Gomphidae (Clubtails) in the order Odonata (dragonflies and damselflies)


The pronghorn clubtail is one of several members of its genus in our area that are rather hard to separate into species. Specialists usually must have them in hand in order to make solid IDs, because they need to examine minute details of stripes and other markings, as well as details of reproductive anatomy.

Like other clubtails in genus Phanogomphus, the pronghorn clubtail is a medium-sized, rather slender dragonfly with a rather slender "club" on its tail, compared to other members of the clubtail family.
