Do you want to learn about the spiders found in Western Australia?
Before we begin, I want you to know that the list below is just a fraction of the spiders in Western Australia. Because of the sheer number of these arachnids, it would be impossible to cover them all. For example, some estimates claim there are over 50,000 kinds of spiders on the planet (and the list is still growing)!
With that being said, I did my best to develop a list of spiders that are MOST often seen and easily identified.
Here are the 20 MOST common SPIDERS found in Western Australia!
#1. Australian Golden Orbweaver
- Trichonephila edulis
- Females are about 40 mm (1.5 in) long. Males are around 7 mm (0.2 in) long.
- The body has a black-and-white pattern on the back; the underside is yellow, while the abdomen is gray to brown.
- The web is about 1 m (39 in) in diameter and protected on the sides by a strong “barrier” web.
There’s no reason to fear this spider in Western Australia.
It isn’t aggressive, and its venom isn’t dangerous to humans. The Australian Golden Orbweaver’s bite may cause mild local pain, numbness, and swelling, but it prefers running away than striking. If you are bitten, try putting some cortisone cream on the bite.
Australian Golden Orbweavers are primarily active during the day when they check their web for prey. When insects get stuck in their web, this spider approaches and adapts its attack according to the prey’s size. For example, the spider will grab small prey and wrap it in silk without biting it. However, it will bite larger insects, wait for the venom to neutralize the prey, and then wrap it in silk.
#2. Redback Spider
- Latrodectus hasselti
- Females have spherical black bodies with a visible red line and an hourglass-shaped red/orange streak on the lower abdomen. They are 10 mm (0.4 in) long.
- Males are 3-4 mm (0.12–0.16 in) long.
The Redback Spider is also known as the Australian Black Widow.
It can be found all over Western Australia and is highly venomous. Be careful at night because this spider is nocturnal and spends its days in small crevices.
Unfortunately, female Redback Spiders are known to live near or inside human dwellings because they prefer warm, sheltered locations. Its venom can harm humans, especially if a bite is left untreated. The most common symptoms are nausea, vomiting, headache, and agitation. Get help right away; antivenom is readily available.
#3. Bronze Hopper
- Helpis minitabunda
- Males are 10 mm (0.39 in) long, larger than females, 8 mm (0.31 in) long.
- This species’ front legs are particularly long, and its first set of eyes is very large.
Look for Bronze Hoppers in moist areas with plenty of foliage. These spiders in Western Australia are active mainly during the day when they hunt for small insects like flies.
They get their name from the way they hunt and catch prey. First, they track the insect and slowly move toward it to avoid being sighted. Then, once they’re within jumping distance, they attach a silk dragline to their perch and jump on the insect!
Like most jumping spiders, Bronze Hoppers are harmless to humans and rarely bite. Instead, they prefer to avoid any perceived threats, including us!
#4. Christmas Jewel Spider
- Austracantha minax
Also known as the Jewel Spider and the Christmas Spider.
- Females are 12 mm (0.47 in). Males are 5 mm (0.20 in).
- They are easily identified by their six distinctive spines on the abdomen.
- Their color is predominantly black with white, yellow, and orange patterns.
Christmas Jewel Spiders in Western Australia are almost always found in groups.
This social species is rarely found alone, unlike most other spiders. Look for their large aggregations of interconnecting orb webs, which can be unsettling to see!
This spider is not harmful to humans, although the large, sticky webs can be inconvenient for hikers and backpackers. They aren’t aggressive, and biting is their last resort if disturbed. Even though they are harmless, their bite can cause temporary redness, itching, and swelling.
#5. White Banded House Jumper
- Maratus griseus
- Adults are 4-5 mm (0.15-0.2 in).
- Males are blackish, brown, white, or grey.
- Females are more camouflaged with mottled patterns of white and brown.
White-banded House Jumpers are also called peacock spiders in Western Australia. This name comes from the vivid color patterns males have on their upper abdomens.
Their bodies are connected with a flexible appendage that allows them to raise their abdomen or wave it side to side. They also have lateral flaps on the abdomen, which they raise and display during courtship to attract the female. During courtship, males engage in a complex dance.
Interestingly, a female White-banded House Jumper can signal a male that she is not interested in mating. There are two benefits to this signal. First, the ritual “dance” attracts predators, which is dangerous for both males and females. Secondly, the male doesn’t have to waste energy on an uninterested female. If the male persists in dancing, even though given the sign, the female might try to attack and eat him. After all, dating is dangerous in the world of spiders. 🙂
#6. Eastern Bush Orbweaver
- Plebs eburnus
- Females grow up to 8 mm (0.31 in).
