Message about arachnids house spider. Family Agelinidae, funnel spiders, or funnel spiders Agelenidae

House spiders (lat. Tegenaria) - a genus of spiders from the family of agelenic funnel spiders. Three common species are the stray house spider (Tegenaria agrestis), the house spider (Tegenaria domestica), and the giant house spider (Tegenaria duellica).
Stray house spider (Tegenaria agrestis) (considered the most poisonous spider; although not scientifically proven), the house spider (Tegenaria domestica) and the giant house spider (Tegenaria duellica).

If black soap works wonders on soil sheen, it's also a good spider repellant. To prevent these little hairy creatures from entering the corner of your house, make it a habit to spray every strategic spot with this house repellant, which is a recipe: pour 1 liter of water into a container where you add 5s. black liquid soap. Mix well and pour the resulting solution into a clean, dry spray bottle. Spray this repellent every week in strategic corners.

According to our ancestors, spiders do not like chestnuts or chestnuts. To make them run from your home, simply toss one of these fruits, which you have previously cut into two, in the corners of your home. Also place chestnut leaves around the edges of your windows.

The house spider, this is its informal name, Tegenaria. Received such a name solely because it lives indoors. Female and male house spiders do not differ much in size, but as a rule, female house spiders can live indoors for several years. The active time of day for these types of spiders is night, at night the males are very active, they move around the house in search of a female to mate with.

advice from our grandmothers

Spiders don't like cayenne pepper. To make them run away, here is a terrible potion.

  • Holes and cracks in the walls are the ways the spiders make to keep warm.
  • By filling the cracks, you will limit the presence of these small animals.
Spiders are a sign of a healthy home.

Often, a house spider can be confused with a wandering spider (it is also called a biting spider), since they look very similar in appearance. Biting spiders are quite dangerous for people; ulcers appear on the human skin at the site of the bite, which heal very slowly. But, unlike the stray, ordinary house spiders cannot bite through the skin of a person, or their poison is very weak to cause any harm to people.

Contrary to popular belief, spiders are not all black and hairy, some species are colorful and tiny. Let's get a little better acquainted with those who scare people. Discrete most of the year, the latter is more noticeable in autumn. People think the spiders come because it's cold. “False,” answers Christine Rollard, a spider biologist at the National Museum of Natural History of Paris, stating that this is the breeding season of the species. These are the men who go out at dusk. This is really the moment when he is looking for a partner to mate with.

Agelenidae often aggressive, but almost not dangerous. In their behavior, they are nocturnal, and they often compete with spinners detachment " Spider". Genus Malthonica- perhaps the only one whose representatives hunt as extensively during the day as at night, so they are least likely to be seen on the web. The family itself is quite aggressive towards its own relatives, despite mutual assistance.

Women in our homes, they stay in the net, waiting for their prey. In fact, they are sedentary and hunt in their web, so we don't necessarily see them because they don't move, it's passive hunting. It has few natural predators. It feeds mainly on insects, usually smaller than them. In adulthood, she consumes the equivalent of a fly every three weeks.

Spiders "are natural insecticides," says the biologist, "a house with spiders is a healthy house." Sometimes spiders are found in the bathroom or sink. They didn't go through the pipeline, "they just fell, they can't go back alone, they need something to hold on to," says Christine Rollard.

Unequal reputation in relation to venomous bite has a genus Tegenaria, namely - Tegenaria agrestis(meadow spider). In Europe, not a single case of serious consequences after the bite of this spider was recorded. However, many American arachnologists have approved the involvement of the meadow spider in serious medical consequences of bitten patients (in most cases, they ended in skin necrosis).

After three weeks to one month of pregnancy, the female lays 40 to 60 white eggs. These eggs are protected in a cocoon until they hatch. The young remain in the mother's web until their third molt. The female can live for two years, sometimes three for some. And the role of each animal is important in the balance of nature.

So don't think that spiders are coming home to warm up in your house, they are already present at home. Men or women? You can tell the male from the female. Spiders have four pairs of locomotor legs and a pair of pedipalps in front. In males, at the end of the latter, some types of boxing gloves are formed, which are actually copulatory bulbs. In women, these "balls" do not exist.

On the general plane, Tegenaria does not have enough toxins in its venom to create a similar effect. Most likely, an infection that penetrated the skin through chelicerae could play a big role in these situations. This is a significant factor, since not all spiders are able to bite through it.

