Hindwings light to medium gray. Comparison with similar species Very similar to Prodoxus coloradensis , with which it coexists. This is the only known leaf-feeding Prodoxus species. Oviposition has not been observed, but scars have only been found on the leaf underside. Larvae feed singly or, more commonly, communally in mines parallel with the leaf surface.
Communal mines appear as blotches on the leaf surface.
Pupation occurs in a cocoon insided the larval gallery, and adults emerge through either leaf surface. In open oak-pine forest with Yucca baccata. David Maddison and Wayne Maddison.
