Numbers
2 subspecies: E. d. detersa and E. d. personata listed at All-Leps
Size
wingspan 30-35 mm (1)
larvae to 34 mm
Identification
Adult: forewing yellowish to dark brown, dark specimens tinted with gray; lines double, white-edged; orbicular and reniform spots whitish with dark brown outlines, and dots in their centers; hindwing dark brown (1)
E. d. detersa typical form has pale strip along costa of forewing, and dark shading between reniform and orbicular spots (see example from Maryland); another form from Canada and the Great Lakes lacks the pale strip and is more uniformly colored (see example at CBIF)

Larva: body white to pale gray; pulsations in blood vessel along back can be seen through cuticle; faint chalky-white stripes on back and sides; head dull reddish-brown
[description by U. of Illinois]
Range
Newfoundland to North Carolina, west to Nebraska, north to Alberta and Northwest Territories
Covell's Guide (1) gives a southern limit of South Carolina but there are no Euxoa species on this list from Furman U. nor this list from the Dominick Collection in South Carolina
Habitat
sandy habitats: beaches, river shores, dunes, sandy agricultural fields, dry grasslands
adults visit flowers such as goldenrod during the day, and come to light at night
Season
adults fly from July to October
Food
larvae feed on corn, grasses, cranberry, saltwort, sea-rocket, various garden crops and commercial grains
Life Cycle
one generation per year; overwinters as a partially-grown larva
Remarks
Larvae construct subterranean burrows to feed on underground portions of host plants, and can be very destructive in fields planted in sandy soils.

"The commonest autumn dart to be found supping nectar from flower in the daytime." (Comment by David Beadle)
