Compare with the similar Choristoneura rosaceana - Oblique-banded Leafroller. These are difficult to tell apart and it's possible this may be that species. From looking at photos on bugguide, I'm under the impression that C. rosaceana is more bell-shaped, flared out at the end of the wings, but there's no guidance for separating the two species.
