The third type of web is triangular, called the triangle web. The fourth type is called the canopy web, which weaves silk into silk layers and arranges them on a plane. The other silks extend irregularly in all directions. The fifth type of web is irregularly extended in all directions, which is called the irregular web. No matter what kind of web, it is very effective in catching insects. Whenever a small insect hits the web and is stuck, the spider quickly crawls over to catch it. If the prey struggles on the web, the spider will first poison it with venom and then catch it. The spider's chelicerae are a pair of appendages at the front of the head and thorax. There are venom glands inside, and the venom secreted is very strong. Not to mention insects, some spiders can bite cows to death. Poisonous spiders are very poisonous. For example, the bird spider is 10 cm long, dark brown in color, covered with a layer of fluff, with long and powerful legs, good at jumping, and burrows in the soil. It comes out at night to catch insects and sometimes preys on birds on trees. The venom secreted by its venom gland is very toxic. According to experimental observations, a rabbit weighing 1 kg will die in just 4 minutes after being bitten. According to records in southern my country, when cattle are grazing on grasslands, they often touch the webs of these spiders, causing these spiders to jump out and bite the cattle's mouths. The slowest one takes half a day, and the fastest one takes 10 minutes, which can kill the cattle. In addition, stinging red spiders, burrowing wolf spiders, and red-spotted black spiders nicknamed black widows are all poisonous spiders distributed in my country. They can often bite people and animals, and even poison them to death after biting. Therefore, if you are bitten by a poisonous spider in the wild, you should seek medical treatment in time to avoid serious consequences. But generally speaking, field spiders are not only harmless, but are friends of humans. Using spiders to control pests can save a lot of pesticides and manpower and material resources, and can prevent pollution and protect the ecological environment.

5. What are the precautions and taboos for novices in raising spiders?

1. You need to choose a suitable breeding box and place a shelter (generally bark, but there are also shelters made of other materials). Arboreal spiders need a relatively high box, while terrestrial spiders can use a flat box. The box should not be too big or too small, but a box of moderate size. Spiders need shelter to feel safe, especially arboreal species such as the gorgeous rainforest and pink toes. Therefore, it is also very important to arrange shelters.

2. Control the temperature. Pet spiders, especially tarantulas, are mostly tropical species. Therefore, they have high temperature requirements. Generally speaking, they will eat less if the temperature is below 20 degrees, and their lives will be in danger if the temperature is below 10 degrees. Not to mention the minus dozens of degrees in the Northeast, there is no hope. Therefore, a heating pad is essential for raising pet spiders. Of course, it would be better to use a constant temperature box if conditions permit.

04. Control the humidity. This is also because they come from the tropics. Especially for pet spiders that come from rainforest climates. Generally speaking, they have higher requirements for air humidity. But the air humidity cannot be too high. Too low air humidity will cause juvenile spiders to dehydrate due to dryness, and adult or sub-adult spiders will not be able to complete molting. Too high air humidity will cause your pet spider to suffer from "soft feet syndrome". So it is necessary to buy a hygrometer.

6. What pests do spiders catch?

It will catch pests around its web, such as mosquitoes, flies, moths, butterflies and other pests, and sometimes eat bees or dragonflies that hit the web.

Relatively speaking, spiders can be said to be beneficial insects in our lives. They are of many species and have strong adaptability. They feed on small animals, mainly mosquitoes, flies, moths, etc.

Spiders are both beneficial and harmful to humans, but in terms of their contribution, they are mainly beneficial insects. For example, spiders in farmland mostly prey on crop pests. At the same time, many traditional Chinese medicines have records of using spiders as medicine, so it is of great significance to protect and utilize spiders.

7. How do spiders catch insects?

Jumping spiders (also called "fly tigers") can see and identify their prey at a distance of 30 times their body length, then quietly approach and finally catch the insect by jumping and lunging.
