The Plains Emerald is dark overall, but has bright yellow side spots on the thorax, a yellow face and bright green eyes. The abdomen of the male is dark without any obvious markings, but the female's abdomen has yellow side stripes. They feed in sunny openings above creeks.

This Midwestern species has scattered records from Ohio intoWyoming and is rare in Nebraska. It seems to prefer, small, clear, sandy, flowing streams through prairie habitat, and all Nebraska records are from northwestern counties.
