Ashy Clubtail

Phanogomphus lividus

The Ashy Clubtail was moved from the genus Gomphus to the new genus Phanogomphus. Their dull brown and yellow coloration makes them look different than most other species of Clubtails, in the area, which help to identify them, although they are quite similar looking to the Dusky Clubtail
