Yellow spider with red stripes. Poisonous flower spider

Spiders were among the earliest animals to live on earth. Despite the fact that the life span of spiders on the planet is quite significant, spider fossils are rare. According to historians, biologists and archaeologists, the first spiders on our planet appeared approximately four hundred million years ago. The ancestors of modern spiders were an arachnid insect, quite thick, large sizes. For a long period of time, this arachnid insect lived in water.

Tarantulas belong to the genus of higher spiders of the wolf spider family. This species is distinguished by its large body size (tarantulas can reach 3.5–7 cm in length), as well as the presence of poisonous glands. Most often everyone is called a tarantula large spiders. This is a very common misconception. For example, the same tarantula spider, despite its large size, has nothing to do with tarantulas. The habitat of tarantulas is an area devoid of moisture. Most often, representatives of this species can be found in the desert sands and steppes. Tarantulas feed small insects and animals, attacking them and killing them with poison. Another very common misconception is that a tarantula can pose a threat to humans. Yes, there can be a threat, but only for those who are terrified of spiders. Tarantula venom cannot kill humans. The bite of this spider can be compared to the bite of a wasp or hornet; it can cause swelling or severe pain shock, but does not poison a person.

There are several types of spiders in the world that people should be wary of. There are only two such individuals in the United States. These are the “brown recluse” (Loxosceles reclusa) and the “black widow” (Latrodectus mactans). The bites of these spiders are fatal due to their venom.
« Brown recluse" can be found in homes throughout the American West, hiding in cracks in floors. The bites of these spiders never heal. Anyone who wants to look at these terrible wounds is welcome here. So to know. But I warned you!

"Black Widow" is black with scarlet spots. This type of spider never attacks a person itself, only if people try to touch it. Distinctive feature these spiders have an unusually clear hourglass-shaped pattern on their bodies:

The female is a very poisonous spider. Males are less common and are harmless. Males have four pairs of red dots located along the sides of the abdomen. After mating, the female devours the male, hence the name “black widow”. But even among black widows, cannibalism does not occur in 100% of cases - it is rather a deviation from the norm. The female's bite is poisonous to humans; such a bite is accompanied by local pain, swelling, nausea, difficulty breathing and is sometimes fatal.

Another dangerous spider is the karakurt (Latrodectus tredecimguttatus). Quite common in steppe zone Central Asia, as well as in the Caucasus and Crimea. Karakurt is a small spider, its length usually does not exceed twenty millimeters. The habitat for karakurts is virgin lands, wastelands, banks of irrigation canals, and so on. People are susceptible to karakurt bites during the migration period of females (this is approximately June-July). The most poisonous are sexually mature females; the karakurt venom is fifteen times stronger than the venom of a rattlesnake. After a bite, a small spot remains on the body, which quickly disappears. Within fifteen minutes, sharp pain begins in the abdomen, lower back and chest, then the legs go numb. The patient becomes lethargic and cannot sleep due to severe pain. Recovery occurs in about three weeks, or even more. In severe cases and in the absence of medical care, death occurs already on the second day.

The words “spider” and “web” are quite familiar to all of us. We know well that the spider hunts with the help of its web. But it is not always the case. Some spiders do not use webs at all. A striking representative of a spider that does not use a web is the side walker. The spider simply camouflages itself in a flower and waits for prey. Due to its abilities, the spider can move not only forward and backward, but sideways, so it does not waste time turning around. And it is precisely these fractions of a second that are not enough for the victim to escape.

Jumping spiders have eight eyes, with two of them located at the back. The spider got its name from its ability to jump over a distance several times greater than its body length. And it's not about the legs, but about circulatory system. Before jumping, the spider's pressure increases several times, due to which the hind legs sharply straighten and the spider flies towards the victim, not forgetting to protect itself with the web.

The wolf spider uses its web as a rope to tie and hang its prey. His feet feed him. The wolf spider can walk on water and even dive for small tadpoles or fry.

The pirate spider uses its web as a signal. He stretches it in front of the mink and ties the ends to his legs.

Some of the flower spiders are able to change their color for more than a few days, usually between white and yellow, depending on the color of the flower on which they are resting.

