Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1954); Rings et al. (1992)                                                                                 
Adult Markings: A small, blackish Idia that is very similar in size and color to Idia rotundalis but has more conspicuous white markings on the forewing, with noticeable white spots on the costa marking the beginnings of the transverse lines. The orbicular and reniform are also usually visible as white spots that contrast strongly with the blackish ground color (Forbes, 1954). The hindwing also has noticeable pale lines crossing the dark ground color, but is less strongly banded than in Idia forbesii. The underside of the hindwing is also somewhat banded but less so than in forbesi.
Wingspan: 20 mm (Forbes, 1954)
Adult Structural Features: Belongs to Forbes' subgenus Pseudaglossa, characterized by long palps -- reaching the vertex -- and with the third segment 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].
