Pseudocopaeodes eunus is a rare species of butterfly known by the common name alkali skipper. It is native to northern California and Nevada in the United States,[1] and Baja California in Mexico.[2] There are five subspecies.[3] One, ssp. obscurus, the Carson wandering skipper, is treated as a federally listed endangered species of the United States. As of 2007 there are four known populations.[4]
This butterfly is brownish to yellowish orange on the upper side and yellowish below. It is 2.5 to 3.2 centimeters in length.[2]
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.[1]
