title: A new species of Grapholita Treitschke (Lepidoptera: Tortricidae) from the midwestern USA.
abstract: Grapholita orbexilana, new species, is described from Illinois, Kentucky, and Ohio, USA. The larvae feed exclusively on Orbexilum onobrychis (Fabaceae), a plant of conservation interest in the Midwest. The moth is univoltine; its complete annual life cycle is detailed. Adult morphology readily distinguishes G. orbexilana from all other midwestern species of Grapholita; diagnostic information is provided. Observations on morphology, larval host plant preference, and pheromone attraction are presented to support the assignment of G. orbexilana to the jungiella species group of the subgenus Grapholita.
