The entomology collection consists of over 1,080,000 specimens (January 2019). The collection spans 1880 to present. Holdings are worldwide in coverage and comprise all major insect orders, with a particular focus on Coleoptera (86%) and Lepidoptera (12%). The collection also contains the terrestrial (including freshwater) non-arachnid, non-mollusc invertebrates (mainly millipedes, centipedes, and annelids). At its current rate, the collection is expected to grow by an average of 10,000 to 20,000 specimens per year, and the unprepared backlog is processed at a rate of 20,000 to 30,000 specimens per year. About 113,000 specimens of the entomology collection are currently catalogued and databased and can be freely accessed through the SCAN portal. In recent years, the collection was supported by three grants from the National Science Foundation.
