Steatoda grossa, commonly known as the cupboard spider, is a small, dark-colored spider found in temperate regions worldwide. It typically inhabits human dwellings, weaving tangled webs in undisturbed corners. Its venom is mild and rarely harmful to humans, and it plays a crucial role in controlling insect populations.

Steatoda grossa, commonly known as the false widow spider, is native to Europe. However, due to human activities, it has expanded its range and is now found in many parts of the world, including North America, Australia, and New Zealand.

Steatoda grossa is commonly found in a variety of habitats that include indoor and outdoor environments. It prefers dark, undisturbed areas such as basements, garages, sheds, and under furniture. In outdoor settings, it can be found in leaf litter, under rocks, and within crevices.

This species is a synanthropic arachnid, meaning it often lives in close association with human habitats. Its ecological niche involves controlling insect populations, as it preys on various insects and arthropods. The spider is adaptable to a range of climates but thrives in temperate regions where it can exploit human structures for warmth and shelter.
