False Widow Spider
Steatoda grossa
False widow spiders are small cobweb-weaving spiders often found in sheds, wall crevices, basements, and other sheltered places near human buildings as well as under bark and stones. They build tangled webs and wait for insects and other small arthropods to become trapped before moving in to bite and wrap prey. Their venom helps subdue prey and can cause a painful bite in humans, though serious effects are uncommon. Steatoda grossa is often confused with true black widows, but it is usually less glossy and lacks the classic red hourglass mark.
