How long does it take for a spider to die, and can a spider be killed?

Different varieties determine the lifespan.

Spiders can be killed. Folk legends, such as the discovery of spiders at home, indicate that the happy event is approaching, should be carefully invited out, not killed, but this is only a superstitious statement, not credible. Although spiders can eliminate mosquitoes, flies, moths and other pests in the home, some spiders are poisonous and most people cannot distinguish between them, so it is necessary to clean them up for safety.

According to the literature, there are 3,821 genera and 42,055 species of spiders in the world (2010), and about 3,800 species in China, belonging to 67 families. There are a total of 14 orders in the Arachnida, 5 of which have been extinct, and 7 orders have been discovered in China.

Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them. Crab spiders wait for their prey on flowers that are similar to their body color.

Spiders burrowing in the earth build burrows lined with silk, and the entrance of the burrow has a trap that opens at night to prey on insects that pass through the hole. funnel spiders weave funnel webs, and insects fall into the nets to cause vibration; The spider itself resides in a filament tube with a narrow end that leads into a plant or a crevice in a rock.

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.
