The females lay their eggs in November or December. The eggs are round, about the size of a mustard seed, and are a transparent, purplish red. They are held together in a cream-coloured, round, ball shaped egg sac which is about in diameter. The female constructs five or six egg sacs over the next three to four weeks. Each egg sac contains about 70 to 90 fertilised eggs. The egg sacs are hung in the centre of the spider's web and the female spins more silk over them. Over time, the exterior of the egg sac may become covered with sand. After six weeks of incubation, during January and February, the spiderlings hatch. The young spiders then disperse from the web. Little is known about the dispersal mechanism that the spiderlings use to move away from the nest. In one study, observing spiders over 24 hours, 28% used a ballooning method, which is where the young spiders use air currents to carry themselves away from the nest suspended by a single web strand, while the majority, 61%, used a bridging method where the spiderling uses its silk to move to nearby plants, and 11% still remained in the nest. The young spiderlings reach full maturity the following spring.