Tegenaria brownie, aka house spider or Tegenaria Domestica (from tegens ara - “cover cover”) refers to synanthropic species that prefer to coexist next to humans. It is also said that a swallowed house spider brings good luck.

Animal or human and carry dangerous infections that can lead to difficult problems and even death. Spider spider can be found in many places in the United States, but also in other countries. Spider spider can also be found in Japan, India, Europe, Africa and Australia. The yellow-hot spider knitted special web bags on the walls and ceilings and hid in any of them during the day. Due to the fact that the crocheted bags, and not the usual spider webs, the name "Yellow Spider Spider" is called.

For centuries, people have tried to protect themselves from yellow-eyed spiders invading their homes, because its venom can cause great damage to the body. Today, the "Yellow Spotted Spider" is recognized as one of the greatest pests, and in places where it is very common, the only way to eradicate it is the intervention of insect and pest control specialists.

Description

Tegenaria is a family of funnel spiders that erect housing in the form of a funnel pipe, to which they attach a triangular web up to 3 square meters. dm.

The female is always larger than the male, sometimes one and a half, or even 2 times. The standard male rarely grows more than 9-10 mm, taking into account the span of the paws, while their girlfriends reach up to 15-20 mm.

Spider spider characteristics

yellow spider has dimensions from 5 to 10 millimeters. The yellowish spider has a pale beige, whitish or yellowish hue, with a slight hint of green. The jaws of the jellyfish jellyfish as well as the tops of their legs are dark brown - this is the reason why the spider's legs look dark from a distance. In the upper part of the stomach, the yellow-eyed spider has a dark spot.

The front legs of the yellow spider are longer than the other 6 legs. At the mouth of the Yellow Spider there are miniature tentacles ending in clips - with which the spider can catch small insects, and then help with the tentacles to hold the victim, sucking in its vital juices.

The color of the body is dominated by brown (slightly lighter or darker), complemented by leopard stains. Sometimes the pattern on the abdomen is more like a herringbone. Males are darker than females, and the darkest, almost black shade falls on the bases of powerful limbs.

Males are slimmer than females, but both are equipped with long legs, where the first / last pair is much longer than the second / third, which allows the spider to move rapidly.

What is "Yellow Spider"

It feeds on other, smaller spiders, and also eats small insects, as well as their eggs. But if there is not enough food, the yellow-eyed spider turns into a cannibal and eats its eggs. This, however, is most often done by the male yellow eyed spiders, who often come to blows with the females trying to keep their eggs until the little spiders hatch.

The yellow-eyed spider hunts at night and prefers to seek out its prey rather than wait patiently for it to fall into one of its webs. When it finds an insect or a smaller spider, the yellow-eyed spider lunges at its prey, grabs its legs and tentacles that are in front of it, and bites it. The second neurotoxic poison paralyzes the victim or may even kill him. The Yellow Spider must drink the victim's vital juices and then immediately sets out to look for a new one.

An ignorant person can easily confuse a house spider with a stray (biting) spider that is extremely similar to it, representing a certain danger: its bite provokes the appearance of a slowly healing ulcer.

Tegenaria is not able to bite through the skin, and its poison is not so strong as to seriously harm the human body.

spreading yellow hot spider

The number of yellow-eyed spiders in residential buildings increases in autumn when it gets cooler and they look for a place to find more food. In early summer, male yellow-haired spiders begin chasing females and mating with as many people as possible. Females mate only once and their bodies produce 5 white egg sacs, each containing about 40 eggs. A woman hides bags in places that are hard to see - behind cabinets and paintings, in closets and in corners. The female yellowtail spider often holds egg sacs and may bite if they feel threatened.

Range, distribution

Tegenaria Domestica lives everywhere, with a small caveat - where people settled.

In the wild, these synanthropic spiders are practically not found. Those rare specimens whom fate has thrown away from human habitation are forced to settle under fallen leaves, fallen trees or under their bark, in hollows or snags. There, house spiders also weave their large and insidious tube-like webs.

Interesting Facts About Spider Spider

When the little spiders appear, the female spider spider leaves the hiding place with them, but each of the spiders begins to lead a life of its own. The reason for this is the fact that the Yellowstone spider loves the smell of carbon monoxide in gasoline. Yellow sponge bags in car pipes create barriers that are at the same time a prerequisite for too high pressure gasoline and, in turn, can cause a fire.

