A rapid assessment of spider diversity in Kabigan Falls, Pagudpud, Ilocos Norte. Spiders are the most permeating predators in both agricultural and natural ecosystems. In ecological studies, they serve as indicators of environmental quality and as biological control agents in agricultural ecosystems. A total of 38 individuals collected from Kabigan Falls were comprised of 13 species. These species are from the family Araneidae, Sparassidae, Pholcidae, Salticidae, and Tetragnathidae. Most of the specimens collected from the site were under families Tetragnathidae and Araneidae. The most species-rich family is Araneidae (5). These include the following: Araneus inustus, Cyclosa insulana, Cyclosa mulmeinensis, Cyclosa spirifera and Larinia sp.