Another interesting spider - Argyroneta aquatica. This is a water spider. If you translate the name literally, you get “the one who has the silver thread.” The spider, or rather the spider, is very small in size, only up to one and a half centimeters in length. However, the bite of this insect is very painful. Spiders live in water, or rather, under water. Habitat – Central and Northern Europe. Underwater, each spider has a bag woven from a web. Previously, it was believed that this bag was used to store food and to hide in times of danger. It was only recently that scientists discovered that the primary task of underwater bags is to store air. Spiders catch air bubbles underwater and carefully carry them into their bag on their paws, and the spiders react very strongly to the composition of the air inside the bag.

The male peacock spider Maratus volans uses dancing and colorful “outfit” to attract females:

The pattern on the abdomen of the spider Cyclocosmia truncata resembles ancient seal. The spider uses its disk as one of the methods of protection in cases of danger. They lead a sedentary lifestyle, so they do not stray far from their burrows. When threatened, it crawls into its hole head first and closes the entrance to the shelter with its hard disk.

Look unusual spiny spiders. These spiders are common in tropical and subtropical zones. There are six spines along the edge of their abdomen. They give the spider a more intimidating appearance, which helps scare away potential enemies:

They feed on small insects that they catch in their nets. The spider trap is a fairly strong net, reaching a diameter of 30 centimeters. It has practically perfect shape circle, in the middle of which there is a thin network. It serves as a base for the spider.

Yellow garden spider

Ever wish you knew more about the yellow garden spider crawling around tall vegetation and your home? You will be able to find interesting information Further

Screaming spiders crawling through the weeds, gardens and shrubs in your garden are yellow garden spiders. These yellow garden spiders are found in almost all sunny areas and gardens in the United States. They are usually observed around late summer and early autumn. They are typically called yellow-and-black spiders or black-and-yellow garden spiders. The yellow garden spider belongs to a group of spiders called ball weavers.

Scientific classification of yellow garden spider

Kingdom: Animals

Type: Arthopoda

Class: arachnids

Order: Araneae

Family: Araneidae

Genus: Argiope

Species: A. aurantia

The female yellow garden spider is about 19 to 28 millimeters. On the female's shell spider there is silver hair. It has eight eyes, which are attached to the lateral four eyes. These four eyes are closely set and present on two projections on either side of the carapace. The front legs are mostly black. The second, third and fourth pairs of legs are black with yellow or red thighs. She has an elongated oval abdomen. She has a distinct yellow and black pattern on her belly. The female has two anterior artificial bumps on her body. The male yellow garden spider is only 5 to 8 millimeters in length, and its legs are lighter in color than the female's legs. Male spiders have similar yellow and black bodies. Physical Characteristics of the Yellow Garden Spider

Range and habitat of the yellow garden spider

The black and yellow garden spider is found throughout the United States. However, it is often found in coastal areas of America. He lives in the eastern part North America, Ontario and Atlantic Canada. The yellow garden spider's habitats include sheltered areas between tall vegetation, house eaves, etc. that are protected from the wind.

Web of a yellow garden spider

The best way to identify yellow and black spiders is by using their web. These spiders are known for their webs, which consist of dry spokes supported by spiral silk threads. There are free zones that extend from the center of the spiral. During the day, the spider rests upside down in its web. At night, the spider is above the center with prominent zigzag stripes of bright white silk. You can read more about the definition of this spider.

Feeding habits of the yellow garden spider

The Yellow Garden Spider is a friendly, creepy, spine-tingling creature that will eat all the creatures in the garden. The female garden spider can hunt prey much larger than itself. These great sacrifices include grasshoppers, aphids, cicadas, chafers, butterflies, wasps, bees and other insects. These spiders also eat aphids, flies, ants, etc.

Garden Spider Reproduction

The yellow garden spider tends to breed only once a year. Males are looking for a female. Once they find their mate, they spin a small web next to hers. They begin to court the female, plucking threads from her web. Males always approach the female at a safe distance. This is because he never knows what he will find on her and she might attack him. After successfully mating with a female, he dies. Females probably eat their dead mate.

After mating at night, the female lays her eggs on a silky leaf. These eggs are then covered with another layer of cobwebs and a third brown layer of cobwebs. She creates a ball of sheets using her paws. This ball is called an egg sac, which is about 2-2.5 cm in diameter. This bag is suspended on its web near the center. One female spider can produce 1 to 4 egg sacs containing over 1000 eggs. She protects them as long as she can, and dies in the first severe frosts. Young yellow garden spiders are born in the spring. They are so small in size that they resemble dust particles and are carried by the wind to various areas.

