Field Guide Descriptions: Covell (1984; described as a subspecies of H. furfurata but not illustrated) | Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD | Technical Description, Adults: Forbes (1954) | Technical Description, Immature Stages: Forbes (1954); Crumb (1956) | |
Adult Markings: In size and shape very much like H. furfurata. However, that species is brown while H. lindseyi is a reddish/pink color and has pearly hindwings instead of the fuscus ones of H. furfurata. It is smaller than most Pseudorthodes cynica and Orthodes vecors and their reddish coloration is a different tone and darkened with blackish scaling. |
Adult Structural Features: The male genitalia are readily distinguished from those of Orthodes, Protorthodes and Pseudorthodes by the expanded distal end of the valves. Female genitalia are also different. H. furfurata has very similar male and female genitalia, but the males may be differentiated by the shape of the distal end of the valves. Females are more difficult to distinguish using genital characters. |

Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: Larvae are blackish-brown, with small heads and swollen posteriorly; very similar to those of H. furfurata but can be distinguished based on structural characteristics (see Crumb, 1956). |
Larvae ID Requirements: Identifiable from close inspection of specimens or by DNA analysis. |
