The Mountain-mahogany Moth (''Ethmia discostrigella'') is a moth in the Ethmiidae family. It is found from the western United States, south into Mexico. The length of the forewings is 10.4-14.7 mm. The ground color of the forewings is dark gray, overlaid with scattered whitish scales. The ground color of the hindwings is pale gray, becoming whitish ochreous toward the anal area. Adults of the nominate subspecies are on wing from April to September in multiple generations per year in the south. Subspecies ''subcaerulea'' is on wing from March to September, also in multiple generations.〔(A Systematic Monograph of New World Ethmiid Moths (Lepidoptera: Gelechioidea) )〕 The larvae of ssp. ''discostrigella'' feed on ''Cercocarpus ledifolius'' and probably other ''Cercocarpus'' species. The larvae of ssp. ''subcaerulea'' feed on ''Cercocarpus betuloides'' and ''Cercocarpus minutifloru''. ==Subspecies== *''Ethmia discostrigella discostrigella'' (Great Basin area of eastern Oregon and California, east of the Sierra Nevada.