Yellow garden spider bite

Now, is the yellow garden spider poisonous? Someone will certainly ask this question, especially after looking at the flashy colors. It has a certain amount of venom which is used to subdue prey. However, since humans are obviously not the target prey for these spiders, the venom does not cause much harm. Most likely, a female yellow garden spider will bite. This happens if she feels threatened while protecting her egg sac. If a yellow garden spider bites a person, the bite will simply cause a brief tingling sensation. It is likely that a small swelling, a red bump, may develop, which will go away in 2 to 4 days.

This is all about the yellow garden spider. It will remain an unnoticed guest in your garden and is unlikely to cause any problems. If you spot one during your morning walk on the trail or in the garden, leave it alone. The spider won't do much damage, and will go about its business when left alone again.

Flower spider (lat. Misumena vatia) - a type of spider of the family Sidewalking spiders ( Thomisidae).

A mature black widow is usually black and glossy. He is easily recognizable as hourglass red on the inside of her belly. The female measures 5 centimeters in length, weighs 25 grams and has a very round belly. The male is twice the size of the female but has longer legs. Shows red stripes with yellow on the back.

During the mating season, the black sheep searches for its mate, during which time it does not bite or feed itself. After mating, the black widow will deposit more egg sacs containing about 750 eggs. The bag measures 1cm in diameter, can be white or creamy and has a paper texture. One summer, a woman can place between 4 and 9 bags. Incubation lasts 14 days, and young widow spiders are cannibals. 1-12 black widow spiders survive from the bag.

Description

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

The male widow reaches maturity after 70 days and dies at the age of one or two months. This happens because a woman sometimes eats the man she just slept with. Females mature at the age of 90 and live 1-5 years. The black widow spits canes that are not of a specific shape or size. varies as location, but most changes as shape. The canvas comes from fluid removed from the abdominal glands. When leaving the abdomen, the fluid increases due to distension.

The canvas of a black widow's web is stronger than that of any other spider. The black widow is shy and active more at night, staying longer inside the canvas and only coming out when threatened. A woman only bites when she is disturbed. The black widow produces a dangerous human venom, but the mortality rate from biting is quite low.

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

Spreading

The species is distributed from the Arctic to 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 lives throughout Europe.

The black widow is a spider that inhabits insects. Because its web is sticky, it can capture its prey along with it. His food lacks bugs, including kitchen flies. The black widow kills its prey by injecting poison. It will then make a hole in its body and begin sucking all the liquid into its prey. The black widow's digestive juice will also be injected into the victim's body to help crush body parts. The black widow will leave only the outer shell of lime.

The black widow is not necessarily beneficial to humans beyond eating insects. It can often be found near people's homes, helping to eliminate pests. The black widow can be a dangerous spider. He has 15 more dangerous poisons than a snake with bells. But when it bites, the black widow injects only a small portion of its venom, while the bell snake injects all of its venom into the victim. However, if more black widow spider venom is injected into humans, it will most likely die.

The species inhabits open habitats with big amount flowering plants. Mature spiders can be found from May to July.

Nutrition

The spider lies in wait for its prey on flowers. It can change its color depending on the color of the flowers. Only sexually mature females have this ability. They control changes in body pigmentation with their visual organs. When stained yellow, a liquid, yellow dye enters the cells of the epidermis; when stained yellow, White color the pigment is transferred to the inside of the body. Yellow pigment can be released during prolonged exposure to white flowers, also through bowel movements.

A black widow spider bite causes abdominal pain and swelling of the leg muscles. Less serious symptoms include dry mouth, sweating, and swelling of the eyelids. If a young person aged 16 or older is bitten, they should go to hospital. Most deaths in these people are due to heart or pulmonary failure. Healthy people that bite will recover in 2-5 days if they have proper care.

The black widow is not necessarily beneficial to humans beyond eating insects. It can often be found near people's homes, helping to eliminate pests. The black widow can be a dangerous spider. It has 15 more dangerous poisons than the bell snake. But when it bites, the black widow only injects a small portion of its venom, while the bell snake injects all of its venom into the victim. However, if more black widow spider venom is injected into humans, it will most likely die.

The flower spider's prey includes various pollinating insects, such as hoverflies, bees, wasps, butterflies or small beetles. They are often an order of magnitude larger than the spider itself. The spider grabs its prey with strong, widely spaced front legs and delivers a lightning-fast bite to the head. Doesn't weave a web.

