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 theory is that flying insects do not notice the web, fly into it, and get stuck. Orb webs created by Araneidae, Tetragnathidae and Theridosomatidae spiders are made of sticky silk so the ...
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 sumptuosa, the red-legged golden orb-web spider, is a species of golden orb-web spider. [2] [3] Description.
There are a few possibilities: The spider is biting the firefly, the spider weaves it silk around the firefly, or the spider's venom is affecting the firefly. An orb-weaver spider manipulates a ...
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]
