The female Huntsman Isopeda , for example produces a flat, oval egg sac of white papery silk, and lays up to eggs. She then places it under bark or a rock, and stands guard over it, without eating, for about three weeks. During this period the female can be quite aggressive and will rear up in a defensive display if provoked. Some species will even carry their egg sac under their bodies while moving about.

Delena females lay a ground-sheet of silk upon which the egg sac is anchored while the eggs are laid into it. They will then complete her egg sac and pick it up, leaving the silk ground-sheet behind. Incubation periods vary and are probably influenced by climatic conditions. In some cases Isopeda , the female may moisten and tear the egg sac open, helping her spiderlings to emerge. The mother stays with them for several weeks. Young Huntsman spiders are pale.
