The U.S. National Entomological Collection is the world's second largest, with over 35 million specimens. The electronic records available here focus on type specimens as well as the general Odonata collections. Data for several taxonomic groups are indicated, at the end of detailed records, as reveiwed by staff of the Smithsonian or affiliates USDA Systematic Entomology Laboratory and Walter Reed Biosystematics Unit. Legacy data for several taxonomic groups are kept available while under review and will be udpdated upon completion. Data and images for all specimens should be considered provisional. We will be updating and adding records and images regularly.
