This is the second edition of a comprehensive butterfly list produced by the Northern Prairie Science Center of the National Biological Service, U. S. Department of the Interior, under cooperative agreement with the author and Minot State University. Field work for the project was completed in the summers of 1995 and 1996. A primary objective of the project was production of a comprehensive, site-specific butterfly list that could serve as a basis for future monitoring of populations and as an aid in making management decisions at Sullys Hill National Game Preserve.
