Steatoda
False Widow Spiders, Cupboard Spiders
Steatoda is a genus of cobweb spiders in the family Theridiidae containing approximately 120 recognized species with worldwide distribution. Many species are synanthropic, commonly found in human dwellings, sheds, garages, and undisturbed corners. Members are frequently mistaken for widow spiders (Latrodectus) due to similar body shape and web structure, earning them the common name "false widows," though they are significantly less harmful to humans. The genus includes both native and invasive species, with Steatoda nobilis (Noble False Widow) being particularly notable for its rapid range expansion in Europe and North America.
