How long do spiders live? Factors affecting the life span of spiders and specific examples


Most spiders live only a few months, as they have many enemies in the form of various predators, parasites and diseases that kill them long before their natural old age. How long do spiders live? Those lucky ones who manage to complete their life cycle live for about a year or more, depending on the species. An interesting fact is that the spiders, which were kept in captivity, demonstrate amazing longevity. Some female tarantulas, for example, can live for more than twenty years.

The lifespan of spiders depends on the species.

Some species of spiders may not reach maturity for several years. Spiders of the genus Sicarius from the desert in South America and Africa can live up to 15 years. Spiders, weaving a web, as a rule, do not live longer than three years, even under optimal environmental conditions.

How long do spiders live? Mostly about a year, with five or six months often spent on the egg stage. Nevertheless, some tarantulas can live as long as twenty years. Stories are known cases when individual representatives in captivity lived to thirty years. And tropical racing spiders live for about three months or less.

Spiders: habitat

Asking about where the spiders live, it is better to ask a question about where they do not live. They are able to live almost everywhere and that is why they are among the most diverse living beings in the world. The only place in the world where these frightening insects do not occur is Antarctica.

So nature has ordered - spiders could evolve to such an extent that they can do without water for a long time and live in a very dry and hot climate. They can survive in the harshest conditions imaginable. They get water from their food sources. These living creatures are considered terrestrial, as they almost always live on land. They can be found on trees, plants, in the grass and so on.

These are quite versatile organisms that can live anywhere. They know how to remain virtually unnoticed and merge well with their natural environment. Some species live along the shores of lakes, ponds and other bodies of water, not because they need water, this habitat provides them with the necessary shelter and food sources.

What do spiders need in a man's house?

Spiders need not so much - some free space and food. Despite the fact that they prefer more mess and clutter, they can still be found in clean and well-ventilated rooms. In the houses and apartments of people, spiders choose cooler and darker areas, most often these are the corners of the walls in the closets, closet, hallway, on the balcony, behind the cabinets, and so on.

The ideal habitat is the absence of wildlife, as bondage increases their lifespan. However, it depends on how they are taken care of. After all, a person can also pose a certain threat to home spiders.

The biggest spiders in the world

One of the world's largest spiders is the Brazilian Wandering Spider, with a paw span of 15 cm. It is not the largest spider in the world, but its poison is deadly. A worthy place among the giants is the so-called Camel Spider, with which the myth is related, as if it feeds on camels and even people. However, in reality it is not. It is also called a scorpion, because it looks like it on the outside. The camel spider is about 15 cm long. The Brazilian giant reddish-red tarantula is one of the largest in the world. The male spider is usually smaller than the female, which can have a leg span of up to 26 cm.

The rarest spider in the world is Hercules Baboon. This huge spider has a paw span of approximately 20 centimeters; however, since 1900, not a single representative of this species has been seen. Despite its name, Hercules does not eat baboons, insects have always been his favorite treat.

Columbian giant black tarantula can reach 23 cm. This awesome black spider has brownish hairs and reddish marks on its body. This seemingly extremely aggressive eater is completely harmless to humans.

How many lives the biggest spider in the world?

The list of “The Biggest Spiders in the World” is headed by Goliath Bird-eater. Judging by the name, this spider is large enough to feed on birds. Goliath's body length reaches 10 cm, and his powerful canines grow up to 2.5 cm. His bite is not fatal for humans, but severe pain, nausea and excessive sweating are guaranteed. Its distinguishing feature is a hissing sound, which it can produce with its paws.

How long do spiders live that belong to the goliath species? Males live an average of 9 years, while 14 years is the average age of the largest spider in the world. When answering the question of how many spiders live, an interesting pattern is discovered: on average, females live longer than their partners, for example, one of the most dangerous spiders on the planet, the Black Widow, lives for about 5 years. For obvious reasons, males live much less.

Spider spider strife

To date, scientists have discovered more than 42 thousand species of spiders. All of them are very different from each other: some grow to gigantic sizes, while others, on the contrary, are so small that they are barely visible with the naked eye. No less diverse is the appearance of spiders, which, to one degree or another, reflects the character and habits of these “terrible” creatures.

Naturally, depending on the species, how many spiders live varies. Ordinary tarantulas, for example, do not die of old age after 14-17 years, while the haymakers go to a better world after 4-5 months. In addition, the fundamental factor affecting the life span of spiders is the environment. Namely, the conditions in which they live.

Cruel World of Wildlife

To begin with, spiders rarely live to a great age in their natural environment. Here, their existence is threatened by predators, difficult weather conditions and lack of food. That is why it is so difficult for scientists to know how long spiders live in the wild. Especially when it comes to tiny representatives of this family who can die even from one strong gust of wind.