An interesting fact is that it is considered less harmful to farmers because it kills most of the insects that destroy crops. The yellow-eyed spider often prefers to live in gardens and can be found among boards, firewood, stacks of leaves.

This is interesting! The behavior of the house spider determines what the weather will be like. If he sits in the center of the web and does not come out, it will rain. If the spider has left the nest and builds new webs, it will be clear.

Lifestyle

The spider prefers to fix the woven trap in the dark corners of the house.. The nets are almost flat, but their center sharply goes into a corner, to where the hunter himself hid. The web does not have sticky properties: it is loose, which is why insects lose their ability to move and get stuck in it until the executioner arrives.

The yellow-eyed spider bites when it senses the proximity of a person or animal. The yellow-eyed spider often hides in piles of clothing, whether clean or dirty, and when someone takes or puts the clothes on, the spider bites. In order to protect themselves, people are forced to fill in all the small cracks, not only under and around, but also in the very doors of their houses. It is also recommended to block all miniature openings at the base of the house so that the yellow hot spider cannot enter the house. If there is a yellow-eyed spider in the house, we call pest control specialists who vacuum the smallest corner of the dwelling, then all the bags.

This usually happens at night when the males go in search of amorous adventures and food. By the way, males, unlike females, do not weave a web, since, like all vagrant spiders, they can hunt without it.

The web with the infested fly begins to shake, the spider runs out of the ambush and bites into the unfortunate with its hook-shaped jaws with poison.

During the scientific picnic of the Polish Radio and the Copernicus Science Center, spiders were the stand of the Podlasie Academy. The exhibits were dried by spiders, immersed in fixative and living fluids. Marek Labka from the Institute of Biology at Podlaskie University. How did the idea of ​​creating such unpopular animals become the hero of a science picnic?

What is terrible, dangerous, mythical - always attracts attention. main reason in that we want to show our work. We have created a scientific group to study this group of animals - their taxonomy, their ecology, their ecosystems. Is it difficult to popularize basic research?

This is interesting! The house spider is not interested in stationary objects, so it sits next to the victim for a long time (throwing a pedipalp or a walking leg on it) waiting for movement. To make the insect move, tegenaria starts kicking the web. As soon as the prey startled, the spider drags it into the lair.

The spider is unable to devour prey - it has a very small mouth and no chewing jaws that grind food. The villain waits for the insect to reach the desired condition under the influence of the injected toxin in order to suck out the contents.

Basic research is very important because it allows us to understand the role that different kinds play in ecosystems. This knowledge is very practical - some animals are important as a bioindicator because they tell us what the condition is. environment. By introducing animals that most of us don't like, should we convince them or warn them of the threats?

We have a collection of living representatives of Polish species common spiders. There are also two species of South American birds and individuals from Australia and New Guinea - selected for their size, venom toxicity. Poisonous animals attract spectators. It's good to know that spiders are not poisonous because they are so black. This is their way of surviving in extremely difficult conditions. Some live in the desert, where for many days they cannot meet any living being. In the event of a meeting, they must have a guarantee of the effectiveness of their weapons.


As soon as the spider has begun to eat, other insects crawling by cease to exist for him. The explanation is simple - Tegenaria Domestica does not know how (like many spiders) to wrap food in reserve, putting it aside.

In addition to flies and fruit flies (drosophila), these spiders, like all predatory arachnids, can eat any living food that is suitable in size, such as larvae and mealybugs. It is believed that the house spider is useful, as it destroys harmful insects, including house flies.

A bird bite can be dangerous. Can his Italian hurt us? When the monkey is disturbed by it, it shakes them out of the abdomen to pierce the skin of the tormentor, causing irritation. Breeding such spiders is becoming fashionable. People buy them, not always from legitimate sources, and then take pictures of the spider on their face or in their hand.

You can also raise house spiders which are also attractive. Of the more than 800 species, only a few can bite painfully, but it is not a very toxic venom. Most Polish spiders cannot even pierce human skin, so there is nothing to be afraid of. Spiders have lived on earth for 400 million years. We as a species have lived for several tens of thousands of years. It's easy to conclude that spiders don't exist to attack humans. If we go to the parade, we will disturb their environment, there may be bites.
