Taxonomy
Superfamily: Pyraloidea Family: CrambidaeSubfamily: PyraustinaeTribe: SpilomeliniP3 Number: 801335.00 MONA Number: 5228.10
Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: This species was once considered to be a subspecies of Polygrammodes flavidalis (Munroe, 1958), but is currently treated as a separate species. The coloration and patterning is very similar to that of P. flavidalis (see species account for P. flavidalis), but the transverse lines are often interrupted and dotted along their lengths. A comprehensive study of both forms is needed to determine whether P. oxydalis merits being recognized as a separate species.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larval life history is undocumented, but is presumed to be similar to that of P. flavidalis, with the larvae boring in the roots of ironweed.
Distribution in North Carolina
Distribution: Polygrammodes oxydalis is largely restricted to Florida and West Texas into Mexico. It rarely occurs outside of Florida and presumably due to rare, long-distance dispersal events. It probably is intolerant of freezing conditions. As of 2023, we have a single historical record for North Carolina.
