Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: A large underwing moth. Fore-wings have a flat yellowish or grayish-brown ground color but with a pale gray sheen that is more or less evident depending on the lighting and angle of view. The typical form (nurus, according to Holland, , and Forbes, 1954) has a heavy dark basal dash that usually is joined with a median and apical dash that crosses the wing diagonally; in form selecta, the dashes are reduced or absent (Sargent, 1976). The antemedian and postmedian lines are dark and contrasting in the upper half of the wing but paler towards the inner margin; the upper portion of the antemedian is fairly wavy and runs obliquely in from the costa (less smooth and curved than in cara and carissima) and often has an inward-pointing tooth at or near the radius (an outward tooth is usually prominent in cara and carissima). A large sub-reniform spot is present and usually joined to the antemedian by a dark patch or lines (Sargent, 1976). The hindwings are strongly marked with red and black bands, similarly to cara and carissima, but lack the black basal area present in those species.
Wingspan: 75-85 mm (Sargent, 1976); 89 mm in one of our specimens
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].

Habitats and Life History
Habitats: Our records come mainly from wetland habitats, including several where either Eastern Cottonwoods or Swamp Cottonwoods are known to occur. However, it has also been recorded at some sites where only willows are known. It has also been recorded on some high ridges in the Mountains where neither willows nor cottonwoods seem likely to be present; Bigtooth Aspen has been recorded at least at one of those sites, however.
Larval Host Plants: Larvae reportedly feed on poplar (Populus spp.), including cultivated species, and possibly willows (Wagner et al., 2011). - View
