House spiders mainly prey upon small insects such as fruit flies. Spiderlings construct larger webs as they mature and require more food.

Its abdomen is spherically shaped, and is white to brown in color with several dark markings.
Males are smaller than females, and their legs are orange in color.
The female's legs are yellow. Biology Male house spiders are submissive during the mating process. When the female is ready to mate, she will alert the male by vibrating her web. Once signaled, the male house spider will approach the female and inject sperm into her with his palps. The male will retreat from the web if the female shows any signs of aggressive behavior.
