Nathan Banks (April 13, 1868 – January 24, 1953) was an American entomologist noted for his work on Neuroptera, Megaloptera, Hymenoptera, and Acarina (mites). He started work on mites in 1880 with the USDA. In 1915 he authored the first comprehensive English handbook on mites: A Treatise on the Acarina, Or Mites (Smithsonian Institution, Proceedings Of The United States National Museum, 1905, 114 pages).
