Virginia State Rank: S1S3
VA DGIF Tier: None
Federal Legal Status: None
Virginia Legal Status: None
Description: The wingspan is 25 mm. The postmedian line is visible on the forewing of both sexes, but it is not enlarged or darkened at the costa. The underside of the hindwing of both sexes is slightly yellowish and the dorsal side of the hindwing of the female is also slightly yellowish.
Similar species: There are no similar species that occur in its range.
North American Range: Maine to New York, Pennsylvania, New Jersey, Virginia and West Virginia.
VA Observations by Locality: Rockbridge
Flight season and broods: Adults fly from mid-June to early July.
Habitat and Food Plants: Ridgetops and sand plains, in pitch pine-bear oak barrens, on sandy soils, or granite and other rock outcroppings. Bear Oak (Quercus ilicifolia) is thought to be the only food plant of this species.
Behavior and Ecology: This moth is most likely completely nocturnal. Eggs hibernate and larvae feed in spring. It probably pupates and overwinters underground. Adult flight season seems variable but between approximately June 10 and July 20. Flight season is brief, typically about two weeks.
Population trend and potential threats: Only the brief pupal stage might have any protection from fires. Summer fires are a threat.
Management practices: Fire in any other season than that of the pupal stage is thought to be very detrimental to this species, so entire habitats should not be burned all at once, but rather in piecemeal sections.
