The Albert J. Cook Arthropod Research Collection (MSU-MSUC)

In 1867, Professor Albert J. Cook started the ARC and it currently houses ~ 1.5 million specimens mounted on pins, slides or stored in alcohol representing ~35,000 species. A significant portion of the collection represents the insect diversity Michigan and the Great Lakes Region. Other significant collections represent the world-wide arthropod fauna for select taxa, e.g., Lepidoptera and Scolytinae. Researchers in systematics, agriculture, natural resources, urban insect management, to extension personnel and to the general public use these specimens.
