https://en.wikipedia.org/wiki/Steatoda_bipunctata With a holarctic distribution, it is common in Europe and North America. It may be found in proximity to human structures, such as basements or sheds.
The abdomens of both sexes are bulbous and brownish in coloration, typically with a broken pale line down the center and another pale line across the anterior portion of the abdomen. The apodemes (places of muscle attachment) on the dorsal side of the abdomen look like pairs of dark dimples and presumably give the spider its Latin name bi- (two) and -punctata (spots). The underside of the abdomen reveals a most interesting pattern resembling the infinity sign. The female abdomen is light brown and often shiny compared to the males.
It spins a three-dimensional criss cross tangle at floor level or in the corners of ceilings and windows. The spider is frequently seen in this web which can become quite large in the absence of cleaning. If disturbed, the spider rushes away and hides itself. Steatoda bipunctata is a common house spider, but is also sometimes found in forests, usually under loose bark on tree trunks.
