He courts the female by jerking on a silken thread which is connected to the scaffolding of her net. Soon after fertilization takes place, the male dies. Later the female constructs a spherical egg-case, of very strong brown silk, which is suspended on strong silken threads measuring 3-5 mm long. The egg-case is globular in shape, 10-12 mm in diameter and is pink-brown to pale brown in colour, with dark brown to black specks; it is also smooth to slightly rough in texture with a thick watertight covering.
