While walking through coastal sage scrub at the Claremont Colleges' Bernard Field Station, I flushed a lot of little seemingly white moths that practically disappeared when they landed. The moths seemed especially numerous in a stand of Skunk Bush (Rhus aromatica), and I finally got a photo of one that landed on a Skunk Bush. My best guess is that it's in Crambidae, and I'm wondering if it might be Agriphila attenuatus - Hodges#5404. The appearance seems very similar, and the location and time of year are certainly consistent with other BugGuide reports of that species. Any information about its identity will be greatly appreciated!
