Synonyms and other taxonomic changes
originally Hadena subjuncta (Academy of Natural Sciences)
wingspan 34-50 mm
Adult: forewing purplish-gray with reddish-brown shading; AM and PM lines double, scalloped; black bar runs from outer end of claviform spot to PM line; basal dash black, curving toward orbicular spot at outer end; ST line with W shape near middle, containing two black streaks that extend toward PM line; subterminal area may be lighter than remainder of wing, but not conspicuously so
hindwing light yellowish-gray with prominent dark veins

Larva: early instars light green with white lateral stripe; later instars light brown with darker markings on dorsal surface
coast to coast in southern Canada and northern United States, south in the west to California and Arizona
gardens, fields; may be a pest in orchards
adults fly from May to September
larvae present in June and again in August and September
larvae feed on various plants, including apple, asparagus, blueberry, cabbage, cherry, corn, maple, pear, poplar, willow
Life Cycle
two generations per year; overwinters as a pupa in soil; adults emerge in May and June
Larvae in orchards will remain in trees during the day, unlike other cutworms which return to the ground and only feed in trees at night. They eat entire leaves and may also excavate holes in fruit.

Grand Arches (Lacanobia grandis) is similar but has a conspicuous pale band in subterminal area (Compare images of both species)
