Female: 30-50 mm.
Male: 5-6 mm.

The female spins a strong, vertical web with a golden tinge. The web is not a symmetrical orb, but the hub (centre) is usually nearer the top. The mesh is fine, and it remains small at the edge of the web because the radial threads (equivalent to the spokes of the wheel) split into branches as they spread out from the hub towards the periphery.

Closer examination of the web will show that the mesh may be highly irregular because the golden sticky line which spirals its way towards the hub often follows a zig-zag course.

The first, second and fourth pairs of legs of juvenile females have dense hairy brushes at the tibiae, but these hairs are shed as the females approach maturity.

There appears to be a gap in every few whorls of golden spirals, giving an appearance of staves of music scores on the web (most noticeable in the part of the main web immediately below the spider in the picture above). Sometimes, the main orb-web of the spider is protected by barrier webs on both sides, as shown in this picture.

The male (below the female's abdomen) is much tinier than the female.

Before laying eggs, the female digs a pit on the ground and produces her egg-sac there. The egg-sac is then covered with plant debris and soil.
