The Riverine Clubtail is a member of the Stylurus, or Hanging Clubtail, genus. These clubtails perch on leaves, which tip with their weight, leaving the dragonflies hanging nearly vertically. The Riverine Clubtail is small and has a vivid black and yellow pattern, including a three-pointed star on the top of the thorax. The face is variably mottled black, and the eyes are dark green. Abdominal segments 8 and 9 have large yellow spots on the sides. The female is yellower than the male.

Uncommon. This is a midwestern species with records east to the Atlantic and west across two-thirds of Nebraska. Sometimes it is common as emergingtenerals on grassy backs banks of rivers and streams.
