The following are common spider species:
1. Bird-catching spiders: the whole body is brown, the individual is extra-large, generally about 7 cm long, some can reach 10 cm long, produced in Guangxi, Yunnan, Vietnam, Myanmar and other countries in China.
2. Chinese tarantula: dense black, white and yellow fine hairs all over the body, ctophorax and back brown, ** with a yellow-brown longitudinal spot. It is produced in Shaanxi, Shandong, Henan and other provinces.
3. Rod-roused bride spider: the spider is 3 5 cm long, the back of the cephalothorax is black-brown, the chelicerae are black, the tentacles are yellow, and each female spider reproduces 800 900 young spiders per year.
4. White-fronted Cancer Spider: The body of the spider is wide and short, flattened, the feet can stretch left and right, the body is large, it is one of the common spiders in the room, and every 800 1000 spiders can produce 1 gram of poison. The spider is mainly distributed in Shaanxi, Shandong, Sichuan, Jiangxi, Guizhou, Yunnan and other provinces and regions.

1 Professionally speaking, there are many species of spiders, nearly 4,000 genera and more than 40,000 species of spiders.
2 In the eyes of the general human being, spiders can be divided into web-forming spiders and non-web-forming spiders.
3 For those who like to keep spiders, spiders are divided into bird-catchers and non-bird-catchers.
4 For those who are afraid of spiders, spiders are divided into poisonous and non-venomous spiders.
5 That's probably it, I want to ask what spiders can be described in pictures or texts.

1. The round web, also known as the Bagua Array, is a regular spiral structure with a skeleton network, and generally large outdoor spiders (garden spiders, etc.) often form this kind of web.
Rotary screen. 2.The irregular flaky webs, which look disorganized at first glance, are actually a grid area within a plane, but the grids are of different shapes and sizes, such as ghost spiders.
A cluttered and irregular web.
3.The dish webs are also irregularly distributed, but the middle will be significantly lower than the surroundings, forming the shape of a dish, such as the outdoor pastoral spider.
dish nets. 4.The funnel web, surrounded by an irregular structure, is only denser, and has a tubular structure for escape, looking down from above, as if there is a hole, such as a labyrinth funnel spider.
Funnel web. 5.Irregular stereo nets.
Also known as the suspension bridge web, on the basis of the irregular sheet web, there are some more three-dimensional support wires, that is, three-dimensional webs, Australian black widow spiders are best at knotting this kind of web, if the ghost spider is placed in a small space with a certain height, it will also be forced to knot three-dimensional webs.
6.Radial stereoscopic nets.
It is also an irregular structure, but it has a distinct three-dimensional structure and is radial.
7.Curtain net. It is also called the dome net, which is about the same as the funnel net, and the irregular structure is like a tent.
8.Wheel netting.
It is also regular like a rotary net, but does not have a spiral structure.
Wheel mesh and radial three-dimensional net, the farther is the wheel net.

There are many species of spiders, and there are nearly 40,000 species of spiders in nature. These spiders can be broadly divided into three types: hunting spiders, web-building spiders and cave spiders.
The first type will go around foraging for food.
The second type is to wait for the rabbit after the net is built.
The third category: cave spiders. They like to hide in sand piles or burrows, and build nets at the mouth of the holes, which are not sticky and are purely used to sense the size of their prey and prey on them.
Habits of spiders:
1. Feeding habits: Spiders mostly feed on insects, other spiders, and myriapods, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them.
2. Lifestyle: Spiders are divided into indefinite and sedentary types, all of the squamolars of the family of indefinite, and most of them are mainly tarantulas. Sedentary:
Some build nets, some dig holes, and some build nests as fixed dwellings. Such as wall money, stone-like spiders, etc. Spiders seem to be polite, and those who live independently keep a certain distance from each other and do not invade each other.
It heralds a rebirth and a new level.
Spider webs are woven from the silk spun of some species of spiders, which are used to catch insects, small vertebrates, etc. for food, or to build nests for living. Spiders can sense the vibrations of their prey when they collide or become trapped in a spider's web; After finishing their webs, spiders wait on or near the web for their prey to fall into the trap. >>>More
Scientists have found that spiders generally have 6-8 textile webs at the end of their abdomen, and each textile has hundreds of spouts - the silk is discharged through the spouts. Spiders have glands with different functions corresponding to each spinn, and each gland produces a different raw material of silk thread, thus weaving both sticky and non-sticky silk threads. Scientists have found that the radial skeletal filaments (longitudinal filaments) on the spider web are very strong, but not sticky. >>>More
This condition in plum trees is caused by white spiders (two-spotted leaf mites) or red spiders. It is recommended to spray acaricides such as avermectin, sweep mite, and avida difen. Spider mites are highly susceptible to occurrence in poorly ventilated places. >>>More
Exchange-traded open-ended indices** are also commonly referred to as Exchange Traded Funds (ETFs)."etf"), is a kind of open-ended that is listed and traded on an exchange and has a variable share. >>>More
Breeds of sheep.
There are many, such as: sheep, lake sheep, goats, rock sheep, etc. >>>More
