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
Lepidoptera of New York and Neighboring States, Primitive Forms,
Microlepidoptera, Pyraloids, Bombyces (Ithaca, New York: Cornell University,
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
