Web Spider Nephila pilipes (Fabricius) 1793 |
|||||
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. 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 (right, on 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.
