The Common rain spider (Palystes superciliosus) is native to Southern Africa. They are called rain spiders because they enter homes before rain to prey on geckos. After mating the female constructs a round egg sac of silk, which she guards aggressively until the spiderlings hatch inside the protective sac and chew their way out. Their large size combined with the yellow and black banding on the underside of the legs, give them a fearsome appearance but their bite is no worse than a bee sting and will heal quickly.
