The Symbiota Collections of Arthropods Network (SCAN) grew from the Southwest Collections of Arthropods Network TCN (Thematic Collections Network), which focuses on ground-dwelling arthropods. SCAN will continue to add data for all arthropod taxa with a focus on North America. SCAN is built on Symbiota, a web-based collections database system that is used for other taxonomic data portals, including (Symbiota Portals). SCAN is the primary repository for occurrence data produced by the Lepidoptera of North America Network TCN (LepNet). We also serve arthropod data produced by InvertEBAse TCN and encourage museums to serve mollusk records on their data portal.
