- It has 3 different names, the golden orb spider, the giant wood spider, and the banana spider.
- They can be found in regions such as Africa, Asia, Australia, and the southeastern United States.
What is the lifespan of an orb weaver?
Orb weavers live one to two years, on average. The orb weaver's web is a masterful creation, designed to ensnare meals efficiently. The spokes of the web are primarily non-sticky silk and serve as walkways for the spider to move about the web.

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.
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 do golden orb weavers eat?
Golden Orb Weavers are known to occasionally eat prey as big as small birds and even snakes. N. clavipes (and many other Nephila species) are frequently victimized by Argyrodes, a genus of very small black-and-silver spiders that are kleptoparasitic. As many as a few dozen may infest a single Nephila web to feed from the host spider's captured prey.
How does the golden orb weave work?
Typically, the golden orb-weaver first weaves a non-sticky spiral with space for 2-20 more spirals in between (the density of sticky spiral strands decreases with increasing spider size). When she has completed the coarse weaving, she returns and fills in the gaps. Whereas most orb-weaving spiders remove the non-sticky spiral when spinning the sticky spiral, Nephila leave it. This produces a " manuscript paper " effect when the orb is seen in the sun: groups of sticky spirals reflecting light with "gaps" where the non-sticky spiral does not reflect the light.
What are the golden silk orb weaver spiders called?
They are also commonly called golden orb-weavers, giant wood spiders, or banana spiders. In North America, the golden silk orb-weavers (see also Nephila clavipes) are sometimes referred to as writing spiders due to occasional zigzag patterns ( stabilimenta) built into their webs, though these occur much more frequently in the webs of Argiope, ...
What is a golden silk orb weaver?
The golden silk orb-weavers (genus Nephila) are a genus of araneomorph spiders noted for the impressive webs they weave. Nephila consists of numerous individual species found around the world. They are also commonly called golden orb-weavers, giant wood spiders, or banana spiders. In North America, the golden silk orb-weavers (see also Nephila clavipes) are sometimes referred to as writing spiders due to occasional zigzag patterns ( stabilimenta) built into their webs, though these occur much more frequently in the webs of Argiope, such as the St Andrew's Cross spider .
What is Nephila silk used for?
Another possible use of Nephila silk lies in tissue engineering. A study from the Medizinische Hochschule Hannover reports that processed Nephila silk is an excellent scaffold material thanks to its biocompatibility, mechanical strengths, and its property to promote cell adhesion and proliferation.
What is the purpose of golden orb weaver?
The Australian golden silk orb-weaver ( Nephila edulis) has been observed on windy, rainy days dismantling the lower part of its web to allow strong wind to flow through a large opening in the web without breaking it. Golden Orb Weavers are known to occasionally eat prey as big as small birds and even snakes.
Do Orb Weaver Spiders Bite?
Orb weaver spiders are not aggressive and are often reluctant to bite.
Are Orb Weaver Spiders Dangerous to Humans?
Of the 3000 species of orb weavers known, none is dangerous to humans.
Are Orb Weaver Spiders Poisonous?
Although orb weaver spiders have mild venom, they are not poisonous to humans.
Are Orb Weaver Spiders Poisonous to Dogs?
While orb weaver spiders contain venom, the venom is harmless to humans and pets because it is mild. Orb weaver spiders are not poisonous to dogs and other pet animals. Unless your dog tries to eat an orb weaver, it will not bite. However, if the dog gets bitten, the orb weaver’s bite still won’t be enough to hurt your dog.
How many generations does Trichonephila clavipes have?
Trichonephila clavipes in temperate North America has one generation per year under field conditions. Adult males are present from July to September, with most females maturing in August. Mature females are found late into the fall, when they make at least two large eggsacs 2.5 to 3 cm in diameter consisting of several hundred eggs surrounded by a basket of curly yellow silk. Populations in the tropical parts of the range probably produce more eggsacs, as the related Trichonephila maculata (Fabricius) averaged nearly nine eggsacs per female in New Guinea (Robinson and Robinson 1973a). The life history of Trichonephila clavipes has not been studied through all the instars, but it is probably quite similar to Trichonephila maculata (Robinson and Robinson 1976), with one or two fewer instars.
How big are Trichonephila clavipes?
Females range from 24 mm to 40 mm in length. The female color pattern, consisting of silvery carapace, yellow spots on a dull orange to tan cylindrical body, brown and orange banded legs, plus the hair brushes (gaiters) on the tibial segment of legs, I, II, and IV, make this spider one of the most easily recognized. The males, on the other hand, are rather inconspicuous dark brown, slender spiders averaging 6 mm in length which would often go unnoticed if not for the fact that they are often found in the webs of females.
What is the name of the spider in Florida?
Introduction (Back to Top) In Florida and other southeastern states, the golden silk spider, Trichonephila clavipes (Linnaeus), a large orange and brown spider with the feathery tufts on its legs is well know to most native southerners.

Different reports say that the flavor is somewhat like mixed raw potato and lettuce mixed, or nutty flavored like peanut butter with a stick y consistency (Robinson and Robinson 1976).
Which species of eriophora captures larger prey?
However, due to their use of immobilization wrapping as a primary attack weapon (Robinson 1969, Robinson and Olazarri 1971, Robinson et al. 1969), Argiope and Eriophora species are able to capture larger prey on the average than do Trichonephila species which directly employ biting to subdue the prey.
Where does Trichonephila clavipes live?
It occurs throughout Florida, the West Indies, as far north as North Carolina, across the Gulf States, through Central America, and into South America as far south as Argentina.
Which species was first recognized as an araneoid?
One of the distinct groups of species that was recognized and named relatively early in the history of araneoid nomenclature was Nephila (Leach 1815). MacLeay (1834) apparently was the first to recognize that Aranea clavipes Linnaeus belonged in the genus Nephila.
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 a Nephila?
Nephila is a genus of araneomorph spiders noted for the impressive webs they weave. Nephila consists of numerous species found in warmer regions around the world. They are commonly called golden silk orb-weavers, golden orb-weavers, giant wood spiders, or banana spiders .
What do young spiders look like?
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 silver stripes or patches on their abdomens, described in some references as a form of heat control). The best distinction between Leucauge and Nephila juveniles is web structure: Leucauge species tend to build horizontal orbs that form a perfect circle, whereas Nephila species build vertical, elliptical orbs that are incomplete (missing the portion of the orb over the hub, the center where the spider sits). The latter seem to prefer more open habitat such as second-growth scrub or forest edges. Fences or building overhangs often do just as nicely.
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.
