An ordinary spider in an apartment. How long do spiders live? Lifespan of different types of spiders

How long ordinary spiders live depends on their type, in total, experts number 42 thousand. Arthropods inhabited almost all continents the globe are found everywhere. live in a person's house as a pet, and some representatives of a huge family settle there without asking. The life expectancy of domestic spiders is longer than wild ones.

How long do ordinary spiders live in nature

Small habitual spiders according to various data in conditions wildlife live from 10 to 12 months. The lifespan of the female is always longer than the male. Males rarely die of natural causes, as they are eaten by hungry females almost immediately after fertilization.

Theoretical figures do not always agree with the real ones. In nature, small spiders have many natural enemies from which you have to hide from day to day. Spiders that live in Russia often die from adverse weather conditions, poison, hunger.

Interesting!
One of the brightest -. It lives in the wild, weaves large trapping nets, feeds on insects. Can bite a person, saving own life. How many years the cross spiders live depends on the gender. Males die immediately after mating, females - after the formation of a cocoon, the deposition of eggs. The life expectancy of males is no more than 3 months, female - 6.

How long do house spiders live

Arthropods enter human habitation through open windows, doors, cracks in the wall. They settle in the corners of the rooms, behind the furniture. During the day they hide from the sun's rays, at night weave a web, hunt. They eat house flies, fruit flies, mosquitoes, cockroaches.

At home, the spider can live up to 1 year, favorable conditions contribute to this. climatic conditions, lack of natural enemies. However, often life stops due to lack of food, from the hand or broom of a person.

Interesting!
They often gather on the walls of the house, sitting motionless until the evening. As darkness falls, they become active. They are not dangerous for humans. How spiders live in the wild is well known - they hunt small insects, grasshoppers, even locusts. The life expectancy of the female is no more than 4 months, the males die earlier.

Spiders are all around us. Therefore, it is important to know which spiders are safe and which ones should be avoided.

Spiders are one of the oldest inhabitants of the planet, known from the Devonian and Carboniferous periods. It is believed that they appeared about 400 million years ago. creations Paleozoic era had a characteristic arachnoid apparatus, but were more primitive. Their habitat is the widest - the entire planet, not counting the Antarctic.

Spider science: what is it called?

Araneology is the science of spiders, which is part of the branch of zoology - arachnology. Arachnology is the study of arthropods, invertebrates, arachnids. The origin of the name is ancient Greek.

Also, arachnology is the art of weather prediction based on observing the actions of spiders.

Spiders - what are: types

Researchers know about 42 thousand species of spiders. Spiders can be divided into three large suborders, which mainly differ in the structure of the jaws, more precisely, in the position of the chelicera relative to the longitudinal axis of the body.

Suborder Orthognatha

More often, representatives of this suborder are called migalomorphs. Characterized by the presence of dense hairs, large sizes and the primitive structure of the jaws - the claw is directed downward and grows only on the upper jaw. Respiratory system represented by lung sacs.

Most migalomorphs live in warm climates. Burrows suit themselves underground.

Orthognatha include:

tarantulas
funnel spiders
ctenizides
spiders - diggers

Suborder Araneomorpha

Almost all other spider species known to naturalists belong to the large Labidognatha or Araneomorpha group. They differ in that they have claws equipped with both jaws. The respiratory system is represented by the trachea.

Types of spiders that catch prey without a net:

crab spiders
jumping spiders
wolf spiders

Types of spiders using a trapping web:

linifid spiders
web spiders
funnel spiders, or brownies
centipede spiders
orb weaving spiders

Among the araneomorphic spiders, there are also those that are not able to produce cribellum - the substance from which spiders produce durable spider silk, and those who produce it.

Suborder Mesothelae

Lyphistiomorphic spiders are distinguished by the fact that the chelicerae are spaced to the side, and not directed downwards. This position is considered more evolutionarily advanced. But, this suborder is considered the most primitive, its traces were found in carbon deposits. Spiders have archaic lung sacs, four pairs of arachnoid warts that have not yet been shifted to the end of the abdomen. They live in earthen burrows that are closed with a lid. Signal threads diverge from minks. Although one species prefers caves, where it makes spider tubes on the walls.

