CATDOLL : CATDOLL: Please tell me how to keep spiders?

Living habits

Spiders feed on insects, other spiders, and myriapods. Jumping spiders have excellent vision and can sneak up on their prey within 5 or 10 meters and pounce on it. Crab spiders wait for prey on flowers of similar color to themselves. Ground spiders, which live in the soil, build burrows lined with silk and have flaps that open at night to catch insects passing through the burrow. Funnel-web spiders weave a flat web that vibrates when insects fall into it; the spider itself lives in a silk tube with a narrow end that leads into plants or cracks in rocks. Most orb-shaped spiders use the least amount of silk to weave the largest web, which acts like an air filter to trap insects that are not able to fly well and do not see the fine silk. Although the web is complex, it can usually be woven within an hour, and is usually completed before dawn. If the web is damaged during hunting, a new web is woven. Why the spider itself does not get stuck in the web and how it cuts the extremely elastic silk when weaving the web are not fully understood. When weaving an orb web, the spider releases a thread that floats away with the wind. If the free end of the silk fails to stick to something, the spider pulls the silk back and eats it. If the silk sticks firmly to something (such as a branch), the spider passes over the silk bridge and reinforces it with silk. The spider fixes a thread in the center of the bridge, hangs down on a thread, and sticks to the ground or another branch. The spider returns to the center and pulls multiple radial threads radiating from the center of the web to the surrounding areas. Then, the spider crawls back to the center of the web and pulls temporary spiral silk from the inside to the outside with dry silk, with large spacing between each spiral. Then the spider crawls to the outermost part and places tighter insect-catching spiral silk with stickiness from the outside to the center of the web. While making the web, the spider eats the previously made non-sticky dry spiral silk. After the web is completed, some spiders pull a thread (signal silk) from the center of the web and crawl to the leaves in a corner of the web to hide. If an insect casts a net, it can hear the vibration of the signal silk and come to eat. Some spiders stay in the center of their webs with their heads down, waiting for prey. When prey is found, they wrap it in silk, bite it, and carry it back to the center of the web or to a hidden place to eat or store it. Butterflies and moths are large and easy to escape, so they bite first and then tie them up with silk. Some spiders build communal webs, such as the Gaboon social funnel-web spider (Agelena conso ciata), which builds a large web in which hundreds of spiders hunt together. Spiders may play an important role in controlling the population of certain insects. Several venomous spiders have neurotoxins that are toxic to humans. The process of weaving webs has aroused scientific interest and has been used to study drugs that affect the nervous system (the webs that spiders weave after taking drugs are different from normal).

Based on their lifestyle and predation methods, they can be roughly divided into two types: web-building spiders and wandering spiders.

The most important feature of web-building spiders is their web-building behavior. Spiders secrete mucus through the protrusions at the tip of the silk sac, and this mucus can condense into very fine silk when it comes into contact with air. The web made of silk is highly sticky and is the main means of predation for spiders. For insects stuck on the web, the spider will first inject a special liquid digestive enzyme into the prey. This digestive enzyme can make the insects comatose, convulse, and even die, and liquefy the body. After liquefaction, the spider eats it by sucking. Spiders are oviparous, and most male spiders will be swallowed by the female spider after mating with the female spider and become the female spider's food.

Wandering spiders do not weave webs, but instead wander around or camouflage themselves on the spot to hunt prey, such as the stilt spider, commonly known as (Chong Na) (Chong E) in Taiwan.

Some spiders can use their webs to make a balloon and float to other places with the wind.

Spiders are not considered food on the table for humans, and they are even afraid to stay away from them. Lu Xun once said, "The first person who ate crabs is very admirable. Who would dare to eat it if he was not a warrior? Some people eat crabs, and some people must have eaten spiders as well. But they are not delicious, so later generations stopped eating them" ("Two Thoughts on Spring"). But recently some areas, such as the Sukhumvit area in Cambodia, are selling spiders as a dish.

