Comparison with Similar Species
Similar especially to the allopatric sister species superficiella, but generally lighter and with broader wings. Genitalia are highly characteristic for identification; a diagnostic key is provided.
Host, Oviposition, and Larval Feeding Habits
The species is known from the capsular-fruited Yucca elata (Y. verdiensis). Eggs are laid just below the ovary surface. The larva feeds on developing seeds. Pupation occurs in a cocoon in the soil.
Western Texas from the Big Bend region, extending across southern New Mexico to southeastern Arizona and the Verde Valley of central Arizona.
