Denver Museum of Nature & Science (DMNS-DMNS)

Worldwide in scope though with a focus on the American West, the Entomology and Arachnology collections at the Denver Museum of Nature & Science collectively comprise over 1,000,000 specimens and specimen lots. The Entomology collection contains over 950,000 specimens, with Coleoptera (750,000+ specimens) and Lepidoptera (130,000+ specimens) as primary foci. The holdings include at least 18 primary types and 150 paratypes, and dates of collection span from 1878 to the present. The dung beetle collection is the largest in the United States, and our scarab holdings are particularly strong in African as well as regional material. The Colorado Scarab Survey and the Colorado Microlepidoptera Survey, both long-term projects initiated and conducted by DMNS, are steadily growing our regional holdings and our knowledge of the Colorado fauna. The Arachnology collection, with over 55,000 vials of specimens and specimen lots, is the sixth largest in the United States. Holdings are particularly strong in Colorado species and in Solifugae, with 13 primary types and 65 paratypes. The Colorado Spider Survey, initiated at DMNS and now in its 16th year, has vastly expanded our knowledge of the Colorado spider fauna. At the end of 2014, the Entomology collection moved to a new, state-of-the-art collections facility in the south wing of the museum; the Arachnology collection will be moving to the new facility in 2016.
