Habitat and Range

Geographic Range

Eastern half of the United States and adjacent Canada.

Diet and Behavior

Diet: The larvae bore into the buds and young shoots of cottonwoods, such as Populus balsamifera and P. deltoides , as well as some poplars (which are in the same genus).

Life History

Overwinter as larvae either in silk covered shallow pits excavated in healed-over borer entrance holes, in th margin of corky bark ridges below leaf bases, or in depressions of leaf scars. ( 3 ) When young larvae resume activity in spring they enter the tender, new shoots to feed and complete their development. The older overwintering larvae kill the bud and up to 10" of the terminal. ( 3 ) 4-5 generations in the Miss Delta region. ( 3 )

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Gypsonoma haimbachiana. 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.
