What is the name of the spider bright yellow. Spider-bokad - a skilled and patient hunter from the arachnid family

The family of arachnids in its ranks has very beautiful and unusual creatures. They simultaneously look like spiders and crabs. Their name is also very interesting - bokohody spiders. Sometimes the creation of nature are simply incredible, as, for example, these spiders, able to jump, jump and move sideways. Because of this peculiar way of transportation, they got their name - bokhodas. They are also called spider horses and crabs spiders. It looks pretty and cute. Even those people who panicky fear spiders do not shudder at their sight. An interesting fact is that the web for these beautiful women is only needed to move from the upper tiers of plants to the lower ones. They also need spider strings for mating games. With the help of threads, these small animals (and spiders are just animals, and insects, as many people think) attract a partner.

Spider-bokhod: description, reproduction

The constitution of these animals is unusual. The front pair of legs is longer than the others, and they are also turned upwards. It is because of this structure of spider legs, these wonderful creatures move sideways. The body is flat and angular in appearance. Such a structure makes animals very similar to representatives of the crustacean family, therefore the second name of these creatures is crabs spiders. They can also move backwards exactly as their counterparts with claws.

The color of the spider-bokhodov depends on the environment in which they live. If on the ground, the spiders will be dark brown or gray. If the colors, the animals can be a different bright color. It is very difficult, almost impossible, to spot spiders. Nature gave them color, thanks to which they merge with their surroundings.

The mating season in bokhod spiders begins in early June. The male is looking for a female, draws her attention to his person and begins to care for. If the female reciprocates, then the spider-bokhod climbs back and moves to her sex hole. Then alternately introduces into it pedipalps, which contain seminal fluid. After the first mating, the spiders take a short break, rest, then re-mating. The female is ready to hide the cocoons from predators, hiding, attaching to the leaves or stems of plants.

Different types of spiders

Spider crab, or bokhod, is a general definition of many spider species, but most of these animals belong to the family of Thomisidae. In total there are about two thousand species of spider-bokhodov, which are divided into 170 genera.

The most famous are flower crabs. They hunt in colors and painted in bright colors. For example, in Uruguay, these animals imitate tropical flowers - the spiders are very beautiful and appear to be completely harmless.

Great hunters

Bokhok spider is very patient. Most of the time, these handsome men sit quite still in anticipation of prey. A spider's web is not needed for hunting, they do not use it to catch a victim.

The arms of the spiders of this species are the front legs. Outlining the target, the predator rushes to prey, using strong forelimbs, bites and injects poison. It helps these creatures to hunt their ability to merge with a plant, tree or earth. They perfectly adjust their “clothes” to the surrounding Appetite for a spider-crab excellent, it can eat for one hour 4 large bees. The prey, which is much larger than the hunter himself, is quite suitable for breakfast for a small predator.

Bokohody - a danger to humans

There are very few lovers of this type of insect like spiders. In most cases, a person experiences unpleasant emotions at their sight. The bokhok spider is not disgusting in appearance, but on the contrary - pretty. Only with a beautiful shell, these creatures still remain predators and can pose a threat to health. There are few cases of attacks on humans, but they still exist.

In the venom of these animals there are toxins that can poison the body. If bitten by a spider crab, then a person may experience a headache, weakness throughout the body. In this case, an urgent need to consult a doctor. The effects of a cute spider bite can be serious.

The squad of spiders includes more than 42,000 species of arthropods, among them there are quite a few creatures of the most unimaginable, and sometimes just cosmic forms. A special place in this niche is occupied by boochod spiders, which, no doubt, are among the most amazing spiders in the world.

Spider bokhody or spider crabs (lat. Thomisidae) - a family of small arthropods from the order of spiders. The body length is only 5-7 mm, males are almost half the size of females - 5 mm maximum for them.

First of all, the bokhoda spiders are unique with an incredibly strange body structure, which is very noticeable even with regard to the minimum size of the animal. The two front pairs of legs are 2 to 5 times longer and thicker than the third and fourth pairs, moreover, they are turned forward, and the males, in addition, are also covered with thick woolen cover.

Such an unusual shape of the limbs makes serious adjustments to the ways of movement of spider crabs: most of the time they have to move sideways, which in fact was the cause of the name of the family.

Modified front limbs - this is the main and only weapon of bokhodov. Its effectiveness is high enough to abandon the weaving of cobwebs and all other tricks.

Powerful front legs are the main weapon of this arthropod family.

Science knows more than 2,000 species of spider crabs that live on all continents and regions except Antarctica and Greenland. Almost all species have a masking coloration, which allows them to merge with their natural environment. So, for bokhodov living on flowers are characterized by bright and variegated colors, and for species who prefer to crawl on the ground - dark colors in brown and brown tones ...

Some of the Thomisidae species have good acting skills. In case of danger, they pretend to be dead, falling on their backs and pulling their front legs. Often this trick helps them escape.