Reproduction

Mating occurs early summer. When the male finds a female, he climbs from the front onto her back. Then he moves to the ventral side of the female and, in a belly-to-abdomen position, alternately inserts his pedipalps into genital opening females. Then he climbs back onto the female's back to mate with her again after a break. Eventually, the male leaves the female. Egg cocoons are located secretly on the sides of flowers. Young spiders overwinter in the ground.

Excerpt characterizing the Flower Spider

He stopped in front of the Preobrazhensky Regiment, sighed heavily and closed his eyes. Someone from the retinue waved for the soldiers holding the banners to come up and place their flag poles around the commander-in-chief. Kutuzov was silent for a few seconds and, apparently reluctantly, obeying the necessity of his position, raised his head and began to speak. Crowds of officers surrounded him. He looked carefully around the circle of officers, recognizing some of them.
– Thank you everyone! - he said, turning to the soldiers and again to the officers. In the silence that reigned around him, his slowly spoken words were clearly audible. “I thank everyone for their difficult and faithful service.” The victory is complete, and Russia will not forget you. Glory to you forever! “He paused, looking around.
“Bend him down, bend his head,” he said to the soldier who was holding the French eagle and accidentally lowered it in front of the banner of the Preobrazhensky soldiers. - Lower, lower, that’s it. Hooray! “Guys,” with a quick movement of his chin, turn to the soldiers, he said.
- Hurray rah rah! - thousands of voices roared. While the soldiers were shouting, Kutuzov, bending over the saddle, bowed his head, and his eye lit up with a gentle, as if mocking, shine.
“That’s it, brothers,” he said when the voices fell silent...
And suddenly his voice and expression changed: the commander-in-chief stopped speaking, and a simple man spoke, an old man, it is obvious that he now wanted to tell his comrades the very thing he needed.
There was a movement in the crowd of officers and in the ranks of soldiers to hear more clearly what he would now say.
- Here's what, brothers. I know it’s difficult for you, but what can you do? Be patient; not long left. Let's see the guests out and then rest. The king will not forget you for your service. It’s difficult for you, but you’re still at home; and they - see what they have come to,” he said, pointing to the prisoners. - Worse than the last beggars. While they were strong, we did not feel sorry for ourselves, but now we can feel sorry for them. They are people too. Right, guys?
He looked around him, and in the stubborn, respectfully perplexed glances fixed on him, he read sympathy for his words: his face became lighter and lighter from an senile, meek smile, wrinkled like stars in the corners of his lips and eyes. He paused and lowered his head as if in bewilderment.
- And even then, who called them to us? Serves them right, m... and... in g.... - he suddenly said, raising his head. And, swinging his whip, he galloped, for the first time in the entire campaign, 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 be able to convey the content of the field marshal’s first solemn and at the end innocently old man’s speech; but the heartfelt meaning of this speech was not only understood, but that same, that very feeling of majestic triumph, combined with pity for the enemies and the consciousness of one’s rightness, expressed by this, precisely this old man’s, good-natured curse - this very (feeling lay in the soul of every soldier and expressed himself with a joyful cry that did not cease for a long time. When after this one of the generals turned to him with a question about whether the commander-in-chief would order the carriage to arrive, Kutuzov, answering, unexpectedly sobbed, apparently in great excitement.

The arachnid family has very beautiful and unusual creatures in its ranks. They look like both spiders and crabs at the same time. Their name is also very interesting - side-walking spiders. Sometimes the creatures of nature are simply incredible, like, for example, these spiders that can hop, jump and move sideways. Because of this unique method of movement, they got their name - sidewalkers. They are also called jumping spiders and crab spiders. They look cute and cute. Even those people who are terrified of spiders do not shudder at the sight of them. An interesting fact is that these beauties need a web only to move from the upper tiers of plants to the lower ones. They also need spider threads 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.

Side-walking spider: description, reproduction

The physique of these animals is unusual. The front pairs of legs are longer than the others, and they are also turned upside down. It is because of this structure of spider legs that these wonderful creatures move sideways. The body appears flattened and angular. This structure makes the animals very similar to representatives of the crustacean family, which is why the second name for these creatures is crab spiders. They can also move backwards just like their clawed counterparts.

