    Neominois ridingsii: Brief Summary
    provided by wikipedia

    Neominois ridingsii, or Ridings' satyr, is a species of butterfly in the family Nymphalidae. It is found from southern Alberta, Saskatchewan and Manitoba south to the Guadalupe and Catron counties of New Mexico, and west to the central Sierra Nevada of California and central Oregon. The habitat consists of short-grass prairie, intermountain areas and grasslands with some areas of bare soil.

    The wingspan is 38–56 mm. The upperside is gray with cream-colored patches across both wings. The forewing has two black spots. The underside is similar but lighter. Adults are on wing from June to July in one generation per year. Adults seldom feed, but if they do, they favor nectar of yellow composites.

    The larvae feed on Bouteloua gracilis. Third- and fourth-instar larvae overwinter.

    North American Ecology (US and Canada)
    provided by North American Butterfly Knowledge Network
    Meominois ridingsii is resident in the western/central United States and south western Canada (Scott 1986). Habitats are prairie, open woodland, and sagebrush. Host plant is the grass species Bouteloua gracilis. Eggs are laid on the host plant or other plants and shrubs singly. Individuals overwinter as third and fourth instar larvae. There is one flight each year with the approximate flight time June 1- early July at low altitude, July 15-early Aug. at high altitude (Scott 1986).
