Hugh, Rich, Diana, et al, I'd like to weigh in on the discussion concerning Olethreutes. I believe Diana's moth is most likely O. ferrolineana based on the preponderance of gold on the forewing. After checking the plates and descriptions in Gilligan et al (Olethreutine of the Midwestern United States), there is also a size difference between the 3 species (O. ferrolineana, O. coruscana, and O. astrologana); O. astrologana tends to be signficantly smaller than the other two, 5.5-8.5mm vs 7-10mm for the other two. I also had an Olethreutes this morning that I've seen in previous years. My moth is tiny, approx. 5.5 mm and is much darker than Diana's moth with alternating bands of orange and black of about equal proportion. I believe my moth is probably O. astrologana based on its small size and overall darker coloration. I've attached a photo for comparison. I agree with Hugh that this complex is probably not separable to species; however, I also think that some individuals that are distinctly smaller and darker overall, such as my moth, can be identified as O. astrologana with some degree of confidence.
