Life History

It likes to sunbathe and typically holds its front two pairs of legs together pointing forwards. During mating the male presents the female with a carefully wrapped insect as a present. The female carries her eggs in a ball shaped, pea-sized sack with her. Just before the babies hatch she builds a silk tent and puts them inside for protection. Feeds on flies and other small insects. It uses quick sprinting and strength to overpower its prey.
