Pseudocopaeodes eunus
alkali skipper, Carson wandering skipper (for ssp. obscurus)
Pseudocopaeodes eunus is a rare skipper butterfly endemic to alkali flat habitats in the western United States and Mexico. The species comprises five recognized subspecies, with P. e. obscurus (Carson wandering skipper) federally listed as endangered due to habitat loss and extremely limited distribution. As of 2007, only four populations were known to persist. The species is highly specialized, with larvae dependent on saltgrass as their sole documented host plant.
