Larval feeding type: Leaf-miner. The mine is usually a rather compact blotch, with most of the frass deposited at the base. It pupates in a case made from a leaf cut-out. The larva is whitish, with a pale brown head. The pupal cut-out is usually about 5 mm long and has a central longitudinal ridge; because of this ridge, the pupal case becomes more of an oval shape than the roundish cut-out left in the leaf. It is attached to the pupation site by four stout silken threads extending from each end.
Larval substrate: Vitis aestivalis* (Summer Grape), Vitis labrusca* (Fox Grape), Vitis riparia (River Grape)
Phenology: Adult: 6/29 to 7/06 (2 records)
