Pronghorn Clubtail

Gomphus (Phanogomphus) graslinellus

The Pronghorn Clubtail is brightly-colored dragonfly with a moderate-sized club. It has a greenish thorax with brown stripes and a black abdomen marked with bright yellow. The sides of the club (the lateral portions of abdominal segments 8 and 9) are bright yellow. The male clasper has a lateral tooth, giving it the shape of a pronghorn antelope horn. It usually perches on open ground at the water's edge. The female is similar to the male. The Pronghorn is similar to the larger Plains Clubtail and to the Sulphur-tipped Clubtail, which has more yellow on the club.
