Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1954)                                                                                 
Adult Markings: A medium-sized Idia with a powdery luteous ground color shaded with fuscous (Forbes, 1954). The lines are contrastingly black and deeply dentate, particularly the postmedian, and a strong blackish shade is present in the middle of the wing below the cell. The orbicular is typically obscure but the reniform is usually fairly large, pale, and possessing a fuscous central lunule. The hindwings are similarly luteous but often paler and with more diffuse fuscous lines. Overall, the luteous ground color is similar to that of Idia laurentii, but the lines in that species are less dentate and it lacks the dark medial shade.
Wingspan: 28 mm (Forbes, 1954)
Adult Structural Features: Belongs to Forbes' subgenus Pseudaglossa, characterized by long palps -- reaching the vertex -- and with the third segement very long, conical, and smoothly scaled (Forbes, 1954).
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
