Some spiders live for just a few months—others can outlive your pet dog. Surprised? I was too. Whether you’re a spider enthusiast or just curious about that eight-legged roommate in your shed, this guide ranks 26 common spider species by lifespan. From decade-long burrowers to fast-living hunters, you’ll find out how long each one lives—and what their life cycle looks like.
1. Tarantula Lifespan
Tarantulas are large, ground-dwelling spiders known for their impressive size, hairy bodies, and long life—especially in captivity. These spiders are slow-growing, and their lifespan varies greatly between males and females. They are commonly found in warm climates across the Americas, Africa, Asia, and Australia. Here are the 16 Types of Common tarantulas.
Lifespan
Tarantulas have one of the longest lifespans among all spider species.
- Female Tarantulas can live between 15 to 25 years, and in some cases, even longer. Their longevity is due to slower maturation and extended adult life after reaching sexual maturity. Females continue to molt even in adulthood, which contributes to their extended life.
- Male Tarantulas, on the other hand, typically live only 3 to 6 years. Once they reach sexual maturity (usually after 2–5 years), they stop molting and die shortly after mating or from natural decline.
This stark contrast in lifespan is common in many spider species, but it is especially pronounced in tarantulas.
Life Stages
Egg Stage:
The female lays 50 to 200+ eggs in a silk sac and guards it for about 6 to 9 weeks until the spiderlings hatch.
Spiderling Stage:
Freshly hatched spiderlings stay near the egg sac briefly, then disperse to live independently after their first molt.
Juvenile/Subadult Stage:
During this stage, they molt multiple times as they grow. This phase can last several years for females.
Adult Stage:
Males live a short time after maturity, while females may continue to molt and reproduce for decades.
2. Trapdoor Spider Lifespan
Trapdoor spiders are burrow-dwelling arachnids known for their camouflaged trapdoor-style burrows. They are slow-growing and have surprisingly long lifespans, especially among females.
Lifespan
Trapdoor spiders are among the longest-living spiders in the wild.
- Female Trapdoor Spiders typically live 10 to 20 years, and in some rare cases, even longer. They spend most of their lives inside the same burrow, venturing out only to catch prey or mate.
- Male Trapdoor Spiders usually live 5 to 7 years. After reaching maturity, they leave their burrows in search of females, mate once, and then die shortly after.
Their sedentary lifestyle contributes to their longevity, especially in stable, undisturbed environments.
Life Stages
Egg Stage:
The female lays her eggs in a silk sac inside the burrow, where they stay safe for 6 to 8 weeks before hatching.
Spiderling Stage:
Spiderlings stay inside the mother’s burrow for a short time, then leave to dig their own small burrows.
Juvenile/Subadult Stage:
They remain hidden in burrows, molting and growing slowly over several years.
Adult Stage:
Mature females continue life in their original burrow. Males leave to mate and typically die soon afterward.
3. Mouse Spider Lifespan
Mouse spiders are robust, ground-dwelling spiders native to Australia, known for their powerful fangs and burrow-based lifestyle.
Lifespan
Mouse spiders are long-living compared to many other species.
- Female Mouse Spiders live around 10 to 15 years. They remain inside their burrows for nearly their entire lives and are rarely seen.
- Male Mouse Spiders live about 3 to 5 years, dying shortly after reaching maturity and mating.
Their long life is closely tied to their stable underground habitats and minimal movement.
Life Stages
Egg Stage:
Eggs are laid in a silk sac and kept in the burrow until hatching, usually in 6 to 7 weeks.
Spiderling Stage:
The young remain briefly in the burrow before dispersing to build their own shallow tunnels.
Juvenile/Subadult Stage:
They grow slowly in their own burrows, molting several times over a period of years.
Adult Stage:
Females rarely leave their burrows. Males mature, search for a mate, and typically die soon after mating.
4. Wolf Spider Lifespan
Wolf spiders are fast, ground-dwelling hunters found across the globe. Unlike web-building spiders, they actively chase and pounce on prey. They’re also known for their excellent vision and maternal care.
Lifespan
Wolf spiders have a moderate lifespan among spiders.
- Female Wolf Spiders generally live 1 to 3 years. They often survive through one or two breeding seasons and can live longer in captivity.
- Male Wolf Spiders live about 1 year or less, typically dying soon after reaching maturity and mating.
Their active, above-ground lifestyle exposes them to more predators and environmental threats, which can shorten their life expectancy in the wild.
Life Stages
Egg Stage:
The female carries the egg sac attached to her spinnerets for about 2 to 3 weeks, protecting it from damage and predators.
Spiderling Stage:
Once hatched, spiderlings climb onto the mother’s back and stay there for about a week before dispersing into the environment.
Juvenile/Subadult Stage:
They grow through multiple molts over several months, developing stronger legs and better hunting abilities.
Adult Stage:
Once mature, males leave their habitat in search of females and die after mating. Females continue hunting and may reproduce again.
5. Fishing Spider Lifespan
Fishing spiders are semi-aquatic hunters often found near ponds, streams, and wetlands. They can walk on water and even dive to catch prey like tadpoles and small fish.
Lifespan
Fishing spiders live relatively short lives but slightly longer than many typical house spiders.
- Female Fishing Spiders can live 2 to 3 years, depending on species and environmental conditions.
- Male Fishing Spiders live about 1 to 2 years, usually dying soon after mating.
Their habitat and predatory style expose them to both aquatic and terrestrial dangers, impacting survival rates.
Life Stages
Egg Stage:
The female carries her egg sac in her jaws and guards it carefully for about 2 weeks until the spiderlings emerge.
Spiderling Stage:
After hatching, spiderlings ride on the mother’s back briefly, then disperse to hunt on their own.
Juvenile/Subadult Stage:
They molt several times over months, gradually growing into strong, agile hunters that stalk prey along water edges.
Adult Stage:
Mature males die soon after mating. Females continue to hunt near water and may lay multiple egg sacs during their lifetime.
