Do orb weaver bites hurt?
That said, orb weavers, like all spiders, can and will bite if they feel threatened. Because they are often found outdoors, people can happen across a web at any moment, and disturbing their nests can result in painful bites that result in itchy welts on the skin.
What is a golden orb spider?
As stated earlier in our intro, the golden orb spider is not called that because it is made of gold or banana spider because it looks like a banana or is found on a banana but because it shoots out webs that look the same color as a banana and is sometimes found in banana shipments. You probably weren’t aware of this right? well below are some key points you should take note of about the golden spider: 1 A golden orb spider, also called the giant wood spider is easily identifiable by its long legs, brown or yellowish hue, and unique golden web. 2 It has 3 different names, the golden orb spider, the giant wood spider, and the banana spider. 3 They can be found in regions such as Africa, Asia, Australia, and the southeastern United States. 4 This beautiful wonder of nature shoots out golden web silk. 5 Its specie is the oldest surviving spiders on earth. 6 They have very quick abilities to escape very tense situations. 7 The biggest orb spider ever known was discovered in Australia and was known to be 2.7 inches in length. Females are usually bigger than males. 8 One very striking fact is that the female golden orb spider feeds on the male after mating (Besides they’re bigger).
What are banana spiders?
Golden orb spiders! sometimes referred to as banana spiders are easily identifiable by their long lanky legs, brown or yellowish hue, and unique golden web. But what are they for real? why are they called banana spiders? the mention of banana quickly brings to memory the picture of a yellow, elongated, edible fruit usually taken by humans and animals as well.
What is a golden orb spider?
These large spiders are well known in South Africa for their magnificent golden webs. The webs are huge, often spanning a large area between bushes. The web is strong, and we have seen small birds trapped in the webs. The female spiders are large, and the web often contains multiple spiders. The Golden orbs usually have black legs and a yellow to white abdomen. They are harmless to humans and pets.
What color are golden orbs?
The Golden orbs usually have black legs and a yellow to white abdomen. They are harmless to humans and pets. Map indicating the distribution of Golden Orb spiders, within Southern Africa.
Where do spiders live?
They are native to Australia. Spider Identification - large spiders 20 mm to 30 mm in body length - has a bulbous abdomen with fine hairs - silvery-grey to plum coloured bodies and brown-black, often yellow banded legs.

What spiders weave a web?
All orb weaving spiders make suspended, sticky, large circular web of 2 metres or more, often between buildings and shrubs, to snare flying insects, such as, flies and mosquitoes. These spiders remain in their webs day and night. After mating, the Golden Orb Weaving Spider wraps her single egg sac in golden silk, ...
What does a spider do to the orb web?
The spider removes and consumes the portion to be replaced, builds new radial elements, then spins the new spirals. This partial orb renewal is distinct from other orb-weaving spiders that usually replace the entire orb web. The web of Nephila antipodiana contains ant-repellent chemicals to protect the web.
Where do golden silk orb weaver spiders live?
Golden silk orb-weavers are widespread in warmer regions throughout the world, with species in Australia, Asia, Africa (including Madagascar ), and the Americas. Spiderlings can be carried by the wind over long distances, and each year, a small number of female golden orb web spiders are found in New Zealand (where they are not endemic) after having been blown across the Tasman Sea; the spiders usually end up in the North Island.
Why do Nephila spiders renew their orbs?
As with many weavers of sticky spirals, the orb is renewed regularly if not daily, apparently because the stickiness of the orb declines with age.
What is the web of Nephila antipodiana?
The web of Nephila antipodiana contains ant-repellent chemicals to protect the web. Typically, the golden orb-weaver first weaves a nonsticky spiral with space for two to 20 more spirals in between (the density of sticky spiral strands decreases with increasing spider size).
How do Nephila spiders change their body?
