Trichonephila clavipes (formerly known as Nephila clavipes), commonly known as the golden silk orb-weaver, golden silk spider, golden orb weaver spider or colloquially banana spider (a name shared with several others), is an orb-weaving spider species which inhabits forests and wooded areas ranging from the southern US to Argentina.

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. [15] 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 ...
Trichonephila can be found living in Africa, Oceania, Asia, Central America, the West Indies, South America, and the US' southeastern region and gulf states. [4] [5] These spiders like to make webs where prey is fruitful, often in open wooded areas, between tree branches, shrubs, tall grasses, and around light fixtures.
The spiders are golden orb-weavers, meaning they create webs with a slightly golden appearance to catch bugs and sometimes small animals to feed on. Male Joro spiders are relatively small, with ...
Fossil evidence shows that the orb web was in existence at this time, which permitted a concurrent radiation of the spider predators along with their insect prey. [12] [13] The capacity of orb–webs to absorb the impact of flying prey led orbicularian spiders to become the dominant predators of aerial insects in many ecosystems. [14]
The cribellate (lace-weaving) spider (Amaurobius) creates an untidy type of spider web from silk that looks blueish-grey when it is fresh. There is a retreat in the center where the spider waits ...
The web of females may reach several meters in length. In sunlight, the yellow threads appear to be a rich gold color. The structure of the web seen in cross-section is unusual for an orb web; it has three layers: the central orb, plus two irregular layers in front and behind the orb. Both males and females have large abdomen and long legs.
Nephila pilipes (northern golden orb weaver or giant golden orb weaver [2]) is a species of golden orb-web spider. It resides all over countries in East and Southeast Asia as well as Oceania. 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 ...
