skippers: Carson wandering skipper (Pseudocopaeodes eunus
obscurus) (Lepidoptera: Hesperiidae: Hesperiinae) Profile
prepared by Scott Hoffman Black and Mace Vaughan, The Xerces
Society for Invertebrate Conservation The Carson Wandering
Skipper is currently known from only two populations, one in
Washoe County, Nevada, and one in Lassen County, California. The
subspecies is found in grassland habitats on alkaline
substrates. The sites where viable populations are still found
are at risk because of livestock grazing, off- road vehicle
activity, encroaching development, gas and geothermal
development, changes in the water table, pesticide drift, and
non-native plant invasion. Xerces Society Red List Status:
Critically Imperiled Canada – Species at Risk Act: N/A Canada –
provincial status: N/A USA – Endangered Species Act: Endangered
USA – state status: None IUCN Red List: N/A In the late 1990’s,
P. eunus obscurus could be found at three locations: (1) near
Carson City, Nevada, (2) at Winnemucca Ranch in Washoe C
