To impress a female spider the male does a small dance and the spiders also tap their feet and abdomen on the ground in fast intervals that can’t be seen by the human eye.

Female spiders generally store sperm from different males inside their bodies and they make decisions to choose which male gets to fertilize her eggs. The process of mating is done only once from the female side and if any male tries to mate with females who are once mated creates a chance to be killed.

Eggs are laid within one to two weeks, in a thick fluffy sac, usually on the top of their enclosure. Eggs hatch within one to four weeks.

Most females bear only one clutch of eggs, but some lay more.
