Hanging around some more
|[Note Guidelines] Photographer's Note|
|Female Golden Web spider (Nephila senegalensis annulata) black and yellow abdominal markings with yellow bands on its legs. It has a wide distribution throughout South Africa. |
These large, obtrusive spiders are one of the few spiders which can be identified down to species without the aid of a microscope and a fancy key. They are strictly web bound and find walking on the ground cumbersome. Nephila construct very large orb webs, often between trees or bushes from 1.5m to 6m above the ground. Their silk is golden in colour and extremely strong. There are trip lines around the web and quite often prey remains are strung up to form a line through it’s center. Their slightly angled webs are designed to catch large flying insects and small birds are occasionally snared, but rarely eaten. The female spider hangs inverted in the center of the web, while one or more males lurk on the periphery of the web. Males are many times smaller than the females and can be distinguished by their swollen
pedipalps which are similar to boxing gloves.
Reproduction is similar for all Nephila. As in the case of Nephila senegalensis annulata, the male spins a small sperm web onto which he deposits a drop of sperm which he sucks up into his pedipalps. He will usually only approach the female when she is otherwise occupied i.e. feeding. He descends towards her and inserts his pedipalps, one by one, into her genital opening which is situated underneath her abdomen. Copulation may take as long as 15 hours
and afterwards the now exhausted male retreats to a safe place away from the female. When ready to lay her eggs, she selects a suitable site and constructs an egg sac using special loopy white silk. After a fortnight or so, the young spiders hatch inside the eggsac.

Hola Willem: Hermosa araña has capturado con tu màquina. Me recuerda a la araña de oro, por su gruesa tela dorada. Son atractivas y espeluznantes. Me gusta el encuadre y la nitidez de la foto. Felicitaciones.

an admirable close-up of the spider walking a tightrope. Excellent sharpness and background. Well composed.
Best wishes, Peter
:) points later!
Great picture ! I like everything in it : sharpness and colours of course, but also, and especially, the original POV from aside and the background : it crosses the lines of the web and all these diagonals do a really beautiful composition.
