Unknown Brown Butterfly - Hesperopsis libya

Trona Pinnacels, San Bernardino County, California, USA

I'm pretty sure this is a Saltbush Sootywing (Hesperopsis alpheus).

 
Jason, I haven't been in this discussion
since west coast leps are a learning process for me. I am curious why you think this is Saltbush Sootywing? From various guides, Saltbush male has mottling, subapical spots bend distally, and checkering of the fringe of the dorsal forewing which I do not note on this specimen.

Hesperopsis libya
Nice find! There are only half-a-dozen other submissions of this species in the guide!

Pholisora catullus is somewhat similar on the upperside, but I'm pretty sure this is the correct identification.

One thing I should note, is that the county given (Orange County), is incorrect, and should be changed as Trona Pinnacles is in north-western San Bernardino County. In this case it made the identification tougher, as I assumed it was the Common Sootywing based on location. As I researched it, though, it kept seeming to turn out as a Mojave Sootywing, which has never been found in Orange County! I finally figured this out by searching the web for Trona Pinnacles.
