Nebraska Dragonflies and Damselflies
The Cobra Clubtail is a medium-sized black dragonfly with yellow or green markings and a very wide club. It can be recognized by the lateral yellow spots on its club: small dots on abdominal segment 8 and large ones on segment 9. The bases of the wings are occasionally tinted with yellow. The eyes are green, and the face is yellow with a broad blackish stripe. It is often found perching horizontally on rocks along rivers or in the brush near the water's edge. The female is similar to the male, but with a smaller club and paler markings.
