Nephila

Nephila is a genus of araneomorph spiders. 
They are also known as the golden silk orb-weavers, golden orb-weavers, giant wood spiders, or banana spiders. Males are smaller than females. Females often get a choice to mate and share gifts with their mates.
"Nephila" spiders have large sexual dimorphism in size, with females being much larger than males.
"Nephila" species are often parasitized by "Argyrodes", a genus of very small black-and-silver spiders. These small spiders are kleptoparasitic: they live by stealing food from their hostess.
