Apantesis behrii
Apantesis behrii is a tiger moth in the family Erebidae, first described by Stretch in 1872. The species occurs in the western United States from Oregon south through California, with highest abundance in the Siskiyou and Sierra Nevada mountain ranges. It inhabits dry, rocky mountain environments and has a narrow adult flight period from early August to late September. Larvae feed on specific host plants including Lotus humistratus and Amsinckia species. The species was transferred from the genus Grammia to Apantesis based on phylogenetic revision.
Euchaetes zella
Euchaetes zella is a small moth in the family Erebidae, described by Harrison Gray Dyar Jr. in 1903. It occurs in the southwestern United States and is one of approximately 20 species in the genus Euchaetes. The genus is notable for including the milkweed tussock moth (Euchaetes egle), whose biology has been well studied, though comparable details for E. zella remain undocumented.
Nelphe
Nelphe is a genus of tiger moths in the family Erebidae, erected by Gottlieb August Wilhelm Herrich-Schäffer in 1858. The genus is currently treated as a synonym of Eucereon by some taxonomic authorities, including GBIF and Catalogue of Life. Two species have been historically placed in this genus: Nelphe carolina (Little Carol's wasp moth) and Nelphe relegatum. The genus belongs to the tribe Arctiini within the subfamily Arctiinae.
Spilosomina
Spilosomina is a subtribe of tiger moths within the tribe Arctiini of the family Erebidae. Members are commonly known as tiger moths and often exhibit aposematic coloration. The subtribe was formerly classified as the tribe Spilosomini in the family Arctiidae before taxonomic revision. It contains numerous genera, though the complete list remains unresolved due to unassigned arctiine genera.
