Nebraska Dragonflies and Damselflies
Gomphus (Phanogomphus) militarus
Hagen in Selys, 1858
The Sulfur-tipped Clubtail (subgenus Phanogomphus) is a striking black and yellow dragonfly. Its thorax is black, with bright yellow-green markings, and its club (abdominal segments 7 to 9) is mostly yellow, becoming rusty in older males. The legs are pale and the eyes are blue. It usually perches horizontally on the ground, logs or vegetation. The female has no club and the sides of her abdominal segments 1 and 2 are yellow. It is similar in appearance to the Pronghorn and Plains Clubtails, both of which are darker.
