Adult Markings: A medium-sized brownish moth often with a distinct black curved line through the median area of the forewing. Likely to be confused with Pseudorthodes vecors (the form lacking a white reniform), Orthodes cynica, and Protorthodes oviduca. H. furfurata lacks traces of reddish coloring and is usually smaller than the other species. Sexes are similar. |
Adult Structural Features: Unlike Protorthodes, the male antennae are fasciculate, not serrate or pectinate. 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 in these genera. H. lindseyi 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 with a small head and swollen posteriorly (see Neil, 1983, for a detailed description and illustrations). Distinguishable from H. lindseyi by structural characters. |
Larvae ID Requirements: Identifiable from close inspection of specimens or by DNA analysis. |