Nephila spiders change their body positioning relative to the sun to maintain internal temperatures at an optimal level. As ambient temperatures increase, the spiders position themselves so the abdomen shades the cephalothorax from the sun. Spiders may also hang from their hind legs as a result of the heat due to a loss of hydrostatic pressure. Conversely, as temperatures cool down, the spiders position themselves perpendicular to the sun to retain as much heat energy as possible. When ambient temperatures reach extreme highs (above 40 °C), they may leave their webs and seek shade in the surrounding environment.
What color are Nephila spiders?
Nephila spiders vary from reddish to greenish yellow in color with distinctive whiteness on the cephalothorax and the beginning of the abdomen. Like many species of the superfamily Araneoidea, most of them have striped legs specialized for weaving (where their tips point inward, rather than outward as is the case with many wandering spiders). Their contrast of dark brown/black and green/yellow allows warning and repelling of potential predators to which their venom might be of little danger.
How big do golden orb weaver snakes get?
Golden orb-weavers reach sizes of 4.8–5.1 cm (1.5–2 in) in females, not including legspan, with males being usually two-thirds smaller (less than 2.5 cm, 1 in). In 2012, a large individual was photographed killing and consuming a 0.5-m-long brown tree snake in Freshwater, Queensland.

It is commonly found in primary and secondary forests and gardens. Females are large and grow to a body size of 30–50 mm (overall size up to 20 cm), with males growing to 5–6 mm. It is the second largest of the orb-weaving spiders apart from the recently discovered Nephila komaci.
What is golden web?
The N. pilipes golden web is vertical with a fine irregular mesh. It is not symmetrical, with the hub usually nearer the top. Rather than egg sacs being hung in the web, a pit is dug which is then covered with plant debris or soil.
Why do spiders balloon?
Ballooning is a common behavior among spiders. Spiderlings can disperse via wind to larger areas after birth to avoid overcrowded habitat and competition for resources. Research conducted in lab has found that N. pilipes will display ballooning behavior when the wind speed reaches a threshold of 3.17 m/s. However, ballooning is subject to many influences in wild habitats, such as wind angles, humidity, temperature, and pressure. Ballooning is also a social behavior. When the majority of spiderlings balloons, some spiderlings will sense the decline of the population and stay in the original place. Ballooning behavior explains the wide spread of N. pilipes, and sometimes colonization of islands.
Where do N. pilipes spiders have sexual dimorphism?
Sexual dimorphism appears to be a shared feature among N. pilipes spiders of different populations, as examinations of populations in Southeast Asia, Australia, and Papua New Guinea show similar patterns of size dimorphism.
What color are golden orb weaver spiders?
Golden Orb Weavers are large spiders with a body length of 2 to 4 centimetres with silvery-grey to plum coloured bodies and brown-black, often yellow banded legs. The males are tiny measuring only 5 millimetres and red-brown to brown in colour.
What is an orb weaver spider?
Orb-weaving spiders are three-clawed builders of flat webs with sticky spiral capture silk. The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. The spider secures the line and then drops another line from the centre, producing a ‘Y’ shape. The rest of the web is then constructed before the final sticky capture spiral is woven into place. Some species of Orb Weaver spiders remain in their webs day and night.
What is a silver orb weaver?
Humped Orb Weavers or Silver Orb Weavers are easily recognised by their silvery body, with yellow or green and black markings. They have long bodies and long limbs, with a body length of about 1 centimetre. The abdomen often has rounded ‘shoulder’ humps that give these spiders their common name.

Orb Weaver Spiders This family of spiders is a very large one and includes over 2800 species in over 160 genera worldwide, making it the third largest family of spiders known behind the jumping spider family (Salticidae) and the second largest family of spiders called Linyphiidae commonly known as Sheet Weavers because of the shape ...
What are the predators of orb weavers?
Predators of orb weavers include several bird species and wasps of the family Sphecidae. The wasps land on the web, lure the spider to the perimetre by imitating a struggling insects vibrations and then carry the spider away to be paralysed and stored as live food for their young.
What is the band of silk in an orb weaver's web?
One feature of the webs of some orb-weavers is the ‘stabilimentum’, a crisscross band of silk through the centre of the web. It is found in a number of genera, but Argiope, which includes the common garden spider of Europe as well as the yellow and banded garden spiders of North America, is a prime example. The band has been hypothesized ...
