The Entomology Collection documents many of the great explorations of the past, from the early explorers through expeditions such as Galathea, Mangarevan, and Pacific Entomological Survey (Polynesia), as well as critically important biological survey s such as Fauna Hawaiiensis, Insects of Micronesia, Southwest Pacific and Southeast Asia arthropods of medical importance, the Terrestrial Arthropod Survey of Fiji, and numerous recent arthropod surveys of French Polynesia. Also documented are smaller but equally important early individual projects and explorations such as Insects of Samoa, New Guinea, Insects of Guam, subantarctic islands. Large theoretical projects also are vouchered in these collections, for example, ship trapping and air trapping projects that showed that insects can disperse through the Pacific using air currents. The collections themselves have been most currently used to further the understanding of island biogeography. None of these are duplicated elsewhere.
