Common house spiders are variable in color from tan to nearly black, frequently with patterns of differing shades on their body.

[citation needed] The spiderlings remain in the mother's web for several days after coming out of the egg sac.

Bigger females can also attract baby skinks inside their web by leaving fly remains hanging in it.

Once its food dries out, the spider usually drops it to the floor in order to free space in its web, instead of destroying and rebuilding it or changing its location.

[5] The latter one often falls prey to its own food when it gets trapped in the tangling web after missing the jump on its target.

The assassin bug Stenolemus lanipes (Emesinae) apparently feeds exclusively on spiderlings of this species, but can also become prey of the adult spider.
