The golden silk weaver orb spider (or golden orb spider) known as Nephila, evolved about 165 million years ago. Fossils of the golden orb are the largest recorded fossils of a spider and it was around 15cm. Today the average female has the leg span of about 5cm (2 inches), while the male is only two thirds her size. These spiders have been known to live through out the world in warmer climates, and in Taiwan they are known to reach around 5 1/2 inches. A large specimen was photographed eating a small finch in Queensland Australia. They get their name from the golden silk they weave.