Spiders mainly prey on small insects. Wolf spiders near water can prey on small fish and shrimps, bird spiders can catch birds (it is said, but there is no exact documented record), and a 7.5 cm long spider in South America can even catch small rattlesnakes. Web-spinning spiders catch prey with their webs.

(1) Corpse Transformation Method:

When hunting, spiders first use the toxins in their fangs to paralyze their prey, then secrete digestive juices into the prey's body to dissolve the prey, and then slowly suck it up, eating it all up without leaving a single bit behind.

(ii) Homemade fresh-keeping bags:

Spiders are afraid of light and often weave webs in places with light and ventilation. In addition to being used to catch prey, spider silk can also be used as a fresh-keeping bag. Spiders use their webs to wrap up leftover food and save it for next time.

(III) Mysophobia:

Spiders have clearly separated the places for eating, sleeping and defecating. Domestic spiders usually use the side of the cage as a garbage station, where they urinate, defecate and throw food scraps.

(IV) Very good appetite:

Spiders have a strong sense of territory and should be kept alone. They only eat one or two meals a month and can go without food for up to two months. Their food mainly consists of insects such as crickets and grasshoppers. Just put a wet sponge in the cage to replenish its water, and you can keep it until it reaches adulthood (about seven years) without changing the cage.

Not all spiders are poisonous (spiders of the family Theridiidae are not poisonous)! And the toxicity varies. Usually, pet hairy spiders on the market are less toxic and will not attack people unless they are deliberately teased. Even if you are bitten, your life will not be in danger. It has strong adaptability and does not require careful care. Spiders are the easiest pets to keep.

Spider silk is expected to be used to make high-strength materials. Experts from the Institute of Genetic Biology of the Russian Academy of Sciences are actively studying the use of spider silk to make high-strength materials. There is a cluster of spinning organs behind the abdomen of spiders, which are connected to the silk glands in the body. The protein mucus secreted by the glands can condense into extremely strong spider silk in the air. According to the Russian newspaper "Moscow Komsomolskaya Gazeta", experts from the Institute of Genetic Biology of the Russian Academy of Sciences found that when conducting experiments on materials with a certain thickness woven from spider silk, the hardness of this material is 9 times higher than that of steel of the same thickness, and the elasticity is 2 times higher than that of other most elastic synthetic materials. Experts believe that after further processing of the above-mentioned spider silk materials, they can be used to make products such as light bulletproof vests, parachutes, weapons and equipment protection materials, wheel tires, plastic surgery tools and high-strength fishing nets.

Food feeding

Spiders are carnivorous and have a wide range of diets, but they mainly prey on insects. Sometimes they can prey on animals several times larger than themselves, such as the South American tarantula, which sometimes preys on small birds and mice. The mouth of a spider is only suitable for sucking liquid food. When catching prey, it first injects venom into the prey, anesthetizes or kills the prey, and then secretes digestive fluid, which is injected into the prey's body through the prey's wounds. It first digests the prey externally, and then absorbs it into the body after the prey's soft tissue is decomposed and liquefied, and then digested and absorbed into the body.

Since spiders are ferocious, all carnivorous, and have a habit of killing each other, it is easy to succeed when they are raised alone, but difficult to raise in groups. Also, because spiders have a variety of diets, are resistant to hunger, and have strong vitality, as long as the three basic conditions of food, water, and shelter are guaranteed, success can be achieved. In a gas lampshade, a 1 cm long wolf spider can catch 7 to 12 louse, leafhoppers, and flies every day. The wolf spider can withstand hunger for 34 to 112 days without water. The spider's strong hunger resistance is related to its large appetite. Generally, the higher the temperature, the worse the hunger resistance.

1. Single-cell feeding

(1) Hunting spiders: Since they do not weave webs, the breeding containers used can be smaller, such as glass bottles, tubes, lampshades, and culture dishes.

