Are Nephila cannibals?
Sexual cannibalism is uncommon in Nephila as a result of male mating behaviours. By copulating when females are immobile after molting or inactive due to feeding, the males increase their chances of survival. Males also approach from the side of the web opposite the female, increasing the odds of a successful approach.
What is eating my Nephila web?
Nephila species are frequently parasitized 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.
Is a golden silk spider venomous?
Toxicity. The venom of the golden silk orb-weaver is potent but not lethal to humans. It has a neurotoxic effect similar to that of the black widow spider; however, its venom is not nearly as powerful. The bite causes local pain, redness, and blisters that normally disappear within a 24-hour interval.

What is the difference between N. pilipes and Nephilia clavate?
pilipes has a few different features which make it easy to distinguish from closely related species. Unlike Nephilia clavate, N. pilipes has a horn-like bulge on its tergum. Additionally, it has a pair of yellow stripes at its back of the abdomen unlike Nephilia laurinae .
How many seasons does Nephila spp. live?
will abandon the web. Unlike other relatives, the distribution of N. pilipes doesn't depend on seasons. Adult females are active throughout four seasons and continuously lay eggs. Adult males are present in the population for longer times than females.
Where do Nephila lay eggs?
Other Nephila spp. lay eggs near their webs and cover the eggmass with a thick layer of silk. Then the eggmass is firmly tied to leaves and tree branches around it. The eggs are always found beneath leaves or other shades, which prevent direct UV light from the sun. However, N. pilipes is different from all other Nephila spp. Female N. pilipes lay eggs in small pits on the ground to avoid predation and parasitism.
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.
Do N. pilipes have dwarfism?
N. pilipes display female gigantism and male dwarfism (see Sexual dimorphism section). In terrestrial animals, N. pilipes have the most size differences between males and females. This can be explained by the evolutionary selection for females with better fecundity. Female N. pilipes have huge parental investments to their progenies, including egg production and web construction (see Parental care section).
Description
Like most orb-weavers, the species displays marked sexual dimorphism in both size and color pattern. T. clavipes females are some of the largest non-tarantula spiders in North America, ranging from 24 mm to 40 mm in length when fully developed. It is possible that they are even the largest orb-weaver species indigenous to the United States.
Population structure, speciation, and phylogeny
According to some scientists, Trichonephila clavipes belongs to the spider family Nephilidae, or golden orb-weaving spiders. However, other researchers have done away with the Nephilidae family, instead assigning all golden orb-weaving spiders to the subfamily Nephilinae, within the family Araneidae.
Distribution and transport
T. clavipes occurs most commonly in the Antilles and in Central America from Mexico in the north through Panama in the south. Less abundantly it occurs as far south as Argentina and in the north it occurs in parts of the southern states of the continental USA.
Mating
In T. clavipes, males move from web to web, attempting to mate with the female web-owners. Males risk death with each move to a new web, largely due to predation, and this mortality risk increases as the breeding season progresses, so that the risk is lower in the early stages of the season and highest in its later stages.
Webs
T. clavipes females construct large, vertical, asymmetric circular ("orb"-shaped) webs. The main web of a mature female can range from 1–2 meters in diameter, not counting the main filaments that anchor the web between trees; such anchor filaments may be 2–3 meters in length.
Bites to humans and animals
The spider is not aggressive and only bites if handled roughly; the venom is relatively harmless and rarely causes more than slight redness and temporary localized pain.
Significance to humans
T. clavipes has been incredibly useful in the study of spidroins; its spidroins were the first to be characterized, and its genome has been the first of the orb-weaving spiders to be annotated, contributing information about 28 unique spidroins. In addition, T.
Overview
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.
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.
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 …
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…
