Field Guide Descriptions: Covell (1984)Online Photographs: MPG, BugGuide, GBIF, BOLDTechnical Description, Adults: Walker (1856); Edwards (1888)                                                                                 
Adult Markings: Forewings are creamy white to ashen gray with light brown tinting proximal to the inner and outer margins. There is a variable number of jagged black lines connecting the veins. The most prominent markings are a black crescent near the apex and a vertical black line at the base. Thoracic hump triangular and prominent. Typically rests with abdomen curled upward, well above the wings. Length from tip of head to apex of forewing at rest averages 22 mm (n=1). Larvae: The larva remains undescribed (Covell, 2005), but it is highly suspected that larvae bore into trees like those of other members of this family.
