Distribution
North America: Ontario, Canada; northeastern and southwestern United States. Mexico: Federal District, Puebla, and Jalisco.
Seasonality
recorded on wing from May to September.
Host Associations
- Zea mays - possible larval Larval feeding on maize is suggested but not confirmed; may reflect unverified report or misidentification.
Human Relevance
Potential, unconfirmed association with maize raises possible agricultural concern, though no documented economic impact exists.
Similar Taxa
- Other Hahncappsia species share similar size range and general ; precise identification requires genitalia dissection.

Data quality note
Larval and relationships remain poorly documented. The maize association cited in some sources lacks primary verification and should be treated as tentative.
