Spider WebWatch is a biodiversity monitoring effort for biologists, naturalists, educators, students, and anyone else with a strong interest in spiders. From more than 4,400 species of spiders in North America, nine were chosen as eight-legged ambassadors. Learn to identify these nine species of spiders, view the sighting reports, and read active discussions between participants. You can make your own submissions, take a peek at what goes on, or dig a little deeper into the science of arachnology.