How do golden orb weaver spiders work?
Golden Orb-weavers build their web in a classic wheel-shape with spoke-like threads radiating from a hub. An outer frame of stiff support threads connect the web to trees, wires, or other supports which may be spaced many metres apart. Lying across the supporting spoke threads are finer and more elastic threads that encircle the hub in parallel rows. These are armed with beads of glue to snare flying insects. The female hangs waiting at the hub with her front legs facing downwards. The hub is not central, but rather set closer to the top edge of the web. The web creates a sensory zone for the spider extending far beyond her slender feet. Spiders are ultrasensitive to vibrations transmitted through surfaces, so the web gives the spider a tactile reach of about 1 metre.
Why are golden orbs so big?
Because Golden Orb webs are large and tend to remain in the one place for long periods, they offer great opportunities for a wide range of other spiders to either live in the web or build an adjoining web.
Where can I find golden orb weaver?
Humped Golden Orb-weavers, sometimes called Coastal Golden Orb-weavers, are found in northern coastal areas with most records from coastal Queensland and New South Wales. However, they occur as far south as central-coastal New South Wales. This is the species commonly seen in Brisbane. The so-called ‘humps’ on this spider are really two bumps or mounds on their underside near the base of their second leg with other smaller bumps posterior to these.
Where can I find Edulis spiders?
The scientific name ‘edulis’ means edible and it was christened with this name after the original describer noted indigenous people eating this spider in New Caledonia.
Overview
Behavior
Nephila spiders produce large asymmetric orb webs up to 1.5 m (5 ft) in diameter. Nephila species remain in their webs permanently, so have a higher predation risk. The golden silk orb-weaver is named for the yellow color of the spider silk used to construct these webs.
Yellow threads of their web shine like gold in sunlight. Carotenoids are the main contributors to this yellow color, but xanthurenic acid, two quinones, and an unknown compound may also aid in …
Etymology
The genus name Nephila is derived from Ancient Greek, meaning "fond of spinning", from the words νεῖν (nein) = to spin (related to nema νήμα "thread") + φίλος (philos) = "love".
Description
Nephila spiders vary from reddish to greenish yellow in color with distinctive whiteness on the cephalothorax and the beginning of the abdomen. Like many species of the superfamily Araneoidea, most of them have striped legs specialized for weaving (where their tips point inward, rather than outward as is the case with many wandering spiders). Their contrast of dark brown/black and green/yellow allows warning and repelling of potential predators to which their …
Species
In 2018, twelve Nephila species were reclassified as Trichonephila, with another two (N. kuhlii and N. robusta) considered in 2020 to be junior synonyms of N. pilipes. Species whose placement has been changed by some sources include:
• Nephila laurinae was considered to be a synonym of Trichonephila antipodiana ("Batik Golden Web Spider"), found most commonly in the Philippines and Vietnam
Distribution and habitat
Golden silk orb-weavers are widespread in warmer regions throughout the world, with species in Australia, Asia, Africa (including Madagascar), and the Americas. Spiderlings can be carried by the wind over long distances, and each year, a small number of female golden orb web spiders are found in New Zealand (where they are not endemic) after having been blown across the Tasman Sea; the spiders usually end up in the North Island.
Life cycle
Nephila spiderlings leave the egg sac as a result of environmental cues, often warmer and wetter conditions in spring. They then live on a communal web, eating dead siblings and web debris for around a week before dispersing to make individual webs.
Young spiders do not generally build yellow-colored silk, and the young themselves can be easily mistaken for young orchard spiders (Leucauge) in general color and shape (both genera sport si…
Venom
The venom of the golden silk orb-weaver is effective in action on prey, but has not been reported to be of any notable consequence for humans if accidentally bitten. In the literature, Nephila is one of several genera where the venom "must be considered as more or less ineffectual in human beings". That said, the potentially large size of several members of the genus means that they possess relatively strong chelicerae, so any bite can cause some mechanical damage, but only o…