These include:

arthropod spiders
primitive arthrolycosid spiders
primitive spiders arthromygalides

Spider: insect, animal or not?

Spiders belong to a type of animal - an order of arthropods in the arachnid class. Therefore, spiders are animals, not insects.

Differences between a spider and an insect:

Spiders have four pairs of legs, and insects have three pairs.
spiders do not have antennae characteristic of insects
many eyes, up to twelve pairs
the body of a spider always consists of a cephalothorax and an abdomen
some types of spiders have intelligence: they distinguish strangers from their own, can protect the owner, feel the mood of the owner, even dance to the music. Not a single insect can do this, unlike an animal.

Spider body structure

The body of spiders, covered with an outer skeleton of chitin, consists of two sections, which are connected by a small tube:

the cephalothorax is formed by the head merged with the chest
abdomen

cephalothorax

The cephalothorax is divided by a groove into two sections: head and chest. In the anterior head section are the eyes and jaws - chelicerae. In most spiders, the chelicerae are directed downwards, ending in a claw. The claws contain venom glands.
The lower part of the jaws - pedipalps, are used as palps and grasping elements. Between the pedipalps is a mouth that serves for sucking. In some mature males, the pedipalps are also cymbium - the copulatory apparatus.
Simple eyes are also found in the anterior head region.
Four pairs of jointed legs are also located on the cephalothorax in the thoracic region. Each spider leg consists of 7 segments. The last segment of each leg has two or more smooth or serrated claws.

Abdomen

The abdomen can have a shape: round, oval with processes, angular, elongated worm-shaped. On the abdomen are stigmas - breathing holes.
On the underside of the abdomen there are arachnoid warts, which contain spider glands. Near the base of the abdomen is the genital opening. In females, it is surrounded by a thickened chitinous plate, while in males, the genital opening looks like a simple gap.

Spiders can grow up to 10 cm in size, and their limb span can exceed 25 cm, it all depends on the species. The smallest representatives are only 0.4 mm in size.

Color, pattern depends on the structure of the scales and hairs covering the body, the presence of pigment and the type of spider.

How many legs does a spider have?

All spiders have four pairs of legs, which are located on the cephalothorax and are usually covered with hairs.
Each foot has crescent-shaped, comb-like claws. Between the claws, most often, there is a sticky pad - a claw-like appendage.
Web-weaving spiders have auxiliary serrated claws that allow the spider to move freely along the web.

How many eyes does a spider have?

Depends on the type. Some species have only two eyes, and some have up to twelve. Most species have 8 eyes, which are arranged in two rows.
In any case, the two front eyes are the main (master). They differ in structure from other side eyes: they have muscles to move the retina and do not have a reflective shell. Also auxiliary eyes are distinguished by the presence of light-sensitive retinal cells. The more of them, the sharper the spider's vision.
Some spiders can see as well as humans and distinguish colors. For example, jumping spiders. Night hunters, for example, sidewalker spiders, see perfectly not only at night, but also during the day. But wandering spiders see best.

How does a spider spin its web?

The thread of the web consists of many thin threads that the spider glues together with a special liquid that quickly hardens in air. Thanks to this, such a high strength of the web is achieved that spiders even travel with it, overcoming kilometers of distance.

The web can be dry, sticky, elastic - it all depends on the purpose of the thread.

Types of threads for cobwebs:

for cocoon
sticky thread
for moving
to confuse prey
thread for fastening

The design of the web depends on the method of hunting. Spiders use a thread that reflects ultra-violet rays that most insects see. Moreover, the spider weaves ultraviolet-reflecting threads in such a way that they look like flowers, which also reflect ultraviolet. Therefore, insects fly to the alluring and sweet flower, and fall into the web.

Stages of weaving a web:

The first spider releases a long thread. This thread is picked up air flow, rushes to the nearest branch and clings to it (Fig. 1, 2).
Then another free-hanging thread parallel to the previous one is woven. The spider moves to the middle of this thread, which is stretched under its weight, and weaves another thread in a downward direction until it finds the third support (Fig. 3).
On the support, the spider fastens the thread and a Y-shaped frame is obtained.
Next, a general contour is woven and a few more radii (Fig. 4).
At these radii, an auxiliary spiral is woven (Fig. 5). This whole frame is woven from a non-sticky thread.
Next, the spider weaves a second spiral with a sticky thread, towards the middle of the web from its edge.

