Odontiinae
Odontiinae is a subfamily of moths in the family Crambidae, containing approximately 100 genera organized into three tribes: Hercynini, Eurrhypini, and Odontiini. The subfamily exhibits a distinctive biogeographic pattern with exceptional diversity in arid and semi-arid regions, particularly in southwestern North America and western/central Asia. North American species show strong southwestern eremic specialization, with 34 of 57 species restricted to arid habitats, contrasting with depauperate eastern faunas. The group includes both widespread temperate species and highly restricted endemics in alpine and desert environments.
