Souvent confondu avec : It is often confused with black widows and redbacks (Latrodectus species), which have a bright red hourglass pattern that this spider lacks. Steatoda borealis is similar in shape but slightly smaller and found in colder climates. It has coloured markings on the top of the abdomen rather than the underside.1