The color of sidewalk spiders depends on the environment in which they live. If on the ground, the spiders will be dark brown or gray. If on flowers, then the animals can be of different bright colors. It is very difficult, almost impossible, to notice spiders. Nature gave them a color that makes them blend into their surroundings.

The mating season for sidewalk spiders begins in early June. The male looks for a female, attracts her attention to him and begins to court her. If the female reciprocates, the sidewalk spider climbs onto her back and moves to her genital opening. Then he alternately introduces the pedipalps, which contain seminal fluid. After the first mating, the spiders take a short break, rest, and then mate again. The female hides the finished cocoons from predators by attaching them to the leaves or stems of plants.

Different types of spiders

The spider crab, or sidewalker, is general definition many species of spiders, but most of these animals belong to the family Thomisidae. In total, there are about two thousand species of side-walking spiders, which are divided into 170 genera.

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

Excellent hunters

The sidewalk spider is very patient. Most of the time, these handsome guys sit completely still, waiting for prey. Sidewalkers do not need a web for hunting; they do not use it to catch prey.

The weapons of spiders of this species are the front legs. Having identified a target, the predator rushes at the prey using its strong forelimbs, bites and injects poison. Their ability to merge with a plant, tree or earth greatly helps these creatures hunt. They perfectly adapt their “clothes” to their surroundings. The crab spider has an excellent appetite; it can feast on 4 large bees in one hour. Prey that is much larger than the hunter himself is quite suitable for breakfast for a small predator.

Sidewalkers are a danger to humans

There are very few lovers of this type of insect such as spiders. In most cases, a person experiences unpleasant emotions when they see them. The side-walking spider is not disgusting in appearance, but on the contrary, cute. 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.

The venom of these animals contains toxins that can poison the body. If bitten by a crab spider, a person may experience a headache and weakness throughout the body. In this case, you must immediately consult a doctor. The consequences of a cute spider bite can be serious.

Spiders are arthropods that belong to the class of arachnids. Representatives of this class, today, there are about 40 thousand species. They differ from each other in their way of life, appearance, type of food. In nature there are a wide variety of types of spiders: the smallest and harmless spiders(0.37 mm), as well as the most dangerous spiders and even the most poisonous spiders in the world (up to 25 cm). And in this article we will tell you about several amazing and interesting species.

Tarantula spider – Theraphosidae

The tarantula spider is perhaps the most big spider in the world, or rather the family of tarantula spiders (Theraphosidae). Some members of this family can reach 30.5 cm in leg span, such as the king baboon, black tarantula and purple tarantula. The body of tarantulas is always densely covered with long and short hairs. Body color can be either gray-brown or bright colors (red, blue, red). Tarantulas live in countries with hot climates (Africa, South America, Oceania, Australia). These spiders inhabit abandoned nests of birds and rodents or dig holes near tree trunks. Mainly active in evening time. Then they go hunting or catch a prey running nearby. Tarantulas feed on insects, small birds and rodents. These spiders breed in late summer. The female lays eggs in a cobweb cocoon, which she carries with her and does not lose sight of. They protect the offspring, so that the spiderlings that emerge from the cocoon sit on the mother’s abdomen for some time. But soon they begin to lead an independent life. The tarantula's venom paralyzes the victim and decomposes its entrails, then the spider sucks out the contents of the victim's body. For humans, the tarantula's venom is not dangerous, but quite painful. The bite site bakes, hurts and swells, sometimes turning yellow. But these symptoms go away after a few weeks.

Cross spider – Araneus

Crossworts are members of the orb weaver family (Araneidae). They belong to the contract web spiders. They have an egg-shaped convex abdomen, on which there is a pattern in the form of a cross. Body color ranges from gray to red. They are covered with long bristles, sparsely distributed throughout the body and densely covered with short, thin hairs. Body length in males is 10-11 mm, in females – 17-40 mm. About 30 species of crosses live in the CIS and Russia. These spiders are active in the evening. They deftly weave webs that catch many small insects. Mating and egg laying occurs in the fall. The female lays eggs in a web cocoon and hides it under the bark or other secluded place. In the spring, spiderlings emerge from the cocoon. By the end of summer, a new generation of spiders grows up, and their mother dies. The cross spider is poisonous, but it is not dangerous to humans. Its bite is painful, but the burning and swelling at the site of the bite goes away after a few hours.

