Identification

The can be distinguished from other Acrolophus by its dark coloration, reflected in the "dark acrolophus." Acrolophus species in general are recognized by their association with grasses and the silken tubes constructed by larvae. Identification to species level likely requires examination of genitalia or other microscopic features.

Appearance

Small with wingspan of approximately 20 mm in males and 26 mm in females. Specific coloration and pattern details are not documented in available sources.

Habitat

preferences are not explicitly documented, but the is associated with grassy environments based on the -level trait of larval tube-spinning at grass bases. Occurs in suburban and rural settings where grasses are present.

Distribution

Eastern North America. Documented from Quebec, Vermont, New Hampshire, Massachusetts, New York, New Jersey, Maryland, Virginia, West Virginia, North Carolina, South Carolina, Georgia, Florida, Kentucky, Tennessee, Ohio, Illinois, and Mississippi.

Seasonality

activity period is not explicitly documented, but the has been observed at blacklights during National Week events in late July, suggesting summer period.

Host Associations

  • Grasses - larval Inferred from -level ; Acrolophus larvae are known as 'grass tube moths' that spin silken tubes at grass bases or roots for concealment while feeding.

Life Cycle

Complete with , larva, pupa, and stages. Larvae construct silken tubes at the base of grasses or among grass roots for concealment while feeding. Specific details for this are not documented.

Behavior

are and attracted to artificial light sources, including blacklights and porch lights.

Ecological Role

Larvae function as herbivores feeding on grasses. likely serve as prey for including bats, birds, and predatory arthropods.

Human Relevance

No documented economic importance. Occasionally encountered by citizen scientists during -watching events and blacklight surveys.
