Numbers
one of 4 species in this genus in North America
Identification
Adult: forewing surface texture appears granulated or "pebbled"; AM and PM lines cream or off-white with edges that seem frayed, ragged, or wiggly; discal dots lacking on all wings; whitish middorsal line on thorax continues onto abdomen
Lynn Scott describes the adult thus:
"Wings somewhat pale grayish green, sometimes appearing slightly bluish. On the forewing, the cream-colored antemedial and postmedial lines are clearly defined, but somewhat variable as to straightness. On the hindwing, only the postmedial line is present. A pale terminal line is sometimes evident. The fringe is also pale, sometimes a paler shade of the blue-green of the wing. The surface texture of the wing often appears somewhat alligatored. Ferguson (1985) comments also that there are no distinctive abdominal markings, but most of the specimens I have photographed show a cream stripe beginning on the thorax and extending along the abdomen."
Genitalia:
Larva: body slender, light bluish-gray with dark purplish middorsal stripe and thin pale bands separating abdominal segments; head brownish

Nova Scotia to Florida, west in Canada to Manitoba, west in the US to the Rockies, and south into Mexico
Season