Construction may take 1-2 hours.

How do spiders reproduce?

Males usually differ from females in size (the male is smaller), long legs, brighter coloration, the presence of pedipalps, which appear in males only during the last molt.
First, the males weave a special sperm web. Although some species are limited to a few stretched threads. Then the spider puts a drop of sperm on the web and fills the pedipalps with sperm, with the help of which it injects the sperm into the female's seminal receptacle. And goes in search of a female.
The spider finds the female by smell. Having found a suitable female, the male begins to cautiously approach. If the female is not disposed to courtship, then she attacks the spider, and may even eat it.
If the female looks at the male favorably, then the male begins to lure the female: he performs “wedding dances”, “tinkles” his feet, and brings prey. Having appeased the female, the spider carefully approaches her, touches her with the tips of her legs, then with her pedipalps and retreats. Also, the male "drums" on the substrate.
If the female does not show aggression and "drums" herself, then the male carefully approaches and brings his pedipalps to the female's genital opening. The act lasts a few seconds.
The male then runs away to avoid being eaten by the female. Although this happens quite rarely. A female can have several males in one season.
After 6-10 weeks, the female spins a cocoon, in which she lays up to 500 eggs. The female carefully guards the cocoon, holding it between the chelicerae. After another 5 weeks, spiders appear.

How long do spiders live?

Most spiders live for a year. But some species, such as Grammostol pulchra from tarantulas, can live 35 years. And this applies only to females, males even tarantulas live 2-3 years.

Non-poisonous spiders: a list with names

Nothing like poisonous spiders does not exist. Poison is necessary in order to paralyze the victim, for protection.

But the venom of most spiders encountered is not dangerous. In some cases, it is so small that no one will notice, or redness and swelling will appear. Although in isolated cases, an allergy to spider venom is possible.

Safe for humanscommonspiders:

Common Harvester Spider. The size of the male is up to 7 mm, the female is up to 9 mm. Leggy. They hunt in the dark. They like to gather in a pile so that they seem to be a tuft of wool. Weaves a non-sticky web. They scare off enemies with the release of an unpleasant odor.

More than 5 thousand species. This is a small 5-6 mm spider that loves to bask in the sun and climbs glass perfectly. good jumpers, can jump to a distance of up to 20 cm. Webs do not weave, they attack by jumping, they have excellent eyesight.

More than 1 thousand species. Size up to 25 mm - females, up to 10 mm - males. It has several white spots on its abdomen, forming a cross. Hunt with a round trapping net which can be up to 1.5 meters in diameter.

Size up to 10 mm. Hunts from an ambush, instantly grabs the victim and paralyzes her with poison. Networks do not weave. It has camouflage - if necessary, changes color from rich yellow to white. Those that hunt on the bark of trees are brown, and those in the leaves are variegated.

House spider or funnel spider, the most famous and widespread. Weaves a web in a secluded place: on the ceiling, in the corner, behind the closet. The male is up to 10 mm in size, the female is slightly larger - up to 12 mm. The color is yellow-gray with brown spots.

The size of the female is up to 10 mm, the male is slightly smaller. The color is light yellow, sometimes greenish. On the underside of the belly, elongated in the form of a seed, there are two light stripes. They build circular networks with large "holes" designed for centipede mosquitoes. The web is built near water, they know how to run on water.

The size of the male is up to 16 mm, the female is up to 12 mm. A rare spider, adapted to live in freshwater sluggish water. Can swim. The abdomen is covered with hairs to hold air, so under water the spider appears "silver". A “bell” filled with air spins in the water, where it lives: rests, leaves reserves, eats caught prey.

Spider-tarantula (tarantula). Large, up to 20 cm with a leg span. They have a beautiful variety of colors. Weave a web. Some species are completely harmless to humans; others may cause swelling, redness, itching, fever, and muscle cramps from the bite of others. Fatalities not described. It is they who are most often kept in homes, females of some species live up to 35 years. Very unpretentious in care. Bird-eaters can even be trained.

