Dusky Clubtail (Gomphus spicatus)

A common clubtail found at various lake and stream habitats throughout Wisconsin, especially in June. The club is narrow and barely wider than the abdomen in both sexes. Lance-like yellow spots extend through segment 7, segment 8 has only a small pale spot, and segment 9 typically lacks yellow. In males, the upper clasper has both a side- and under-tooth. In females, the ridge between the eyes is trilobed and convex. The Ashy Clubtail (G. lividus) is extremely similar but the male's claspers have no "teeth" and females have a rounded, concave ridge between eyes. Lancet Clubtail has bigger club with more yellow, especially on segment 9. Also compare with Rapids Clubtail.
