Welcome to the Oregon State Arthropod Collection the largest entomological research collection in the Pacific Northwest. Our history extends back into the early years of the Oregon State College (1860's/1870's). Since then, we've continued to grow and support entomological research and teaching at OSU and the entire region.
Today, we are a research collection of nearly 3 million specimens representing insects and other arthropod species from around the world.
