Pisauridae

This family is commonly called the Nursery web or Fishing spiders. They are harmless to man.

In South Africa the Pisauridae include 10 genera, most of which are diurnal. Some are web-bound and some not although they are all three clawed spiders. The webs of the web bound species have no capture ability and the spiders rely on speed to capture their prey. One need only attempt to try and catch one of these spiders to appreciate the speed at which they move.

Pisaurids are medium to very large arboreal, terrestrial or water associated spiders, ranging from 8 to 30 mm. The carapace is longer than wide with the elongated abdomen tapering posteriorly. The legs are relatively long and slender and depending on the genus, are held forward and backward or latrigrade. The integument is normally coloured in various shades of brown with lateral creamish bands on the carapace that may extend along the abdomen. On some, the abdomen may be marked with spots or have a folium (leaf-like marking). Others may have a lightish (brown, grey or cream) median band running dorsally along both its carapace and abdomen.

All Pisaurids construct a round white egg case that is carried under the sternum held in the chelicerae (jaws). This causes them to assume a tiptoe stance. Just before the eggs are due to hatch, the female constructs a nursery web around the egg case. This is attached to the vegetation with a supporting web around it. The spiderlings leave the nursery after one or two moults.

Can anyone please confirm this or ID correctly. I'm not a 100% sure I got it right.

Thanx for viewing and I appreciate any crits.

This is a great macro with superb detail, colour, DOF, BG, and composition. The entire spider is soooo presicely in focus, and your usage of the flash resulted in a perfectly exposed photo.
Very well done and TFS.

Loot
