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.
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.
In shrubby desert and open forest with a host.
