Description: The Rapids Clubtail is a small blackish clubtail with a narrow club. The abdomen has small yellow triangles at the base of segments 3-7. Segments 8-9 have a large yellow spot on the side. The legs are entirely black. The size range is 42-45 mm (1.7 - 1.8 inches).
Similar species: The Rapids Clubtail is extremely similar to Beaverpond Clubtail (G. borealis) and Harpoon Clubtail (G. descriptus). They should be identified by careful examination in hand or by a specimen. See discussion in Paulson (2011).
North American Range: The Rapids Clubtail occurs in eastern North America from Maine and Ontario south to Tennessee and Arkansas. In Virginia it is recorded from several western counties.
