This butterfly is brownish to yellowish orange on the upper side and yellowish below. It is 2.5 to 3.2 centimeters in length. This species occurs on alkali flats. The caterpillar of the species feeds on saltgrass (Distichlis spicata var. stricta). There is little other information about the biology of the species.

FWS Digital Media Library — The U.S. Fish and Wildlife Service’s National Digital Library is a searchable collection of selected images, historical artifacts, audio clips, publications, and video.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 County, Nevada, and (3) near Honey Lake in Lassen County, California. At the first of these, the butterfly appears to have been extirpated due to development and a misguided attempt at wetland restoration.
