Skadsen, D.R. 2001. Additional surveys for the Dakota Skipper [Hesperia dacotae (Skinner, 1911)] at Big Stone National Wildlife Refuge and Prairie Waterfowl Production Area, Minnesota. Final report submitted to the Natural Heritage and Nongame Research Program, Minnesota Department of Natural Resources. 15 pp.
Surveys were conducted to locate populations of Hesperia dacotae during the species 2000 flight period on the Big Stone National Wildlife Refuge and Prairie Waterfowl Production Area located in western Minnesota. Due to an apparent early hatch the flight period was coming to an end when surveys began on 28 June 2000. One male Dakota skipper was captured and four others were observed on the Prairie Waterfowl Production Area on 28 June 2000, and one female was observed at this site on 5 July 2000. One female Dakota skipper was captured on Big Stone NWR management unit 1A on 6 July 2000. All specimens were showing considerable wing wear at the time they were captured.
