From Hellhole Canyon in Anza-Borrego Desert State Park, Feb. 14, 2006.

The Arizona Powdered Skipper is more common in Arizona. This photo is from the Boyce Thompson Arboretum east of Phoenix, on Sept. 25, 2007.

I found several larvae of Systasea zampa on mallows on the fringe of a nursery in Palm Desert on Oct. 19, 2015.
