Abstract
The US Fish and Wildlife Service has designated the butterfly Pyrgus centaureae wyandot (Appalachian Grizzled Skipper [AGS]) to be at-risk, based on its declining populations and the lack of information on its status. Our objective was to conduct range-wide surveys to locate extant AGS colonies and to quantify the number of AGS observed at each location. From 2021 to 2024, we conducted 284 surveys in 25 unique (i.e., distinct) counties in 8 states (Maryland, Michigan, New York, North Carolina, Ohio, Pennsylvania, Virginia, and West Virginia). We found AGS in only 2 counties: Alleghany County, VA, and Greenbrier County, WV. AGS were observed 180 times in these counties. Our results can inform US Fish and Wildlife decisions about where and how future AGS conservation efforts can be implemented.
