The OSAC is the largest insect collection in the PNW with nearly 3 million specimens. We are used by researchers both here in Oregon and around the world who require access to research grade specimens to conduct their scientific studies. Many of these scientists are discovering new species and genera, or seeking to understand the evolutionary history, as well as biological complexity, of insects that live here. But many other types of researches and non-researchers use the collection as well.
