A somewhat tentative suggested identification because given the angle of the photo, we cannot clearly see the dorsal view of the moth. I think the markings fit Labdia oxysema but there is a narrow white marking down the midline dorsally which would be visible. Does Cristy Froehlich have another photo with a dorsal view of the moth?