Top 10 most dangerous, poisonous, deadly spiders in the world, on the planet: a list with names

A resident of the tropics and subtropics of South America is the most dangerous spider according to the Guinness book. The size of the spider is 10-12.5 cm. It is fast, active, does not spin webs, and constantly moves in search of prey. Likes bananas. It feeds on other spiders, insects, lizards, birds.

In danger, it rears up, shows fangs. Deadly poison for weakened people, children. Without assistance, death from the bite of some individuals can occur in 20-30 minutes. In an adult healthy person a severe allergic reaction usually occurs.

The habitat is the deserts of South America, Africa. They can go without water and food for a long time - up to a year. Size taking into account the span of the paws up to 5cm.

When hunting, it burrows into the sand, lets it get closer and attacks from cover. The poison is a hemolytic-necrotic toxin that thins the blood and causes tissue decomposition. The victim dies from internal bleeding. No antidote has been created, but people die extremely rarely.

Habitat - Australia, within a radius of 100 km from Sydney. Size - up to 5 cm. Lives and hunts in stumps, under stones, on trees or open areas. The venom is harmless to most mammals, but deadly to humans and primates.

The spider, in danger, rears up, shows fangs. When bitten, it digs into the body of the victim and bites many times in a row. At the same time, it is difficult to tear it off. Poison is dangerous due to large doses. First, the state of health worsens: nausea, vomiting, sweating. Then - blood pressure decreases and blood circulation is disturbed, and in the end - the respiratory organs fail.

One of the most known species. Habitat - Mexico, USA, southern Canada, New Zealand. They prefer to live in the desert and prairies. The size of the female is up to 1 cm. Females are more dangerous than males. If bitten by a female, then the antidote must be administered within 30 seconds.

Spider venom x15 stronger than poison rattlesnake. The bite site heals up to 3 months. The bite is characterized by acute pain, which after 1 hour spreads throughout the body, causing convulsions. Difficulty breathing, vomiting, sweating, headache, paresthesia of limbs, fever.

It looks like a black widow. Originally lived in Australia, now spread throughout the world, with the exception of the poles. Up to 1 cm in size. It feeds on insects, flies, cockroaches, even lizards.

The poison is not able to kill a person, but after a bite, pain, cramps, nausea, increased sweating, and general weakness are felt.

6. Karakurt - "black worm"

From the genus of black widows, lives in the steppe and desert zones of Russia. The size of the male is up to 0.7 cm, the female is up to 2 cm. The most dangerous is the poison of females with red dots on their abdomen.

The bite of the spider itself is practically not felt, but after a few minutes, a sharp pain is felt, gradually spreading throughout the body. Convulsions begin, a red rash appears, the victim may feel causeless fear, depression. Without assistance, a bite can become fatal for 5 days.

The second name is violin spider. Habitat - northern Mexico, southern USA, California. Sizes of males - 0.6 cm, females - up to 20 cm. Not aggressive. Lives in dark, dry places: attics, sheds, closets.

The bite is almost insensitive. After a bite, the effect of the poison begins to be felt after it spreads throughout the body, in a day. The temperature rises, nausea, rash, pain throughout the body, tissue swelling appear. Tissue necrosis begins in 30%, organs sometimes fail, and only a few deaths have been recorded.

Initially inhabited only South America (Chile), now also lives in North America, found in Europe and Australia. Lives in abandoned places: sheds, woodpile, attics. Feeds on insects and other spiders. Size including paws - up to 4 cm.

The bite is painful, similar in strength to a cigarette burn. The poison has a necrotic effect. The victim feels severe pain. Renal failure may develop. Treatment takes many months, and 1 in 10 people die.

9 Wolf Spiders

Habitat - the whole world, except for Antarctica, but prefer warm countries. They live in bushes, in grassy meadows, in forests near water sources, in fallen leaves, under stones. Sizes - up to 30 mm. They feed on cicadas and bedbugs.

Bite tropical species can cause prolonged pain, dizziness, swelling, severe itching, nausea, rapid pulse. Their venom is not lethal.

Theraphosa Blond

10. Blonde Theraphosa

One of the largest spiders, the second name is the goliath tarantula. Body size - up to 9 cm, leg span - up to 25 cm. It feeds on toads, mice, small birds and snakes. It bites only in cases of danger.

