The Northern Arizona University - Arthropod Collection (NAAC), previously the Colorado Plateau Museum of Arthropod Biodiversity (CPMAB), houses over 250,000 arthropod specimens, primarily from the southwestern United States and Mexico. Specimens are being added each year, primarily from Military Reservations, National Parks and Monuments, The Nature Conservancy, and a network of common gardens managed by the Southwest Experimental Garden Array (SEGA). Many specimen occurrence data are combined with high resolution images.
