Hi Daniel,
Here are two photos I took of what I think is a California sister last weekend. It was on a willow in the bed of the Arroyo Seco a little upstream of Hahamongna Watershed Park.

Dear Scott,
Thanks so much for sending in your images of a California Sister,
Adelpha californica, and it is wonderful that you were able to capture both a dorsal view and closed wing view revealing the ventral surface.  According to BugGuide, they are found in “Mostly mountain and canyon terrain. Associated with Oaks (Quercus species, which are the larval food plants.”
