Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Munroe (1972)                                                                                 
Adult Markings: This species is easily recognized by its rounded forewing and the dark-fuscous and almost uniformly colored head, palp, thorax, forewing and hindwing. The markings on the forewing are obscured by the dark coloration. The antemedial line is obliquely curved, and the orbicular and claviform spots are small, blackish fuscous, and set on the antemedial line (Munroe, 1972). The orbicular is more basal than the claviform, and the postmedial line is almost straight and more-or-less runs parallel to the termen.
Wingspan: 12-15 mm (Forbes, 1923)
Adult Structural Features: Munroe (1972) has descriptions of the male and female genitalia and an illustration of the female genitalia.
Genitalia and other structural photos
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
Immatures and Development: The larval life history is undocumented.
Distribution in North Carolina
Distribution: Scoparia penumbralis is found in eastern North America. It occurs in southern Canada from Saskatchewan eastward to Nova Scotia and Price Edward Island, and in the US from Maine westward through the Great lakes region to northern Minnesota. Populations extend southward through the Appalachian region to western North Carolina, eastern Tennessee and northeastern Alabama. As of 2023, all of our records except one are from the Blue Ridge, where individuals have been collected from a wide range of elevations. We have one record from Hanging Rock State Park in the Piedmont in mountainous terrain.