Karakurt spider - Latrodectus tredecimguttatus

This is not a large black spider at all. The body of the female (10-20 mm) is completely black, which is why she is also called a black widow, the body of the male (4-7 mm) is also black, but with bright red spots on the abdomen (usually 13 spots ). The karakurt spider lives in Central Asia, Iran, Afghanistan, on the shores of the Mediterranean Sea, in North Africa, Southern Europe, Kazakhstan, southern Russia and Ukraine. They prefer the slopes of ravines, virgin wormwood, wastelands, and the banks of irrigation ditches. Karakurts inhabit abandoned rodent burrows and ventilation systems, entwining the entrance with cobwebs. In such dens, females and males mate at the end of summer. The female lays her eggs in a cocoon of cobwebs and hangs it in her den. In spring, spiderlings emerge from cocoons. Karakurts feed on small insects. Their venom is toxic to large animals and people. There is a burning sensation and swelling at the site of the bite. After 10-15 minutes, the poison spreads throughout the body and the person experiences pain in the chest and abdominal area. Dizziness, nausea, sweating, rapid heartbeat, and delirium also occur. And if you don’t provide it in time medical care, death is possible (in most cases). Karakurt bites through the skin only 0.5 mm, so it is recommended to cauterize the bite site with a lit match within 2 minutes after the bite.

White karakurt - Latrodectus pallidus

Image of white karakurt

This is a white spider, with long legs and a round abdomen. The abdomen is white or milky in color, with 4 indentations. The legs and cephalothorax are yellow or light brown. White spider has a body 10-20 mm long. Females are larger than males. White spiders weave a web in the shape of a cone, which is connected to a trapping net. They live in North Africa, the Middle East, Iran, Kazakhstan, Turkmenistan and Azerbaijan. The white karakurt spider is not aggressive, but its poison is toxic and can cause complications. Children and the elderly are most susceptible to the effects of the poison. Toxicological studies have shown that the poison of the white karakurt is similar to the poison of the karakurt (Latrodectus tredecimtugattus). If you are bitten by this spider, you should consult a doctor.

Camel spider - Camel spider

The camel spider has many names: phalanges, bihors, salpugs, barbers, barbers, wind scorpion. The body (5-7 cm) is slightly oblong, light and dark red, densely covered with long, thin hairs. The camel spider's body shape is similar to a scorpion, especially with its chelicerae (claws). With them he is able to bite through a human nail and even small bird bones. He also uses his chelicerae to trim hairs and feathers from his victims and place them in his home. The camel spider lives in the desert regions of Asia, Africa, America, and Europe. Phalanx spider nocturnal predator. It is practically omnivorous and carnivorous, feeding on various insects, rodents, and lizards. Camel spiders have eyes like scorpions: 2 compound eyes in the middle and one on each side of the cephalothorax. Compound eyes are highly responsive to movement, so these spiders are incredibly fast, up to 53 cm/s (1.9 km/h).
The camel spider is not poisonous, but it does have an incredibly painful bite. And also on its chelicerae the remains of the tissues of the previous victim can rot, which can cause serious inflammation.

Jumping spiders – Salticidae

Jumping spiders or jumping spiders are a family of araneomorphic spiders that includes 610 genera and 5,800 species. Live in tropical forests, in deserts, semi-deserts, in temperate zone forests and mountains. These are small spiders, up to 2 cm long. The body is pubescent. These spiders have well-developed vision. They have 8 eyes, thanks to which they see 360º degrees. Jumping spiders differ from each other in body shape, color and range. There are the following types of jumping spiders:
- the golden jumping spider lives in the south-east of Asian countries, and is characterized by a long abdominal part and a large first pair of legs. The body has a very peculiar golden color. The length of the male rarely exceeds 76 mm, and the females are larger;

- Himalayan jumping spiders are the smallest spiders. They live high above sea level, in the Himalayas, where their only prey is the occasional small insect that is blown onto the mountain slopes by strong winds;

- The green jumping spider lives in New Guinea, New South Wales and Queensland. Often found in Western Australia. The male has a very bright color, and his body is decorated with long white “whiskers”;

- The red-backed species of jumping spider settles in relatively dry areas. The red spider is often found on coastal dunes or oak woodlands in North America. These red spiders are unique in that they are able to build tube-like silken nests under rocks and on the surface of vines;

- the species Hyllus Diardi has a body up to 1.3 cm long. Compared to other types of jumping spiders, it does not weave a web, therefore, to catch prey, it attaches a silk thread to some support, and then jumps from such a peculiar “bungee” onto its victim;

- the ant jumping spider looks very similar to an ant and is most often found in tropical zones from Africa to central Australia. Body color can vary from light yellow to black.