The poison has a paralytic effect. But for a person it is fraught with only swelling and itching. When bitten by large animals and humans, venom is usually not injected. In case of danger, the tarantula shakes off sharp hairs from the back, which cause irritation of the mucous membranes.

Although dangerous spiders many, they rarely attack. Offense is usually associated with defense, and in ordinary life spiders shy away, preferring secluded places for life. There are few deaths, but care is always needed in handling these animals.

Video. The strangest spiders and unusual spiders in the world

Keeping spiders at home is becoming more and more popular today. Indeed, these are extremely interesting arthropods that do not require any complex care from the owner. In this article, we will talk about the lifespan of captive spiders, and also tell you about the factors that affect the age threshold of individuals.

Spider spider strife

Biologists know more than 42,000 species of arthropods. All arachnids known to scientists are different from each other. Some are microscopic in size, while others grow to truly gigantic proportions. The appearance of these spiders is varied, they differ in their behavior and life expectancy. So, for example, haymakers usually live no more than 6 months, managing to give several generations during this time. But all of us, well-known tarantulas, are able to live up to 15-17 years. Also centenarians include tarantulas and other large-sized arthropods.

If we talk about the factors that affect the life expectancy of spiders, we can note environment, the conditions in which these arthropods live, the absence of natural enemies, the appropriate food supply, etc.

How long do spiders live in natural conditions

The wild world is extremely cruel, so spiders in vivo rarely live to a ripe old age. They are threatened weather, numerous predators and lack of food. That is why it is often difficult for scientists who study these arthropods to accurately determine life expectancy.

Known only, what large species able to live much longer than small varieties. In arid regions, arachnids have a higher life expectancy than in tropical regions with humid climate. In the presence of an appropriate food base, the upper threshold of aging in individuals can increase significantly, so spiders that do not experience any problems finding food can live much longer than their starving counterparts.

How long will a house spider live

Pet arachnids will live much longer than their wild counterparts. This is due to the following factors:

creation of optimal conditions for life;
quality feeding;
lack of natural enemies.

Important! Life expectancy will largely depend on their proper feeding. Separate types can only feed on beetle larvae, which will need to be purchased from the appropriate pet stores.

Specific lifespan examples

As pets today, several dozen species of spiders have become widespread, which are of the greatest interest in keeping. Let's talk in more detail about how long arachnids live in captivity.

Keeping tarantulas, tarantulas and other arthropods at home is not particularly difficult. With the help of the simplest equipment in a glass container with spiders, you can maintain optimal indicators of humidity and temperature, and you can buy food for such pets in most large pet stores. All this will become the key to the trouble-free maintenance of arthropods, which will be able to live with you as long as possible without getting sick and without causing trouble.

Conclusion

Spiders are extremely interesting pets to keep., which differ in their size, behavior, appearance and life expectancy. Some species live no more than 3-6 months, while large arachnids, including tarantulas and tarantulas, can live up to 20-30 years.

- these are animals that since ancient times have caused both interest and fear in people. Each spider is interesting for its unique features of living, obtaining food, and reproduction.

In this article, we will cover these topics, consider the causes of the appearance of cobwebs in our homes and study effective ways breeding spiders.

A little about spiders

Today on our planet there is about 40 thousand species of spiders. Only a few of them live in Russia. For the most part, they live in open nature, but quite often they appear in people's homes.

In fact, only a few species can live indoors. Spiders and cobwebs in the house often scare people, and you should understand that these arthropods are not interested in people, they are afraid of them and will never attack first.

Tired of pest control?

Are there cockroaches, mice or other pests in the country house or in the apartment? They must be fought! They are carriers of serious diseases: salmonellosis, rabies.

Many summer residents are faced with pests that destroy crops and damage plants.

