The photos at top center and top right are of the same specimen.

My identification of the specimens illustrated above as Telphusa latifasciella is based on Internet resources and the description in Forbes, William T.M., The Lepidoptera of New York and Neighboring States, Primitive Forms, Microlepidoptera, Pyraloids, Bombyces (Ithaca, New York: Cornell University, 1923).

Telphusa longifasciella has a powdery gray forewing, black in the basal area. A wide antemedial stripe, typically white but sometimes pale gray, is bounded by a raised black line on either side.  In the darker gray medial area, a pair of small black tufts can be seen at the end of the cell.  The costal end of the irregular and interrupted blackish postmedial line is followed by a whitish shade.  The fringe may be partly streaked with dark gray.  The hindwing is grayish.  Forbes (1923) indicates a wingspan of 13 mm for this species.

According to Forbes (1923), the larva of Telphusa latifasciella is a leaf-roller on oak.  He indicates an adult flight season in May, but my few records suggest late June and July.

My records to date for Telphusa latifasciella (each date representing "the night of") are in the table below:
