Identification
The combination of a dark triangular spot, three pale costal streaks, and a bright golden basal streak distinguishes this from other Argyresthia. The small size (approximately 10 mm wingspan) and specific wing pattern separate it from similar white micro- with metallic markings. Definitive identification may require examination of genitalia.
Appearance
Small with wingspan approximately 10 mm. Forewings display a blackish or dark brown, shining, nearly triangular spot at the apex. Three pale, indistinct brownish costal streaks present before the spot. Bright pale golden basal streak located just within the costal margin at the wing base.
Habitat
Oak woodlands. Associated with Quercus-dominated forest .
Distribution
Eastern North America. Documented from Florida, Kentucky, and Ohio.
Seasonality
active in June and July.
Diet
Larvae thought to feed on Quercus (oaks). Specific feeding habits unconfirmed.
Host Associations
- Quercus - probable larval based on collection and tentative inference
Behavior
attracted to light. Activity concentrated in summer months.
Ecological Role
Larval stage likely functions as or needle miner, based on -level of Argyresthiidae.
Similar Taxa
