Midland clubtail (Gomphus fraternus)

midland clubtail

Midland clubtail (Gomphus fraternus) is an uncommon, early season, medium-sized clubtail. It is found from early June to late July by moderately to fast flowing rivers and large streams, and by large lakes with emergent vegetation. When the adult hunts it perches on the ground or a rock on a bank or shoreline. It is a very strong flier and often patrols open water far from land.

Clubtails (family Gomphidae) are distinguished by expanded abdominal segments 8 and 9 forming a “club”, clear wings with no dark patches, forewing and hindwing triangles similar in size, and eyes that do not meet at the top of the head. Midland clubtail is identified by the moderate-sized club only slightly narrower than the thorax; lack of a black horizontal stripe on the face; and lack of pale dorsal spots on abdominal segments 8 and 9.
