The River Bluet is blue marked with black, as are many of our Bluet species. Its thorax is blue with a narrow, tapering black shoulder stripe. The amount of black on the abdomen increases incrementally from segments 2 through 7. The abdomen tip is blue. The females may be pale blue or pale tan.

It is a fairly common western species whose range extends into Iowa but not south of Nebraska or north of southern South Dakota. It is nearly state-wide in Nebraska, except for the southern counties. It is foundin a great variety of small streams, even drainage ditches, andoccasionally in ponds, and in the eastern counties it is frequently found in streams with Familiar Bluet.
