Prodoxus y-inversusOlle Pellmyr
Wing expanse 11-16 mm. Forewing near white with dark brown bands transecting the wing; bands lighter in the male. The bands form a diagnostic inversed Y in the outer portion of the wing. Hindwing pale brown.
Host, Oviposition, and Larval Feeding Habits
The species is reported from Yucca baccata and Y. schottii (Agavaceae). In both cases, the larva feeds in a gallery inside the fruit, and it eventually creates a hardened pupation gallery. Fruits with many larvae become hardened in their entirety and can remain intact for long periods of time.
Geographic DistributionReported only from southwestern New Mexico, southeastern Arizona and southern Nevada.
In shrubby desert and open forest with a host.
