What is a golden orb web spider?
Golden Orb Web Spider. The genus name roughly translated from Ancient Greek, means “fond of spinning”, a testament to the enormous webs the golden orbs weave.

How strong is a spider's web?
The dragline silk that holds up their webs appears to be delicate floss. But it is stronger and stretchier than steel. It has to be. This web must be tough enough to hold any insect prey it catches, together with the weaver — which can reach 7 centimeters (nearly 3 inches) long — and her mate.
What do golden orb weaving spiders eat?
Golden orb weaving spiders prey items include flies, beetles, locusts, wood moths and cicadas. Sometimes their strong webs manage to trap small birds or bats, and the spider will wrap them and feed upon them. The Golden Orb Weaving Spiders build large, semi-permanent orb webs. The strong silk has a golden sheen.
What are the adaptations of an orb weaver spider?
Other behaviours and adaptations. The Golden Orb Weaving Spiders build large, semi-permanent orb webs. The strong silk has a golden sheen. These spiders remain in their webs day and night and gain some protection from bird attack by the presence of a 'barrier network' of threads on one or both sides of the orb web.

What is the difference between Golden Orb Weaving Spiders and Nephila plumipes?
Golden Orb Weaving Spiders are large spiders with silvery-grey to plum coloured bodies and brown-black, often yellow banded legs. The males are tiny and red-brown to brown in colour.

The commonly seen Garden Orb Weavers are stout, reddish-brown or grey spiders with a leaf-shaped pattern on their fat, roughly triangular abdomens, which also have two noticeable humps towards the front.
What spiders eat spider webs?
Their webs are often host to the small kleptoparasitic spiders of the genus Argyrodes (often the Quicksilver Spider, Argyrodes antipodeanus) which inhabit the larger spider's web and eat the smaller insects that become trapped on the web, thereby helping keep the web clear of debris. Toggle Caption.
What are the predators of orb weavers?
Predators. 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 perimeter by imitating a struggling insect's vibrations, and then carry the spider away to be paralysed and stored as live food for their young. Danger to humans.
Do spiders vibrate their webs?
The strong silk has a golden sheen. These spiders remain in their webs day and night and gain some protection from bird attack by the presence of a 'barrier network' of threads on one or both sides of the orb web. Like the St Andrew's Cross Spider, they will vibrate their webs to distract potential predators.
What is a golden orb web spider?
Golden Orb Web Spider. The banded legged nephilia, commonly known as the golden orb spider, is a member of the nephila genus of arachnids. There are many species of nephila around the world, often referred to as golden orb-weavers, giant wood spiders or banana spiders.
Why is the golden orb spider so famous?

It can deliver a painful bite if severely provoked, but the venom is not lethal, generally only causing redness and blistering. ...
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.
