There is a big circle in the middle, what spider?

A spider with a large circle in the middle may be a globular ring spider (physocyclus globosus). This spider belongs to the kingdom Animalia, phylum Arthropods, Arachnids, Arachnidae, Arachnidae, Ghost Arachnidae, Ring Spider genus. Its key features include:

1.The body is divided into cephalothorax and abdomen, the anterior end of the cephalothorax is transverse, the head can move, and the thoracic part has two segments in front and back, which are connected by the neck segment, the anterior segment is short and thick, and the posterior segment is thin and long.

2.There are as many as 8 feet, 2 chelicerae and 6 feet are touchable.

3.The abdomen is small, long cylindrical, with a pair of raised longitudinal ridges with a small circle in the middle of each ridge, and many horizontal stripes on both sides of the ridge.

Ghost spiders, because this type of spider likes to hide in the dark of the room, so it is called "ghost". Ghost spiders are generally not large, belonging to medium-sized spiders, generally about 6 mm in length, cephalothorax wide and round, and extremely slender feet, more than 3 times the body length, so it is also called "long-legged spider". They are accustomed to living in indoor corners, under washbasins, in the cracks of cabinets, and without sticky simple webs, they are indoor spiders.

Blind spiders or ghost spiders are relatively small and have slender legs, and what you see at home is generally ghost spiders.

This is a green crab spider of the family Crab Spider, and its name is Young Leaf Spider.

Young leaf spider (Crab spider family) The female spider is 8 - 12 mm long, pale green, with a small black-brown spot on each side in front of the middle fossa, the eyes have yellowish-white borders, the abdomen is spindle-shaped, the ventral dorsal has 4 - 5 pairs of small black-brown spots, the first pair of steps is developed, the male spider is 8 mm long, the cephalothorax is greenish-brown, and the legs are dark and early brown above the base of the spikes.

There is only one species in this genus, mainly distributed in low-altitude mountainous areas, often foliar activities, body color with individual changes into the environment, waiting for prey to come to the door. Most species of crab spiders have a short cephalothorax and abdomen, a body length of several millimeters, a distended tentacle, and a habit of raising the forward steps when moving. Most species have a short cephalothorax and abdomen, with their feet stretched out to the left and right, and can walk sideways or backwards, like crabs, hence the name.

Habits

The cephalothorax and abdomen are short and wide, the body length is several millimeters, the tentacles are swollen at the ends, the anterior feet are habitually raised when moving, the crab spiders do not form webs, and often lie in the flowers and grasses waiting to prey on passing insects, sometimes raising the first pair of feet to open to the left and right.

Egg sacks are laid on leaves or tree trunks, and females often lie on them to guard them, but usually die before the larvae hatch. It mainly lives in low altitude areas, in flowers and grasses or in bean fields, or in cotton fields and wheat fields close to bean fields to hunt pests.

1. This is only a subgenus of the garden spider family, and the possible species is the big-bellied garden spider.

2. This kind of slightly toxic, timid, theoretically startable type (not recommended, the teeth are big and you can see blood).

3. At that time, the biological species had no value as a pet, and they could be raised, but the space for weaving nets was large.

The first is the round web that we most commonly see, which is the so-called Bagua web, the web is on a plane, and the spider silk is arranged radially from ** to the surroundings, and then connected with a lot of horizontal filaments in the middle.

The second type is called a funnel web, which is shaped like a funnel and has a silk tube next to it for spiders to enter and exit when moving on the web.

The third type of network is triangular in shape, which is called triangulation.

1 Although the vast majority of spiders secrete spider silk, only some of them form webs.

2 Many spiders have a special structure on the tail of their bellies—a spinl. The weaver produces a special type of mucus that is ejected from the six holes at the end of the tail and hardens into elastic and strong spider silk when it comes into contact with the air. Some spider silk is sticky, and some spider silk is not.

A spider's web is made of these two types of silk.

3 When spiders build webs, they often spit out a few slender filaments first, and rely on the wind to blow them, fix these filaments at the other end, form a square or regular shape outline, and then radiate the silk threads from the center to the periphery, and then form a circular skeleton from the center point outward, these threads are not sticky. After the skeleton is formed, the spider then forms a web from the outside to the center in the opposite direction, and these threads are sticky and used to catch insects. Spiders are constantly producing mucus in their stomachs, so they can constantly draw silk and weave a lot of webs.

This can be used to glue insects.

Because the spider follows the rotation, and it is so strong, it also saves spider silk.

The female spider is 13 - 15 mm long, the male is 8 - 12 mm, the cephalothorax and dorsal plate are gray-green to yellow-green, and there are three black longitudinal bands on the back of the abdomen.

Scientific name in Chinese. Great silver-bellied spider.

1. This is just a species of the genus Golden Spider in the garden spider family.

2. The specific species is the pleasing golden spider.

3. This kind of micro-poison, timid, and basically harmless to people.

4. The biological species of the year basically have no feeding value.

The golden spider is characterized by writing white symbols on the Internet.