It has the following properties:

Gets rid of mosquitoes, cockroaches, rodents, ants, bedbugs
Safe for children and pets
Mains powered, no recharging required
No addictive effect in pests
Large area of action of the device

Black and white house spiders

The most common domestic spider species are:

haymaker, which has a small body and very long legs, reaching a length of 5 cm.
Gray house spider.
Tramp.
Black house spider. They live in the house and weave a tubular web in the corners, which is a serious trap for its victims. They are quite large in size, their length is about 13 mm. They bite a person extremely rarely, but if this happens, it is very unpleasant and painful, since it can cause such consequences as allergies, swelling, vomiting, dizziness and general malaise of the bitten.
white spiders there are various kinds, and live in various countries. So, for example, in the southern part of Russia, as well as in the countries of the Middle East, you can meet Karakut. Africa is home to the White Lady. In North America, southern Europe, Japan and Russia, it is found " flower spider» white. White spiders are rarely found in the house, they usually live in nature, in the garden, in the garden, in the forest, and their bite is the most dangerous for humans, and can even be fatal.

Many spider lovers keep them on purpose to add an exotic touch to their home, and they can also be classified as domestic. The most famous white spider among such pets is white-haired tarantula.

I regularly inspect my site, the result makes me very happy! I really liked that it works solar battery. I recommend the repeller to everyone."

What do spiders look like?

Each type of spider looks unique. Exotic spiders that live in terrariums tend to catch the eye with their impressive size, fleecy surface and bright colors.

Domestic spiders look more modest:

So, for example, a haymaker spider has a small body and very long legs, reaching a length of 5 cm.
Black spiders - black or dark gray, about 13 mm in size.
Gray spiders are very similar to black ones, having the same dimensions.
The tramp spider is brown and light brown in color, having an elongated abdomen and long legs.

Many types of spiders differ in their speed of movement, web, search for food, appearance, but the number of legs is the same for all - there are 8 of them.

The limbs of spiders differ in size and cover, but their main functions are inherent in all types of arthropods:

Legs are the means of transportation for spiders. Someone has the ability to move by jumping, someone uses lateral walking, someone runs on water, and some change locations by stomping loudly.
The limbs are carriers of many receptors: smell, touch, balance. They help spiders recognize danger, find food.
The function of the paws is to weave a web. Thanks to this ability, spiders have the opportunity to get food.
Spider parents with tentacles hold and move their cocoon to another place. It is for these purposes that spiders have this a large number of limbs that simultaneously serve them as hands, nose, vision and even the so-called "sixth sense".

Stories from our readers!
"Always used fertilizer and top dressing in his garden. Neighbor said he soaks seeds with new fertilizer. Seedlings grow strong and strong.

Ordered, followed instructions. Great results! We did not expect this! We harvested a wonderful crop this year, now we will always use only this tool. I recommend trying."

Types of spiders in Russia

There are quite a few varieties of spiders in Russia, the most common among them are:

Serebryanka- this is the only species that lives on the water and under it. The habitat is swampy water bodies of Russia. Refers to poisonous spiders.
Spider-cross living in temperate climate, on grass and branches of bushes and trees. It has a cross-shaped pattern at the top of the abdomen. Not dangerous to humans.
South Russian tarantula- lives in the semi-desert and steppe regions of Russia, lives in burrows. It is a poisonous and dangerous species of spiders for humans.
house spiders living closely with a person and safe for him. Weave a web in the most inconspicuous corners of the room.
Spider knitter, which has the ability to disguise itself and become invisible. Refers to non-poisonous representatives of arachnids.
jumping spider- jumping small spider. It has the ability to climb glass and capture its prey without the help of a web.
H black widow (karakut)- the most dangerous type of spider for humans. Lives in the Astrakhan and Orenburg regions, as well as in the North Caucasus.

Are spiders insects or animals?

Many people are interested in this question, some people believe that spiders are insects, however, this is not so.

Spiders belong to the class Arachnida and belong to a species of animal, not insects, despite the incredible resemblance to the latter. Arachnids were born 300 million years before insects.

Both of these species formed separate classes that have clear differences:

Insects: have 6 legs, belong to the class of insects such as arthropods, for the most part they are omnivorous creatures. The main divisions of the structure of insects: head, chest, abdomen, wings.
Spiders have 8 legs, belong to the class of arachnids, the type of arthropods, are very selective in food, born hunters. It consists of only two sections - the abdomen, from which the paws grow, and the cephalothorax, on which the spider's oral apparatus is located. Has the ability to weave a web.

What do spiders eat?