- Males reach 5 mm (0.20 in) long.
- This species has a U-shaped white marking with two white spots on the underside of the abdomen.
Look for Eastern Bush Orbweavers in scrub and tall grasses. Females construct a vertical web decorated with stabilimentum, thick strands of silk that help to attract prey. Their webs are no higher than two meters (6.5 feet) from the ground.
This species is active mainly at night and tends to hide in leafy retreats during the daylight hours. Therefore, it’s unlikely that you’ll come into contact with this species, but if you do, don’t worry! They aren’t aggressive toward humans and rarely resort to biting.
#7. Grey House Spider
- Badumna longinqua
- Females are 15 mm ( 0.60 in) long. Males are less than 11 mm (0.43 in) long.
- The body is covered with light-grey hairs and spot-like markings.
- The legs are purplish-brown, with hairs arranged into stripes on each leg.
The Grey House Spider in Western Australia prefers man-made structures.
This species is widely found in human habitats, such as the insides of houses, under furniture, and in window frames and walls.
Grey House Spiders eat ants, moths, wasps, bees, and cicadas. So, even though they might invade your home, they’re actually a good houseguest! They mostly feed during the night, stay hidden during the day, and don’t wander around households.
The only time you may see Grey House Spiders out and about is during the mating season. Males leave their webs searching for a female, venturing into the open. The hunt for a mate begins in the warmer months, with most mating finishing by early autumn.
#8. Jovial Jumping Spider
- Apricia jovialis
- Adults grow up to 10 mm (0.39 in) long.
- They have a dark color overall, with yellow bands on the abdomen.
- Their front two eyes are much larger than the rest.
Jovial Jumping Spiders in Western Australia prefer tropical areas.
They have excellent vision and are superb hunters during the day. These amazing creatures can calculate distances while observing their prey. Then, they move to a point out of sight and, with an immense leap, fly through the air to grab their victim.
Jovial Jumping Spiders are a great pest control agent due to their diet. They eat insects and other spiders, so if you see one in your flower beds, leave it to do its work! You’ll be rewarded with fewer bugs to take care of. 🙂
This species is not aggressive. It will almost always choose to run away if disturbed. However, their fangs produce venom, and the bite can be painful. Luckily, the venom doesn’t pose any health risks to humans.
#9. Leaf-curling Spider
- Phonognatha graeffei
- Females are 8-12 mm (0.31-0.47 in) long. Males are 5-6 mm (0.19 to 0.23 in) long.
- Both sexes have red-brown legs and bodies and a cream-colored pattern on their backs.
- They are oval-shaped and have long, tapered legs.
The Leaf-curling Spider gets its name from its habit of hiding inside a curled, dry leaf. It carefully weaves the leaf into the center of its web as a shelter to hide away from birds and other predators.
Leaf-curling Spiders usually rebuild their webs at night, so you’re not likely to spot them during the day. They’re also timid and reluctant to bite. So don’t fear this species; instead, appreciate its habit of controlling pest populations!
Unlike other spiders in Western Australia, Leaf-curling Spiders are communal.
Males and females, both adult and immature, live together in the same webs at opposite sides of the shelters. The males choose a female to pursue and then mate with her shortly after the female molts.
#10. Silver Orb Spider
- Leucauge dromedaria
- Females grow up to 15 mm (0.59 in) long. Males are around 6 mm (0.23 in) long.
- This species is distinguished by the “humps” on the abdomen.
- It has silver, black and yellow markings on a brown background.
Look for Silver Orb Spiders in garden shrubs, wooded areas, and swampland vegetation. This species creates a small, sloppy, horizontal web. They hang upside down in the web, so their silvery bodies are camouflaged against the sky, while their dark underside blends with foliage or soil.
This species must remain alert and cautious because plenty of animals prey on it. For example, birds and large bees often pick these spiders right out of the web! Wasps will even land on the web and lure the spider by imitating a struggling insect’s vibrations.
If disturbed, Silver Orb Spiders often drop to the ground and run away to hide. Though they rarely bite, their venom can result in numbness, swelling, and dizziness. Therefore, you should seek medical attention.
#11. Social Huntsman Spider
- Delena cancerides
- The body is light brown and covered in dense, fine hairs. The legs are also hairy and can be over 15 cm (5.9 in) long.
- The body length of females is 25-32 mm (0.98-1.26 in) long. Males are slightly smaller.
The Social Huntsman Spider is most famous for being the main star in the movie Arachnophobia. Even though it’s depicted as a vile and venomous spider in the film, its bite is not life-threatening to humans. One of the reasons this species evokes such fear is its unusually social behavior.
