Apantesis nevadensis, the Nevada tiger moth, is a moth of the family Erebidae. It was described by Augustus Radcliffe Grote and Coleman Townsend Robinson in 1866. It is found in the Pacific Northwest of North America, as well as the inter mountain region and the Rocky Mountain states. In Canada, it is found in Alberta and southern Saskatchewan and Manitoba. The habitat consists of deserts, juniper woodlands and open sagebrush range-lands, as well as open forests.[1]
The length of the forewings is 15–. The forewings are black with off-white bands. The hindwings are variable in color, ranging from red to paler. Adults are on wing in late summer and fall. There is one generation per year.
The larvae feed on various herbaceous plants, including Lupinus species and Viola beckwithii.
This species was formerly a member of the genus Grammia, but was moved to Apantesis along with the other species of the genera Grammia, Holarctia, and Notarctia.
