Erynnis meridianus meridianus

Meridian Duskywing

The range of Erynnis meridianus meridianus barely reaches California in the New York Mountains of San Bernardino County. It is much better known from Arizona, where it is widespread, and flies from March to October. The type locality is the White Mountains in Arizona. It also flies in southern Nevada, in New Mexico and Texas, and well into Mexico.
