Eremberga leuconips

Distinguished from congeneric species by geographic restriction to Arizona and California, combined with the documented wingspan ranges. The larval host association with Echinocereus polyacanthus may aid identification where this cactus occurs. Specific diagnostic morphological features for separating it from other Eremberga species are not described in available literature.

Wingspan ranges from 27–37 mm in males and 26–37 mm in females. As a member of Pyralidae, it possesses the characteristic elongated labial palps forming a snout-like projection. Specific coloration and wing pattern details are not documented in available sources.

Associated with regions where the larval host plant Echinocereus polyacanthus occurs; this cactus species inhabits arid and semi-arid environments in the southwestern United States.

Documented from the US states of Arizona and California.
