Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONATechnical Description, Adults: Hodges (1966)                                                                                 
Adult Markings: The following description is based on that of Hodges (1966). The head is orangish-white and somewhat lighter than the forewings. The antenna is about three-fourths the length of the forewing, and is brownish orange with faint annulations. The labial palp is ascending and slightly recurved, and the apex of the second segment has some brownish scales. The thorax is light to pale orange with a thin, median brownish orange line. The forewing ground color is pale orange and overlaid with grayish orange. The apical fourth is overlaid with light brown. There is an elongated brown spot near the middle of the wing and just beyond one-half the wing length. A second smaller spot is often evident at about four-fifths and below the tornus. At the wing tip, there is a narrow, brown, curved band in the cilia that extends around the apex then fades as it extends towards the dorsal cilia. The dorsal cilia are mainly pale orange, but often have a second fainter dark band near the middle. The hindwing is pale orangish-gray and tinged with yellowish white distally. The cilia are mainly pale orange. The legs are pale orange to grayish orange or orangish white, and the abdomen is orangish to orangish white. Hodges (1966) noted that the amount of brown on the forewing varies substantially.
Wingspan: 11.5-15 mm (Hodges, 1966)
Adult Structural Features: Hodges (1966) provides detailed descriptions and illustrations of the male and female genitalia.
