Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Solis (2010)                                                                                 
Adult Markings: The ground color of the forewings is pale yellowish or tan, without a whitish patch between the reniform and orbicular. A darker marginal shade is present as in bipunctalis but is not located immediately adjacent to the postmedian line (Solis, 2015). The dark spots on the second abdominal segment that characterize bipunctalis are absent in this species.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.

Habitats and Life History
Habitats: The majority of our records come from forb-rich wetlands, including marshes and lakeshores
Larval Host Plants: The larvae appear to be polyphagous, but the hosts are rather poorly documented. Heppner (2003) noted that the larvae feed on False Nettle (Boehmeria cylindrica) and Sweet Potato (Ipomoea batatas) in Florida. However, this species is not listed as a pest of sweet potato in North Carolina by the NC Department of Agriculture (see https://content.ces.ncsu.edu/insect-and-related-pests-of-vegetables/pests-of-sweetpotato). From the habitats where we have found this species, False Nettle and other wetland forbs seem to be the most likely hosts. Tracy Feldman found larvae on two wetland species in North Carolina, Lizard's-tail (Saururus cernuus) and Broadleaf Arrowhead (Sagittaria latifolia).
Observation Methods: The adults are attracted to lights.
