Cellar Spiders (Family Pholcidae)

Family Pholcidae comprises a diverse group of spiders commonly known as cellar spiders or daddy-long-legs spiders. Belonging to the order Araneae, these spiders are widely distributed around the world and are especially common in tropical and subtropical regions. They typically have small, slender bodies and very long, delicate legs, although body proportions vary among species. Many inhabit caves, rock crevices, tree hollows, leaf litter, and sheltered areas of buildings, where they construct loose, irregular webs used to capture insects and other small arthropods. When threatened, some species rapidly vibrate their bodies and webs, making them difficult for predators to locate. Certain pholcids also prey on other spiders, including species that may be larger than themselves. Through their feeding habits, Pholcidae help regulate populations of small invertebrates and contribute to the ecological balance of natural and human-associated environments.
