Museum collections are important to document historical and present-day species distributions and abundance. Tracking insect declines and asssessing ecosystem health using insect biomonitoring requires accurate species identifications, up-to-date species catalogs, and digitization and georeferencing of label data. We present a comprehensive, updated catalog of Odonata species present in the Cornell University Insect Collection. We also provide digitized and georeferenced records for seven widespread odonate species to demonstrate the value of historical museum collections.
