Adult: forewing dull purplish-red except dark purplish-gray median area; AM line whitish, gently S-curved; PM line whitish, jagged; no subterminal line; hindwing whitish to pale gray with brown terminal line and white fringe Larva: body dull white; head dark brown with heavily chitinized black areas; spiracles and anal shield smoky brown; pair of jointed legs on each thoracic segment, and fleshy prolegs ending in numerous hooked spines (crochets) on abdominal segments 3 to 6 and 10; consequently, very mobile within and outside gallery [adapted from description at forestpests.org]

Habitat and Range

Habitat

parks and woodlands containing Tuliptree

Geographic Range

eastern United States: Arkansas and Louisiana to northern Florida, north to Michigan and New York (approximately the same distribution as Tuliptree , the larval hostplant)

Seasonal Activity

adults fly from April to June and again from August to October (two broods) in southern states

Diet and Behavior

Diet: larvae bore into bark and feed on phloem at base of Tuliptree ( Liriodendron tulipifera ) Magnolia reported to be attacked (USDA FS 1985), but this is questionable. (It seems more likely that a related borer in magnolia, E. magnolialis Capps, was mistakenly identified as E. ostricolorella .) [forestpests.org]

Life History

Females oviposit at night in bark crevices of hostplant; larvae tunnel into bark to feed; two generations per year in southern states; one generation in northern states Overwinter in the pupal stage in an tunnel excavated by the larva.

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Euzophera ostricolorella. 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.
