Coordinator notes: I don't think Cycnia oregonensis has any spots on the wings. It would also have a yellow head, which can't be seen well enough here. This is likely either Spilosoma congrua or S. virginica. The former has an all-white abdomen while the latter has lines of alternating black and yellow spots down the abdomen.
