Milgithea alboplagialis
Dyar, 1905
Milgithea alboplagialis is a small snout moth in the Pyralidae, first described by Harrison G. Dyar in 1905. It is known only from the Huachuca Mountains in southeastern Arizona, where it inhabits montane environments. The is characterized by a relatively modest wingspan of 23–27 mm. Like other members of its , it belongs to the Epipaschiinae, a group of pyralid moths whose larvae are generally associated with dead or decaying plant material.
