Egg mass

This species exhibits striking sexual dimorphism, the small male often waiting on the periphery of the web. An important characteristic of the female is the present of black brushes along the legs.

The web is remarkably strong and has a characteristic yellow colour as does the fluffy egg sac which tends to be left in the tree the spider was using for support. Nephila webs normally contain a string of debris masses which are the remains of insects the spider has eaten. The tendency to produce such a string is rare among orb weaver species so this is a useful identification feature.

In many parts of south-east Queensland this species is present in very large numbers, especially throughout the warmer months of the year. It is common for a single dead tree to have as many as 30 individual golden orb-weaver webs attached to it.
