The Graybanded Leafroller (Argyresthia mariana) is a moth of the Yponomeutidae family. It is found in northern Ontario and possibly Alberta.
The wingspan is 7-8.5 mm. The forewings are pale, shiny golden yellow. The hindwings are whitish.[2] Adults are on wing from mid to late June.
The larvae feed on Picea mariana.[3] They bore into their host plant, starting near the base of a twig and moving toward and into the bud. Near the base of the bud an exit hole is cut where pupation takes place in the fall. Adults emerge the following summer after overwintering.
