The family Anyphaenidae, commonly known as anyphaenid sac spiders, belongs to the order Araneae. These spiders are generally small to medium-sized, agile hunters that do not rely on webs to capture prey, instead actively stalking insects and other small arthropods. They are often nocturnal and are found on foliage, under bark, or in leaf litter, where they create silken sacs or retreats for resting during the day. Anyphaenids are widespread, occurring in diverse habitats across the Americas, Europe, Africa, and Asia. Many species are recognized by their pale or muted coloration, elongated bodies, and characteristic movements when disturbed, and they play an important role in controlling insect populations in their ecosystems.