Flower spider (lat. Misumena vatia) - view of spiders of the Bokohoda family ( Thomisidae).

Description

The species has sexual dimorphism in size and color. Males are 4 mm long, while females are up to 10 mm long. The male cephalothorax (prosoma) is blackish in color, the abdomen (opistosome) is white to yellowish in color with two dark long stripes. Both front pairs of legs with wide stripes of black and brown, both back pairs of legs of the main color of the abdomen.

In females, the color of the whole body varies from bright yellow to yellow-green and white. Often on the sides of the abdomen there are two long red stripes.

Spread

The species is distributed from the Arctic to the subtropical zones of the Holarctic, from Ireland and Portugal to Japan, as well as from Alaska to the southern border of the United States. With the exception of Iceland, the species inhabits all of Europe.

The species inhabits open habitats with a large number of flowering plants. Sexually mature spiders can occur from May to July.

Nutrition

A spider lurks its prey on flowers. It can change its color depending on the color of flowers. Only sexually mature females have this ability. They control the change in body pigmentation with their organs of vision. When stained in the yellow color in the cells of the epidermis enters the liquid, yellow dye, when stained in white, the pigment is transferred to the inside of the body. A yellow pigment can stand out with a long stay on white flowers also with a bowel movement.

The prey of the flower spider is various pollinating insects, for example, hoverflies, bees, wasps, butterflies or small beetles. They are often an order of magnitude larger than the spider itself. The spider grasps its prey with strong, widely spaced front legs and lightly bites to the head. Web not spins.

Breeding

Mating occurs in early summer. When the male finds the female, he climbs in front of her back. Then he moves to the abdominal side of the female and, in the abdomen-to-abdomen position, alternately inserts his pedipalps into the female's sexual opening. Then he again climbs on the back of the female, so that after a break he can mate with her again. In the end, the male leaves the female. The cocoons of eggs are hidden secretly from the sides of the flowers. Young spiders winter in the ground.

An excerpt characterizing the Flower Spider

He stopped in front of the Preobrazhensky Regiment, sighed heavily and closed his eyes. Someone from the retinue waved, so that the soldiers holding the banners came up and put them in shafts of banners around the commander-in-chief. Kutuzov paused for a few seconds and, apparently reluctantly, obeying the need for his position, lifted his head and began to speak. Crowds of officers surrounded him. He scrutinized the circle of officers, recognizing some of them.
  - Thank you all! - He said, turning to the soldiers and again to the officers. In the silence that reigned around him, his slowly pronounced words were clearly audible. - I thank everyone for their difficult and faithful service. The victory is perfect, and Russia will not forget you. Glory to you forever! - He paused, looking around.
  “Ngnu, nod his head,” he said to the soldier who was holding the French eagle and inadvertently lowered him in front of the banner of the Transfigurations. - Lower, lower, so here. Hooray! guys, - with a quick movement of the chin, turn to the soldiers, he said.
  - Hurray ra! - roared thousands of voices. While the soldiers were shouting, Kutuzov, bent at the saddle, bowed his head, and his eye lit up with a gentle, as if mocking, shine.
  “That's what, brothers,” he said when the voices fell silent ...
  Suddenly, his voice and his expression changed: the commander-in-chief stopped talking, and a simple, old man spoke, it was obvious that he wanted to tell his comrades what was necessary.
  There was a movement in the crowd of officers and in the ranks of the soldiers in order to hear more clearly what he would say now.
  - And that's what, brothers. I know it's hard for you, but what to do! Be patient; not long left. We will show the guests, rest then. For the service of your king will not forget. You find it difficult, but still you are at home; and they see what they have come to, ”he said, pointing to the prisoners. - Worse than the poor. While they were strong, we did not spare ourselves, but now we can regret them. They are people too. So guys?
  He looked around him, and in his stubborn, respectfully perplexed gazes fixed on him, he read sympathy to his words: his face grew lighter and brighter from the senile meek smile wrinkled with stars at the corners of his lips and eyes. He paused and lowered his head, as if in perplexity.
- And to say something, who called them to us? By sharing it, m ... and ... in g .... - he suddenly said, lifting his head. And, waving a whip, he galloped, for the first time in the entire campaign, drove away from the joyfully laughing and roaring cheers that upset the ranks of the soldiers.
  The words spoken by Kutuzov were hardly understood by the troops. No one would have been able to convey the content at first solemn and at the end of the ingenuously old-man's speech of the field marshal; but the heartfelt meaning of this speech was not only understood, but the very thing, the very feeling of a magnificent celebration in conjunction with pity for the enemies and the consciousness of their own right, expressed by this very old man’s good-natured curse, is the most (the feeling lay in the soul of every soldier and expressed a joyful, long-lasting cry. When after that one of the generals wondered if Kutuzov suddenly sobbed, apparently in great agitation, when one of the generals asked whether the commander-in-chief would come to the wheelchair.
