Definition
A theridiid is any spider belonging to the family Theridiidae, known as cobweb or comb-footed spiders. These spiders are characterized by their irregular, three-dimensional webs. They often inhabit corners, crevices, and other sheltered spots. Theridiids are skilled hunters, using their webs to trap unwary insects. The comb-like structure on their hind legs aids in wrapping prey. They are a widespread and diverse family of spiders.
