Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1954)                                                                                 
Adult Markings: The ground color is a very dark smoky brown, almost blackish; dull rather than glossy; and with luteous scales intermixed (Smith, 1893). The orbicular is small and luteous. The reniform is kidney-shaped with a central patch of the dark ground color. A pale, partial basal line is present. The antemedian is black and preceded by a luteous shade; its course is irregular and dentate. The postmedian is similar but is more strongly dentate and followed by a luteous shade. The terminal line consists of a broken series of black bars, followed by a fuscous fringe that is interrupted at the veins by pale streaks originating at larger pale dots located at the base of the fringe. The hindwings are similar in color and pattern to the forewings. The ground color of the hindwings is luteous and dusted with smoky brown and crossed by three pale lines.

Idia scobialis has a similar pattern but has a glossy, black ground color. The markings are a brighter white and more contrasting with the ground color than in laurentii. The terminal area is marked with a series of small white dots that are located above the fringe which is a solid dark gray.
Wingspan: 21-25 mm (Forbes, 1954)
Adult Structural Features: Belongs to subgenus Pseudaglossa, which Forbes (1954) characterized by the possession of long palps -- reaching the vertex -- and with the third segment very long, conical, and smoothly scaled.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
