Comparison with Similar Species
Similar especially to the allopatric sister species elatella, but generally darker. 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 Yucca elata var. utahensis, Y. baileyi, and Y. angustissima var. kanabensis. Females oviposit into flowers . Eggs are laid just below the ovary surface. The larva feeds on developing seeds. Pupation occurs in a cocoon in the soil.
The species is currently known only from extreme southwestern Utah and from northern Arizona.
