Insect injured shoot tips were discovered in the fall of 1971 on larch (Larix spp.) in a mixed larch provenance plating in Shiawassee County, Michigan. Tortricid larvae collected later from them were reared to maturity and identified as Paralobesia palliolana (McDunnough 1938). McDunnough (1938) described this species as Polychrosis palliolana from insects taken in flight but without definitely associated hosts. The holotype he designated was collected at Milford, Nova Scotia; other specimens he examined were from Quebec and Ottawa, Canada.
