On an overcast afternoon, this moth was flitting about where a grassy area borders coastal sage scrub at the Claremont Colleges' Robert J. Bernard Biological Field Station. After looking at moth photos, I wondered if it might be a Californian Granite, Digrammia californiaria Hodges#6380. But I could be way off — there are so many moths! Any information will be greatly appreciated!

Update: Although the reviewer at Butterflies and Moths of North America initially confirmed Digrammia californiaria, he decided after further review that although it may be D. californiaria, he did not feel he could tell it apart from D. delectata, and maybe even D. denticulata.
