  • 1493 Cosmopterix clemensella: "The key in Koster (2010) relies on the clemensella forewing being greyish brown and lespedezae dark brown, which is very subjective and hardly accurate. Otherwise clemensella should have a 4x larger outer dorsal spot than the opposite costal spot (lespedezae is 2-3x). I have also found this to be an unreliable character. The only possible distinguishing character I can find is the middle longitudinal white line is shorter in clemensella." - Steven Whitebread (pers. comm., 4/1/2020).