Spiders, despite their small size, consume a large amount of food, however, they may not eat. for a long time- from a month to a year. An interesting fact is that in a year the mass of food eaten by spiders exceeds the amount of food consumed by all people in the world.

Each species of spider has its own ways of obtaining food:

Creating traps using web weaving. Caught prey is processed by digestive juice, corroding it from the inside, after which the spider swallows it.
Search for food by spitting out sticky saliva, which allows you to attract food to yourself.

What do spiders eat:

The main diet of both street and domestic spiders are insects. Spiders in a private house feed on flies, mosquitoes, crickets, butterflies, mealworms, cockroaches, grasshoppers, woodlice larvae. Read the answer to the question for more details.
Spiders living in burrows or on the surface of the soil love to feast on beetles, orthopterans, and even snails and earthworms.
Some species hunt at night. So, for example, the queen spider creates a trap for moths at night.
Exotic spiders, due to their impressive size, choose larger prey for themselves. So, tarantulas prefer to hunt frogs, lizards, other spiders, mice, and even small birds. And the Brazilian tarantula is able to catch and eat medium-sized snakes and snakes.
Spiders living on the water catch tadpoles, small fish or midges floating on the surface of the water with the help of a web.
Some spiders use vegetable world: pollen, plant leaves, cereal grains.

How do spiders give birth?

By nature, sexually mature males differ significantly from females in their small size, bright colors, and short life span. They are found in nature, as a rule, they are much rarer.

In some species of spiders, males are not found at all. It's believed that the female spider has the ability to develop eggs virgin, therefore, can breed offspring without even being fertilized.

The male independently fills the genitals with sperm and goes in search of the female. Some species of spiders bring a gift to the "lady of the heart" - an insect, as attention and approval by her. Males try their best to care so as not to be eaten by the female. They perform a wedding dance - the rhythmic movement of their paws along their own web.

Some types of spiders fight on the female's web, while others mate with males. Many males, in order to avoid the threat from the female, mate at the moment she has experienced a molt, while she is still helpless. Indeed, often a fertilized spider strives to eat its partner. Sometimes the male manages to escape.

Some types of spiders create families: they live in the same nest, raise offspring, share prey. There are cuckoo spiders that toss their cocoons into the nests of other relatives.

The female spider can breed at a time up to 200,000 children. Such incredibly large offspring can bring both large and very tiny species of spiders. Spider eggs go through two molts before reaching the adult stage.

An interesting fact is that spiders have the ability to independently cause their birth in the case of sick or weak offspring.

How long do spiders live?

The life expectancy of spiders depends primarily on their species. Most spiders have many enemies and rarely live to a natural death.

Spider lifespan:

So, some live only a couple of months, while others can live for several years. Moreover, about six months is spent on the egg stage.
The life cycle of males ends much faster than the cycle of spiders. Subject to comfortable living, males live only two years, but females can live up to ten years.

There are also such records:

Some female tarantulas can live for over twenty years.
Spiders of the genus Sicarius living in South America and Africa can live up to 15 years.
Some tarantulas can live twenty years.
It is clear that spider species that are pets of humans and live in captivity have a longer life. History knows cases when such spiders lived up to thirty years.

Are house spiders dangerous to humans?

All spiders are naturally venomous, but the dose of venom from domestic spiders is not significant for humans. Therefore, in case of a bite, which is extremely rare, you just need to treat this place with an antiseptic. They can be dangerous only for people suffering from arachnophobia (fear of arachnids).

There are benefits from several individuals living in an apartment, because they destroy insects, which, as a rule, cause discomfort and pose a danger to people. Of course, if spiders are found on every corner, this creates a feeling of aesthetic rejection and unsanitary conditions in the house, so they should be removed.

How to get rid of spiders in the house?

In order to completely forget about the spiders in your apartment, you must use the following measures to combat spiders:

Create a clean living environment. Spiders are very afraid of cleanliness, so regular and thorough cleaning of the premises can bring out such tenants. Particular attention should be paid to the most secluded corners: the back walls of furniture, the bottom of the beds, the ceiling and walls.
Use special preparations from spiders: aerosols, crayons, gels, as well as ultrasonic. Well proven such chemicals, like Butox-50, Tarax, Neoron.