Jumping spiders are unique in that they can jump long distances (up to 20 times their body size). Before jumping, they cling to the substrate with a web (thus securing their jump), then push their body out with their hind legs. Jumping spiders are absolutely harmless to humans. They have poison, but it has no effect on humans, and their bite is almost painless.

Argiope bruennichi or spider wasp - Argiope bruennichi

Argiope has the second name of the wasp spider, since the color of the body and the shape of the abdomen resemble a wasp. Body length 2-3 cm (leg span). The abdomen is elongated with bright stripes, the predominant colors are yellow, white, and black. The legs are long, thin, and mostly in an X-shaped position. The spider wasp lives in Kazakhstan, Asia Minor, Central Asia, China, Korea, India and Japan, North Africa, Southern and Central Europe, Crimea, and the Caucasus. These spiders are also found quite often in Russia. Argiope belongs to the spiders of the orb-weaving spider family (Araneidae). It is typical for these spiders to weave a wheel-shaped web, and have a stabilimentum (zigzag pattern) in the center. This is a forest spider. It very often settles on lawns, forests, gardens, in tall grass, between tree branches. The wasp spider feeds on various insects. Mating occurs after the female has moulted, while her body remains soft. The female lays eggs in a large cocoon (outwardly resembling a plant seed pod) and places it next to the hunting web. The spiderlings emerge from the cocoon at the beginning of autumn and settle downwind on cobwebs. The wasp spider is not dangerous to humans. Its venom may only cause slight redness, swelling and pain, but these symptoms go away very quickly.

Wolf spiders – Lycosidae

Wolf spiders are a family of araneomorph spiders that number 2,367 species. The body color is usually gray-brown. The body is covered with small short hairs. Some species reach more than 3 cm (leg span). The wolf spider lives almost everywhere except Antarctica. He prefers rain forests, meadows, hiding under fallen leaves, stones, wood. They don't weave webs. These are earth spiders, so they live in a hole, which is only covered with cobwebs inside. If this is the private sector, you can easily stumble upon it in the basement. If there is a vegetable garden nearby, he can easily get into your cellar. Active at night. The wolf spider hunts insects or catches those who run near its burrow. This spider is a good jumper. He can jump on the victim, securing himself with a web. Mating occurs in the summer. After mating, the female lays eggs in a cocoon that she carries at the end of her abdomen. After 2-3 weeks, the spiderlings emerge from the cocoon and climb onto their mother’s abdomen. They sit like this until they learn to get their own food. The wolf spider is not dangerous to humans. Its bite is equivalent to a bee sting, which causes itching, swelling and redness, which goes away fairly quickly.

Harvesting spiders – Pholcidae

This family has about 1000 species of spiders. Harvesting spiders have a small body and long thin legs. Body size 2-10 mm. The length of the legs reaches 50 mm. Body color is grayish or reddish. Harvesting spiders are ubiquitous. Some species live in people's homes. There they find warm and dry places, mainly near windows. They feed on small insects. These spiders weave large webs in a chaotic manner. The web is not sticky, but when the victim tries to get out of it, it becomes even more entangled. After mating, females lay eggs in a web cocoon, which they attach to the side of the trapping nets. For humans, harvest spiders are absolutely harmless. Their venom is safe, and the bite cannot be felt.

Goliath tarantula - Theraphosa blondi

This giant spider considered the largest in the world. The span of its legs reaches 30 cm. In Venezuela (1965), one of the representatives of this species was listed in the Guinness Book of Records. Its leg span was 28 cm. It is believed that the leg span of Heteropoda maxima is even longer, up to 35 cm. But this type has a small body and long thin legs. So he is small compared to the massive goliath.
The body of the goliath is light or dark brown, densely covered with short hairs. They live in burrows, the entrance of which is covered with cobwebs. This one lives huge spider in the tropical forests of Suriname, Guyana, Venezuela, and northern Brazil. It feeds on various insects, rodents, frogs, lizards and even snakes. The life expectancy of females is 15-25 years, males - 3-6. These spiders are amazing in that they are able to make a hissing sound by rubbing their chelicerae; the ability to shake hairs from the abdomen into the enemy’s face, which cause swelling of the mucous membrane. The goliath tarantula also has large and sharp chelicerae (claws), with which it can bite very painfully. Their venom is not dangerous to humans; the symptoms are the same as after a bee sting.

