Prodoxus quinquepunctellusOlle Pellmyr
Wing expanse 12-23 mm. Forewing pure white or with 1-14 small spots, rarely forming streaks. Hindwings ranging from gray to near white, but always darker than the forewing.
Comparison with Similar Species
Some members of the Tegeticula yuccasella complex may be confused with larger individuals of this species. Prodoxus is generally less robust and typically smaller. The female has a far thicker ovipositor than does yuccasella. The male, which has very large valvae, lacks the pollex and instead has numerous blunt spines along the valval edge.
Host, Oviposition, and Larval Feeding Habits
The species utilizes many capsular-fruited yuccas (Agavaceae). Larvae feed inside the inflorescence stalk, and pupation takes place inside the gallery. A few records from fleshy-fruited yuccas were assumed by Frack (1982) to have resulted from mislabelling.
Prodoxus quinquepunctellus occurs throughout the composite range of its capsular-fruited hosts, including areas where the hosts have been introduced. the northern limit is most likely in southern Alberta, Canada, and the southern limit on the Mexican Plateau of northern Mexico.
In desert, grassland, openings in pine or deciduous forest, or coastal chaparral and dunes with Yucca.
