In Nebraska it has been found in the western half of the state.

Notes: These two butterflies have been treated both as subspecies of grynea and separate species. grynea is more olive colored dorsally with white markings in the basal area of the ventral hind wing. siva is generally more cinnamon colored dorsally with the basal ventral hind wing immaculate. Genetic studies continue which may provide evidence of yet a third species in Nebraska. grynea is southeastern in origin while siva is western. They have been expanding their range in the state as cedars proliferate and have now both been found at several locations in the state.