Runner spider (soldier spider, banana spider, wandering spider) – Phoneutria

The Brazilian spider is the most poisonous spider in the world. The length of its body reaches 15 cm. The body is pubescent, gray-brown in color. He lives in Central and South America. The runner spider feeds on insects, frogs, lizards, and small birds. Lives in burrows, under leaf litter. But very often, secluded places in people’s homes become its home. It is often called banana because it is often found in boxes of bananas. These scary spiders have incredibly toxic venom that causes instant death, which is why they are the most poisonous spiders in the world. Their venom contains the neurotoxin PhTx3, which paralyzes all muscles in the human body, causing suffocation and then death. Only 2-6 hours pass between the bite and death. Old people and children are most exposed to the runner spider's venom. Today there is a vaccine that neutralizes the effect of the poison, so if you are bitten by a spider, you should immediately consult a doctor.

As you can see, representatives of arachnids are so different: some of them are pleasing to the eye, while the sight of others makes the blood freeze in your veins, some can be picked up or kept in your home as a pet, and some sow fear and bring instant death. Now you know which types of spiders are absolutely harmless and which ones you need to stay away from. The good news is that dangerous species Spiders are not found in our area, but mainly in tropical countries. But you never know what can happen... Nature is absolutely unpredictable.

It happens here unusual spider. Not only does it not weave webs, it is also a chameleon spider, capable of changing its color depending on its surroundings. This is about flower spider, or scientifically Mizumena clubfoot(lat. Misumena vatia). As the name implies, this spider hunts, waiting for its prey (pollinating insects) on flowers. It is able to successfully camouflage itself thanks to its coloring - this spider is white, but if it hunts yellow flowers, it can change color to yellow. This is what the females of this species look like. Males are much smaller and darker in color. I happened to observe the following scene: among the bird cherry flowers, a large white spider caught its prey - a centipede mosquito. Like many other species of spiders, the male flower spider is much smaller than the female, and can accidentally be confused with prey. Other spiders get out of this situation by bringing a gift in the form of prey packaged in the web, but here the male sneaks up on the female while she is busy with the caught mosquito. And while the “bride” is busy with lunch, the “groom” manages to ride the female’s abdomen.

Flower spider(lat. Misumena vatia) or Mizumena clubfoot- type of spider family side-walking spiders (Thomisidae). Males and females of this species look different. Scientifically, this division is called sexual dimorphism.

Males are 4 mm long, while females are up to 10 mm long. The male has a blackish cephalothorax (prosoma), and a white to yellowish abdomen (opisthosoma) with two long dark stripes. Both front pairs of legs have wide stripes of black and brown, both rear pairs of legs are the main color of the abdomen.

In females, the color of the entire body varies from bright yellow to yellow-green and white. There are often two long red stripes on the sides of the abdomen. The species is distributed from the Arctic to 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 lives throughout Europe. The species inhabits open habitats with a large number of flowering plants. Mature spiders can be found from May to July.

The spider lies in wait for its prey on flowers. It can change its color depending on the color of the flowers. Only sexually mature females have this ability. They control changes in body pigmentation with their visual organs. When painted in yellow A liquid, yellow coloring substance enters the cells of the epidermis; when painted white, the pigment is transferred to the inside of the body. Yellow pigment can be released during prolonged exposure to white flowers, also through bowel movements.

Flower spiders are predators; they are not afraid to attack even insects larger than themselves. Spiders wait for their prey for a long time, disguised as the terrain (flowers). They are very mobile and when the long-awaited profit appears, they quickly grab it with their feet and inject their paralyzing poison into the body of the victim. Then after a while they suck everything out of her nutrients, leaving one shell.

Mating occurs in early summer. When the male finds a female, he climbs from the front onto her back. He then moves to the ventral side of the female and, in a belly-to-belly position, alternately inserts his pedipalps into the female's genital opening. Then he climbs back onto the female's back to mate with her again after a break. Eventually, the male leaves the female. Egg cocoons are located secretly on the sides of flowers. Young spiders overwinter in the ground.