(2) Single spider rearing in a mosquito-catching glass tube. The mouth of the tube is a cork stopper with a small glass tube. The lower end of the small glass tube is plugged with a small cotton ball. Clean water or 10% honey solution (for raising young spiders) can be injected through the top of the small glass tube to provide water. The other end of the mosquito-catching glass tube is a round bottom that protrudes into the tube. There is a small hole in the center of the bottom, which is plugged with cotton to prevent the spider from escaping. This hole can also be used to put in live insects such as plant lice, leafhoppers, aphids, flies, or artificial feed such as egg yolk to provide food.

(3) Lampshade breeding: Suitable for medium-sized spiders that do not weave webs. Tie the top of the lampshade with gauze and make a small hole in the gauze. Install a glass tube for water and food. Place a white porcelain pot that is larger than the lampshade on top of the lampshade. Spread fertile soil in the pot and plant plants that are suitable for the living conditions of the spider. It can be used to raise adult spiders and young spiders.

(4) Wooden box breeding: Suitable for web-building spiders, such as garden spiders and octopus spiders. The height of the wooden box should be about 1 meter. The wooden board only needs to be smooth on the outside, and the inside can be rough to facilitate spider crawling. There is a valve at the bottom of each side of the box to facilitate operation inside the box. The top and four sides of the box are surrounded by nylon mesh to facilitate ventilation and light transmission. The box can be arranged to simulate natural living conditions, which is convenient for setting up webs, living and hunting. A water culture dish can be placed (use cotton balls to store water without drowning the spiders) and another dish containing artificial feed can be placed.

2. Group feeding

Larger wooden boxes can be designed to increase the number of spider species and spiders, and the layout inside the box should simulate the natural ecological conditions of spiders. There is also a breeding box with iron window screens as cage walls, which can be directly covered with straw, and a funnel-shaped insect collector is installed on the top of the cage. Lights are used to lure insects. The group breeding method is difficult to achieve ideal results and is still under exploration.

3. Artificial feed

There are many types of spiders, and their diet is varied. It is not easy to develop effective human feed. Here we introduce an artificial feed suitable for raising red claw spiders and wolf spiders. Crab spiders were fed with a mixed feed of 4 parts egg yolk and 1 part miscellaneous materials for 6 weeks, and no adverse effects were found. Spiders like to prey on fresh meat, which has a great control effect on flies and mosquitoes in the home.

If we really want to destroy them,

1. You can use a broom to destroy their webs;

2. You can use low-toxic lime water to spray the ground and corners, and then sweep it away after a few days;

3. If it is in the city, I won’t talk about it. If it is in the countryside, you can tie the straw into a bundle where spiders often appear, lure them to burrow in and live during the day, and then burn them in batches;

4. You can burn wormwood leaves, mosquito coils, etc. to repel them;

5. You can choose to spray trichlorodicofol, which is low-toxic to humans and animals.

In addition to maintaining a clean environment, do not go online;

You could try psychotherapy.

method:

Sit quietly, close your eyes, imagine a spider crawling towards you from the ground or somewhere, you start to get nervous, and then it crawls on you, think about what you will do, hold on, look at it, and then imagine yourself standing up and shaking your body or swinging your arms or using a book to get rid of it, pick it up with white paper etc. and throw it out the window. It is not poisonous (we are not in the rain forest) and is a beneficial insect, there is no need to kill it.

Open your eyes and think back, in fact, you can't get hurt, and you can't die, it's no big deal, if you really encounter it again, just avoid it, it's nothing;

You can practice it over and over again, even if it is a "drill"

I was also afraid of spiders when I was a kid, but I forgot about it later. Although I am no longer afraid of the black and gray ones like my brother's when I see them outside, I still dare not approach the ones with yellow and black stripes.

Don't be afraid of the little spiders, it's a good sign, don't kill them, release them

What I fear and hate most is spiders. I think you are scary.
