Hydropionea fenestralis
Hydropionea fenestralis is a small crambid moth described in 1914, with forewings 12–15 mm in length. Adults display a distinctive reticulated wing pattern and are active from May to October. The species was long considered a mystery regarding its larval biology until 2023, when researchers documented it as a seed borer in Agave salmiana fruits in central Mexico—an unusual host association given its phylogenetic placement in Glaphyriinae. The moth occurs in mountainous regions of the southwestern United States and Mexico, with confirmed records from Arizona, Mississippi, Durango, Veracruz, and Puebla.
Nudorthodes molino
Nudorthodes molino is a small moth in the family Noctuidae, first described in 2014. It is endemic to the southwestern United States, occurring in southeastern Arizona and southwestern New Mexico. The species is named after Molino Basin on Mount Lemmon, Arizona, where most type specimens were collected. Adults are active during two distinct periods: late spring (May–June) and late summer through early autumn (August–November).
Pseudohemihyalea splendens
A medium-sized moth in the family Erebidae, described by Barnes and McDunnough in 1910. Adults are active from late July through mid-November and are found in the southwestern United States and Mexico. The species is notable for its relatively narrow geographic range centered on the Madrean sky islands and adjacent Mexican highlands.