And, nevertheless, they still managed to find out some interesting facts. For example, it is authentically known that large spiders live much longer than small ones. The same rule applies to those arachnids that are found in arid regions - their upper threshold of aging is rather high compared with tropical inhabitants.

How long does the home spider live?

In the house of man lives two types of spiders. The first ones are those who have secretly made their way there, the second - brought directly by people as pets. And those and others often live much longer than their brothers living in the lap of nature.

This is due to the fact that in the habitable room they do not have multiple enemies. They do not have to fear that heavy rain or drought will destroy their home, leaving the poor fellows alone with the cruel world. That is why many spiders tend to settle next to a person. And some of them began to dwell entirely in the homes of people, since they would not live beyond a single day beyond its borders.

  • Cover all openings and cracks leading to the outside:
    1. Using putty, fill the large crevices in closed doors and windows.
    2. Seal openings for wires, cables, electrical components.
    3. Replace or repair torn mosquito nets on windows and doors.
    4. Cover the ventilation holes as well as the fireplace with a fine mosquito net.
  • Turn off outdoor lighting so as not to attract not only spiders, but also other pests that serve them as food.
  • Block interior lighting with blinds or thick curtains.
  • Plan a transition to sodium discharge lamps for lighting, since their yellow light is less attractive to insects, which means spiders with nothing to eat.
  • Get rid of climbing plants, bushes and trees growing very close to the house. Vegetation is a good place to hide the spiders, and if it needs heat, food, it will move from the vegetation through the cracks to your home.
  • Remove the area around the house: leaves, stones, mulch, where spiders love to hide.
  • Keep the house clean, because in a clean home a spider has much less room for shelter, which means it will be possible that it will not stay with you there, even if you sneak inside the house:
    1. Do not leave food residues around the house, as they attract other pests and insects, such as ants, and these in turn attract spiders.
    2. Vacuum regularly and do wet cleaning.
    3. Do not leave dirty dishes.
    4. Wipe tables and countertops regularly.
    5. To store food, use plastic containers with tight-fitting lids.

The lifespan of spiders in captivity

Requirements for keeping spiders at home are minimal. It is enough to feed animals 1-3 times a month, to water, to monitor cleanliness. Comfortable temperature for most types of 23-28 C, humidity 70-80%. In addition, they must be provided with adequate ventilation.

The life span of most species of spiders in captivity has not yet been established, since there is no extensive practical experience in this direction. But the general trend is that spiders living in and under the control of humans live longer compared to their natural habitat. In addition, at home, they show less aggressiveness. It is also a recognized fact that the female lives longer than the male of the same species, who dies for a maximum of 1 year after the last molt, but there are no such restrictions for the female.

Bird-eating spiders are a popular pet species. They are considered long-lived among relatives. Thus, the female, who was caught in Mexico City in 1935, lived as long as 28 years.

The lifespan of some spiders in captivity:

Brachypelma albopilosum or the white-haired spider tarantula, originally from South America, is distinguished by slowness, lack of aggressiveness. The life of males is about 3 years, females - about 12 years.

Horse spider (Salticidae) - short-lived species. No more than a year live in captivity, but their content does not cause any difficulties, and it is a pleasure to watch their behavior (especially during the marriage period).

The life span of the orb-web spiders with proper care in captivity may slightly exceed 2 years.

The Mexican red-legged tarantula attracts breeders with a large size, bright color, and calm disposition. The life span is about 30 years.

Spiders in the wild

Today, more than 42,000 species of spiders are known. They live in different regions, but are more common in areas with warm and humid climates.

It is known that large spiders, inhabitants of desert-shrub territories, are prone to slow growth and long life expectancy. Spiders, originally from tropical rainforests, grow quickly, but do not live long. In most cases, they do not live longer than 12 months.

The orb-web spider or horned spider (Gasteracantha cancriformi). The male dies 6–7 days after the fertilization of the female, unless it becomes her lunch. The female dies, laying eggs. Thus, the life span of this species is not at all great: in males - up to 3 months, in females - up to 1 year.

The life span of one of the most dangerous spiders in the world is the black widow: females are about 5 years old, males are less.

The Mexican red-legged tarantula lives for about 30 years.

Curly-haired tarantula - about 20 years.

The bird-goliath is one of the largest representatives of arachnids. The life of the male is on average 9 years, 14 years - the female.

Pecillottery regalis is another type of tarantula, live - 5 years old males, about 9 years old females.

Tarantulas in nature live to thirty years.