These spiders are incredibly cooperative, living together in tight spaces, and even sharing food. It’s not uncommon to find colonies of up to 300 spiders! If there’s one thing that people are more scared of than a spider, it’s LOTS of spiders working together.
Despite their communal lifestyle, they are highly aggressive. They will attack and even cannibalize Social Huntsman Spiders from other colonies. Additionally, they actively hunt for food instead of trapping it in a web.
You might be thinking this is a spider you want to avoid. Luckily, they think the same about us! Social Hunstman spiders are timid and reluctant regarding human interactions. Although bites are infrequent, they can cause swelling and excruciating pain. So even though they aren’t life-threatening, you should still get medical help.
#12. Spotted Ground Swift Spider
- Nyssus coloripes
Also known as the Fleet-footed Spider, Painted Swift Spider, and Orange-legged swift spider.
- Females grow up to 7 mm (0.27 in) long. Males are slightly smaller.
- The legs can be up to 3 cm (1.18 in) long.
- Their coloring is black with white lines on the body and legs. The front legs are orange or reddish.
Unlike most spiders in Western Australia, this species doesn’t make webs.
Instead, the Spotted Ground Swift Spider lives and hunts primarily on the ground. Their preferred habitat is open forests and grasslands, but they sometimes wander into houses and gardens. Most of the time, they can be found in leaf debris, on rocks, fences, or tree trunks.
This species has adapted to hunting during the day, not by camouflage but by becoming even more noticeable! Spotted Ground Swift Spiders have vivid coloring and markings that repel predators. In addition, they move quickly and tremble their front legs as a warning. This trembling mimics the behavior of wasps.
#13. Badge Huntsman Spider
- Neosparassus diana
- Females grow up to 22 mm (0.86 in) long. Males are around 17 mm (0.66 in) long.
- Their coloring is yellow, brown, or orange.
- The eyes are arranged in two straight rows with yellowish-white hairs between the rows.
The Badge Huntsman Spider is also commonly known as the Shield Spider. The names come from the large, colorful marking on their abdomen that looks like a police badge or shield.
This species prefers forested habitats with plenty of leaf litter. However, Badge Huntsman Spiders in Western Australia occasionally wander into homes or cars. They’re known to hide behind sun visors or run across the dashboard. I wouldn’t want to share my morning commute with one of these!
Unfortunately, Badge Huntsman Spiders are notorious for biting. Their venom can cause severe pain, sweating, nausea, swelling, and sometimes even vomiting. If the symptoms persist, you should seek medical attention. However, a cold pack can relieve temporary local pain from a mild bite.
#14. Black House Spider
- Badumna insignis
- The Black House Spider has a robust shape and is dark in color, usually black, dark brown, or charcoal grey, with a dorsal pattern of light grey or white markings.
- Females are 18 mm (0.70 in) long, with a leg length of up to 30 mm (1.18 in).
- Males are around 10 mm (0.39 in) long.
True to their name, Black House Spiders in Western Australia live inside human-populated areas. Look for them in window frames, crevices, dark corners, and garden walls.
If you find one of these spiders wandering around your house, it’s likely a male. The females of this species are very territorial and rarely leave their webs. Additionally, they are nocturnal, coming out at night to repair the web by adding new silk over the old.
Black House Spiders feed on insects that are attracted to light, such as moths, beetles, and termites. Consequently, they can be good to have around if you have a pest problem. These small, unassuming spiders are harmless to humans. Instead of killing them, try transporting them outdoors or allowing them to continue eating your more harmful bugs!
#15. Common Peacock Spider
- Maratus pavonis
- Females are about 48 mm (1.88 in) long. They are a flat brown or gray color and have a leaflike pattern on their abdomen.
- Males are around 38 mm (1.49 in) long. They have colorful abdomens with two red, aligned crescents that round a central red dot on a blue background.
Peacock Spiders in Western Australia are very small but extremely flashy!
This species is widespread in domestic gardens, but they often go unnoticed because they’re so tiny. You might also find them in forests, hiding in low shrubs or leaf litter.
Before mating, the male Peacock Spider performs a distinctive dance to attract a female. They often lift colorful flaps on their sides, stand and wave their third legs into the air, and expand their abdomens, showing beautiful colors. This performance resembles a peacock showing off his tail feathers.
Unfortunately, this mating display comes with quite a bit of risk. The female can choose if she likes the performance or not. She will often kill and eat the male spider if she doesn’t. There’s no “letting them down gently” in the world of spider dating! 🙂
#16. Gray Wall Jumping Spider
- Menemerus bivittatus
- This species has a flattened torso and short, thick, greyish-white hair. Tufts of dark brown hair grow close to the eyes.
