Came to my Coleman lantern the night before at the South Prong Camping Area. I have not seen a Digrammia this dark anywhere on BG or MPG. The only species that seems to make sense is D. atrofasciata. Many of the posted images of that species have a median line. This specimen may also have a median line, but the AM line is so thick that it may be merging with the median line. I found a couple others at this location the same night and at Palo Duro Canyon the previous week that had double AM and PM lines and also had median lines. Just thought this one really stood out and would make a nice contribution to BugGuide.
