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.