- The male has a brownish-white stripe on each side of the abdomen and a black dorsal stripe.
- The female has a larger abdomen and is typically lighter brown. In addition, her abdomen is rimmed with broad black stripes that come together at the end.
- Both sexes are about 9 mm (0.3 in) long, but males are usually slightly smaller.
The Gray Wall Jumping Spider is native to Asia but has since spread worldwide. It frequently appears on the exterior of buildings or tree trunks in gardens.
Instead of weaving a web around its prey, the Gray Wall Jumping spider stalks the prey before springing on it to attack. Their wide eyes and visual acuity allow them to focus easily on objects and distinguish between colors. And, using their exceptional jumping ability, they can seize their prey in the blink of an eye.
Interestingly, male Gray Wall Jumping Spiders can produce sounds as part of courtship behavior. The hairs on their femurs and the teeth on the chelicerae (small claws on the front of the mouth) make clicking noises that attract females. These sounds are too low and quiet for humans to hear, but it isn’t hard to imagine the creepy noise!
#17. Green Jumping Spider
- Mopsus Mormon
- Females are 12-18 mm (0.47 to 0.70 in) long. They often have a red, white, or brownish-red pattern on the thorax.
- Males are about 15 mm (0.59 in) long. They display long white “whiskers” and a crown of black hairs.
- Both sexes have two pairs of very large eyes at the front, with smaller pairs behind.
This species is the largest jumping spider in Western Australia.
Green Jumping Spiders prefer to live in humid forests near populated areas. Especially in the summer months, you’re likely to find them in your backyard or garden.
Like other jumping spiders, the Green Jumping Spider doesn’t use a web to gather food. Instead, they actively hunt insects, jumping on them and immobilizing them with their bite. They don’t use webs as shelter but rather build nests inside long, curved leaves.
The Green Jumping Spider’s bite is not toxic to humans but is notoriously painful. So if you see one of these colorful spiders, it’s best to keep your distance!
#18. Leishman’s Hunstman Spider
- Isopeda leishmanni
- Adults are about 35 mm (1.37 in) long with a leg span of around 120 mm (4.27 in).
- Their coloring is dark gray, brownish, or black, sometimes with a lighter abdomen.
- This species’ body shape is flat, allowing them to live in narrow places.
Leishman’s Hunstman Spiders often live in loose bark on trees, under rocks, in crevices, and foliage. So be careful on your commute! They are also known to enter cars and hide behind sun visors. Don’t worry too much, though, since this species is not venomous to humans.
Unless it’s disturbed, the Leishman’s Huntsman Spider is entirely nocturnal. Instead, it actively hunts its prey by stalking and running after it. This species is particularly fast due to its large leg span, which is 30-40 times its body length.
Interestingly, this is one of the few female spiders that doesn’t eat its mating partner after reproduction. Instead, males often live peacefully with females after mating.
#19. Long-bodied Cellar Spider
- Pholcus phalangioides
- The cephalothorax (head) and abdomen are different shades of brown.
- Females have a body length of around 8 mm (0.31 in), with males slightly smaller.
- Legs are long and about 5 to 6 times the length of the body.
Do you know the spider that always seems to be in the corner of your basement? Well, it’s most likely the Long-bodied Cellar Spider! These long, thin, and delicate spiders are commonly found in Western Australia in homes and buildings as they prefer warm habitats (they originate from subtropical climates in Asia). I know that every time I clean my basement with a vacuum, a few of these spiders end up getting sucked inside.
Some people find cellar spiders beneficial because they are known to hunt down and kill other types of spiders. But unfortunately, they will also eradicate native spider species. Interestingly, these spiders will leave their webs to hunt for other spiders! Once they find one, they subdue their victim, using their long legs to avoid being bitten in retaliation.
Despite their proximity to people, they are not dangerous and are not known to bite humans.
#20. White Garland House Hopper
- Maratus scutulatus
- Females are about 7 mm (0.27 in) long. They tend to be duller in color, which helps them remain camouflaged.
- Males are 4-5 mm (0.15-0.20 in) long.
- Their coloring is black, brown, or beige. Some individuals have white-colored hairs on the legs, abdomen, and back of the head.
White Garland House Hoppers prefer moist, dense forests where they hide in tree bark and among leaves. They are active during the day when they use their excellent vision to hunt for small insects.
This species is commonly known as a peacock spider due to its colorful and dazzling patterns. The male often displays its colors during courtship. The female of this species does not have bright colors.
The White Garland House Hopper is not venomous to humans, but its bite may cause local pain, inflammation, or mild illness. You can take an over-the-counter pain reliever, but it’s best to seek medical help to prevent infection.
