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 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.

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Lacanobia subjuncta. Species-specific details appear above.

Group overview

Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.

Ecological role of the group

Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.

Economic and practical significance of the group

Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.

Recorded sources for this group: IUCN Red List, Xerces Society, USFWS, PNAS, WWF. Imported estimates may describe particular regions or reporting periods.
