The golden silk orb-weavers (Nephila) are 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 also commonly called golden orb-weavers, giant wood spiders, or banana 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, they 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 whom their venom might be of little danger.
Golden orb-weavers reach sizes of 4.8–5.1 cm (1.5–2 in) in females, not including legspan, with males being usually 2/3 smaller (less than 2.5 cm, 1 in). The largest specimen ever recorded was a 6.9 cm (2.7 in) female N. plumipes (which is now debated to have been a new yet undocumented subspecies) from Queensland, Australia, that was able to catch and feed on a small finch. In 2012 a large individual was photographed killing and consuming a half-metre-long brown tree snake in Freshwater, Queensland.[3][4] Species from Taiwan have been known to reach over 130 mm (5.1 in), legspan included, in mountainous country.
