The family Hahniidae, commonly known as dwarf sheet spiders, belongs to the order Araneae (spiders). This small family is characterized by tiny, delicate spiders that build horizontal, sheet-like webs close to the ground or among vegetation. Hahniids are generally inconspicuous and often overlooked due to their small size, typically less than 4 mm in body length. They are found worldwide, with species inhabiting forests, grasslands, and leaf litter, where they capture small insects and other arthropods. Despite their diminutive size, they play an important ecological role as predators of small invertebrates, helping to maintain local ecosystem balance.
