Food
The larvae feed on a wide range of plants and are considered a pest on apples and pears. Recorded host plants include: ''Medicago'', ''Malus'', ''Prunus'', ''Taxodium distichum'', ''Phaseolus'', ''Vaccinium'', ''Betula'', ''Acer negundo'', ''Aesculus'', ''Ceanothus'', ''Cercocarpus'', ''Citrus'', ''Quercus'', ''Eriodictyon'', ''Vitis'', ''Crataegus'', ''Carya'', ''Gleditsia triacanthos'', ''Humulus'', ''Syringa'', ''Avena'', ''Allium'', ''Maclura pomifera'', ''Pyrus'', ''Rheum'', ''Sassafras'' and ''Juglans'' species. First instar larvae bore into the buds of their host plant. Later instars roll or tie leaves together or tie them to fruit. They feed on the leaves, flowers, buds or fruits of the host plant. Pupation takes place within the larval shelter.References:
