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.

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
