How long does a spider live?

In this brief guide, we will answer the query, “How long does a spider live?” We will also discuss the length of time spiders can live without food and the life cycle of spiders.

How long does a spider live?

A spider’s lifespan can range from a few months to a little over forty years according to the species. Different species of spiders have different lifespans. House spiders have some of the shortest life spans of any spider, with tarantulas having the longest.

This also has a lot to do with the fact that spiders suffer numerous threats that lower their chances of living to a ripe old age. Many animals consume spiders, their eggs, as well as their young ones. Birds, reptiles, mammals, and numerous arthropods, including other spiders, centipedes, scorpions, and even certain insects, feed directly on spiders.

Spiders have an average lifespan of around a year, however, this varies by species. Another factor that determines the lifespan of spiders is gender. Usually, females live longer lives than males. 

This could be due to genetic power, as female spiders are in charge of producing eggs and caring for their young. It could also be due to the fact that some spider species kill or devour their spouse after mating.

The lifespan of some of the common species of spiders are:

  • The typical barn funnel weaver can live for up to 7 years.
  • Black widow spiders live for up to 3 years.
  • Wolf spiders live for up to a year. Males survive for a year or less, whereas females might live for numerous breeding seasons.
  • Tarantulas live for up to 30 years.
  • A trapdoor spider can live to be 40 years old, which is the longest for any spider species.
  • The average lifespan of a house spider is 1 year.
  • The male Brown Tarantula lives an average of 10 years, while the females can live up to 35 years.

How long can spiders live without food?

The length of time spiders can go without food varies depending on the species. Usually, larger species of spiders live longer without food than smaller species, although they may last anywhere from 30-60 days without food in general. Even newborn spiders can go for nearly as long without nourishment as their adult counterparts. 

They have no set eating schedule and will eat whenever they are hungry or manage to catch something. Spiders are mostly carnivores, so their diet mostly consists of live or recently deceased prey.

The availability of water also determines the time they can go without eating. They may survive for extended periods if water is freely accessible. When there is food scarcity, female spiders may devour their young after they’ve hatched, and siblings may eat their newborn family members. Spiders may engage in cannibalism when they don’t have enough food.

What is the life cycle of spiders?

The life cycle of spiders consists of the following stages of development:

Eggs

The life cycle of a spider starts with an egg. Many species prefer to lay their eggs in peaceful, undisturbed sites, such as wall corners or floor joists. Depending on the type of spider, they may place in silken nests or inside tiny holes or tunnels. Teardrop-shaped sacs, similar to those found in house spiders, can be found in sheds, cellars, and attics.

Spiderlings

Spiderlings are spider larvae. At this stage of the spider’s life cycle, they appear to be miniature replicas of adults. Some species use silk strands to float on heated air currents, a process known as ballooning, to escape their siblings after hatching. In the instance of the grass spider, hundreds of spiderlings hatch from their eggs and roam around in search of food.

Adults 

Most spiders mature after a few months of hatching from their eggs. Some male spiders are born fully developed, while almost all female spiders require additional time to mature.

Spiderlings become adults after molting five to ten times. Most only live for roughly a year. A few species, such as female wolf spiders, can live for several years.  If the sperm produced as a result of mating between a female and male spider has not yet been used, it can be lost due to molting. This can be a problem if the male spiders are not nearby.
