Wing expanse 8-14 mm. Dorsum dark brown, with some white scales. Forewing mostly dark brown with numerous white bands and patches, creating a checkerspot appearance. Hindwings ranging light to medium gray.

Holotype in USNM.

Very similar to Prodoxus phylloryctus, which coexists with it in some areas. Adults have some white scales on the dorsum (absent in phylloryctus), forewing scales are ovoid and broader in the outher portion (parallel-sided in phylloryctus), and the dorsoventral vincular lobes in the male genitalia tend to be quadrate (rounded in phylloryctus).

Throughout the range of fleshy-fruited yuccas in the USA, from the California Mojave desert in the west to central Texas in the east, and from southern Colorado to the U.S.-Mexican border.

Reported from numerous fleshy-fruited yuccas and two capsular-fruited yuccas (Davis 1967). The two latter have been challenged by Frack (1982) as likely cases of incorrect labelling. Larvae mine inside all parts of the floral rachis, and pupate just below the surface.
