How many spiders do you give birth to in a litter? How long can a spider live

Some females mate only once, while others mate with multiple males in succession, and after mating, the female lays a single egg bag containing several to a thousand eggs, or several egg sacks, which contain fewer eggs than one time.

A female spider generally lays only one egg bag, but also lays multiple egg bags, such as 5 6 garden spiders, 13 red spotted spiders, and the number of eggs laid by a female spider can range from a few to hundreds, such as 60 720 red spotted spiders, and 1000 species of garden spiders.

In terms of living and predation methods, it can be roughly divided into: web-forming spiders and wandering spiders. The most important characteristic of a web-forming spider is its web-forming behavior.

Spiders secrete mucus through protrusions at the tips of silk sacs, which can congagulate into very thin filaments when exposed to air. Webs made of silk are highly sticky and are the main means of predation for spiders. For insects that stick to the net, spiders will first inject a special liquid jujube digestive enzyme into the prey.

This digestive enzyme causes insects to stun, convuls, and die, and liquefies their bodies, which feed spiders by sucking. Spiders are oviparous, and most male spiders are devoured by female spiders after mating with female spiders, becoming food for female spiders. The wandering spider does not build a web, but wanders around or camouflages on the spot to prey on the prey before the spider reaches maturity, as it grows, it must go through multiple molts, and the number of molts and the interval are very inconsistent, generally speaking, small spiders molt 4 or 5 times in their lifetime; medium-sized spiders about 7 to 8 times; Large spiders are about 11 13 times, such as the male spider of the red spotted venomous spider molts 5 times and the female spider 7 times.

Compared to ordinary insects, spiders are long-lived, most spiders complete a life cycle, generally 8 months to 2 years, and male spiders are short-lived and die soon after mating. Others such as water spiders and cunning spiders can live for 18 months, burrowing tarantulas can live for 2 years, cancer spiders can live for more than 2 years, and birdcatcher spiders.

The lifespan is up to 20 to 30 years.

Spiders vary greatly in their species and reproduction methods, so the number of spiders in a litter also varies greatly. In general, spiders are hermaphroditic and can undergo autofertilization, and the number of eggs in the spawning pouch can vary greatly, from 20-30 to hundreds.

In the case of the Australian redback spider, the female spider lays 20-30 eggs at a time, and the hatching period is about 20 days. Young spiders feed on their mothers, so red-backed spiders lay a large number of eggs to ensure that their offspring have enough to eat.

In summary, the number of spiders in a litter varies depending on the species and mode of reproduction, ranging from 20-30 in the smallest to hundreds in the large.

A common spider can live from 8 months to 2 years, and a bird-catching spider can live up to 20 to 30 years.

The lifespan of different types of spiders is also unequal, ordinary spiders may live for more than ten months, and male spiders are short-lived, and they will die not long after mating. Burrowing spiders can live for more than two years, cancer spiders can live for more than 2 years, and birdcatcher spiders can live for up to 20 to 30 years

Spiders are arthropods with a body length of 1 90 mm, and the lifespan of spiders depends on the environment in which they are raised, as well as the relevant feeding methods. For example, the humidity of raising Chilean red roses should be low, suitable for about 40-60%, and the maximum humidity should not exceed 70%. Their optimal temperature is around 25-27 and can be lowered by about 3-5 at night.

In winter, electric felts can be used for heating, while in summer there is no need for any insulation.

The habits of spiders

Spiders are diverse, widely distributed, adaptable, and can live or build webs on the surface of the soil, in the soil, on trees, among grasses, under rocks, in burrows, at the water's edge, in low-lying areas, in bushes, moss, inside and outside houses, or in freshwater, coastal lake zones. In other words, traces of spiders can be found in water, land, and air.

Spiders mostly feed on insects, other spiders, and myriapods, and some spiders also feed on small animals. They can potentially capture prey within 30 centimeters and pounce violently towards it. Many spiders use the fewest silk to weave the largest webs, which act like air filters, trapping and feeding on insects that are invisible, not very flying, and finally feed themselves.

A spider generally lives for 8 to 24 months.

Spiders are long-lived in the insect kingdom, with males having a short-lived life and dying soon after mating. The lifespan of spiders also varies depending on the species, such as water spiders and cunning spiders can live for 18 months, burrowing tarantulas can live for 2 years, cancer spiders can live for more than 2 years, and birdcatcher spiders can live up to 20 to 30 years.

Male spiders are willing to sacrifice themselves to be eaten by females after mating, and although this is uncommon, it can cause the male spiders to have a drastic reduction in lifespan, and all this is due to the instinct of the spring generation after breeding.

Take the male redback spider as an example, after the male spider matures, he does not eat or drink, and only relies on the energy stored before to sustain life, and cannot withstand the torture of long journeys at all. Skinny redback males have a hard time taking risks once they leave their own webs. Eventually, only 20% of males are able to reach the female's webs for a chance to mate.

Spider habits.

Spiders usually live in dark and damp environments, and they are photophobic, so a dark environment is more suitable for them. Spiders have a mixed diet, often eating some myriapods, insects and other spiders, and are also very resistant to hunger, and their temperament is also very fierce, and they will kill each other. They have a strong sense of territory, so they are usually raised separately when they are bred in captivity.

There are about 40,000 species of spiders in the world, and they are found everywhere except Antarctica. Some of them have ugly appearances, some are faltering, and some can walk and jump well, which can be described as strange.

zhe has to study it. 10,000 species 1,000 spiders.

Spiders like dark and damp, ventilated and breathable places burrowing, suitable for temperature 10 35, humidity 50% 80% of the environment, adult spiders once mated, lifelong egg-laying, 3 June for the oviposition period, the peak period can be laid three times every two years, the average egg-laying 100-300, the birth period of 15 years, egg survival rate of 95%, life span 30 years.
