The Jade Clubtail is a distinctive grayish jade green with abdominal segments 7 to 9 rust-colored. Segment 10 and the claspers are pale yellow. It lacks an abdominal club. The thorax has a brown shoulder stripe and the abdomen is marked with green. It has green eyes and pale legs. The female is similar to the male. The bridge (occiput) between its eyes is straight-edged or slightly notched in the middle. It tends to perch on logs and branches protruding from water near the edges of lakes.

Uncommon. It is a midwestern pond species going east to Indiana, westinto eastern Nebraska and south to the Gulf. Northern Nebraska andIowa are the northern limit for the species. The range barelyoverlaps that of the Horned Clubtail in the NE northeastern part of the state. A Buffalo County record is well west of the other Nebraska records and one of the western most for the species. It is often found perching on the bare shore of a pond, but never more than just a few individuals at a pond. The ruddy abdominal tip would separate it from Horned Clubtail, but not from other clubtails.
