Coordinator notes: I am not a moth guy but I checked your suggested ID in the Powell-Opler book (Moths of Western North America) and the description of the caterpillar matches perfectly with your picture, along with the host plant also noted in the book and so I am confident that your ID is correct. The adult moth is rather drab. Too bad its not as good looking as the immature. Sorry this took so long to get ID'd. Mike Post note on 12/19/2020: According to the note above, I previously identified/verified this sighting but perhaps something went wrong so I have verified it again.....Per the book referenced above, the adult moth is pictured on Plate 30 (#12) and the text is on p. 217. The moth belongs to the family Geometridae. Mike
