"This species is similar to O. astrologana and O. coruscana but tends to have more gold on the forewing.
Overall, O. ferrolineana tends to have a "cleaner", less mottled look to it, with larger areas of pure orange-gold.
However, there is considerable variation, so dissection is the only foolproof method of separating these three similar species."...BugGuide
