Appearance
Small with wingspan of 28–36 mm. Forewings appear layered or doubled. Specific coloration and pattern details are not well documented in available sources.
Habitat
Associated with deciduous forests and wooded areas where potential plants occur. Specific microhabitat preferences are not well documented.
Distribution
Southern Canada (Manitoba, Saskatchewan, Quebec, Ontario) and the United States, ranging south to Florida and Texas. Eastern North American distribution with western records in the Great Plains.
Seasonality
on wing from May to September, with timing varying by geographic location. Likely multivoltine in southern portions of range.
Host Associations
- Quercus - probable larval Larvae probably feed on leaves of Quercus , though this association is not definitively confirmed
- Rubus - unconfirmed 'raspberry bud ' suggests potential association, but not substantiated in scientific literature
- Prunus persica - unconfirmed 'peach sword stripe night ' suggests potential association, but not substantiated in scientific literature
Life Cycle
Complete with , larva, pupa, and stages. Specific details of egg deposition, larval instars, site, and stage are not documented in available sources.
Ecological Role
Larval stage likely functions as a folivore in deciduous forest . Specific ecological impacts are not quantified.
Human Relevance
suggest potential economic concern for raspberry and peach , but no documented evidence of significant agricultural impact was found in available sources.
