Family Araneidae
The female moves around in the central area of the web and there also attaches the egg sac.
The web is often found in plants such as aloes.They are medium-size spiders with eight eyes in two rows.
Often seen with legs retracted, they do not look like spiders at all and are easily overlooked in the clutter of the nest.
When attacked these spiders will drop to the ground where their colour helps them to blend in and become almost invisible.
