Size

Male WS: 20-26 mm (1)
Female WS: 18-28 mm (1)

Identification

Adult: forewing light yellowish-tan with brown AM, PM, and ST lines; brown orbicular and reniform spots; AM line arc-shaped with noticeable curving jog near inner margin; PM line wavy, irregular, with abrupt basal jog in lower half; ST line straight, diffuse, darker at both ends and faded near middle; hindwing slightly paler, semi-transparent, with partial PM line

Range

Ontario and northeastern states (DE, IA, IL, MD, MI, NJ, NY, OH, PA, WV) plus southwestern states (AZ, CA, TX) and perhaps states in between but no records were found on the Internet as of June 2008); type specimen collected in Arizona

Season

adults fly from May to September

Food

larvae possibly feed on corn but no confirmed records available

See Also

In other Hahncappsia species, forewing orbicular and reniform spots are less noticeable and subterminal line is of uniform weight, not faded near middle (compare images of several species by Jim Vargo at MPG)
Hahncappsia coloradensis: "Postmedial and subterminal lines are present on the hindwing of pergilvalis and are absent in coloradensis" (1)
H. mancalis is similar to H. pergilvalis, but tends to have a much stronger and straighter subterminal line on the forewing.
The H. marculenta/neomarculenta/neobliteralis complex has more diffuse markings and tends to be more translucent yellow, and the subterminal line of the hindwing is further from the outer margin(1).
