Common Clubtail Gomphus vulgatissimus
Syn. Club-Tailed Dragonfly
Local in southern and central finland, usually on small rivers, streams. Favours less rocky and rapid streams as Small Pincertail, often in relatively slow-flowing sand-bottomed rivers. As other gomphids, favours clean waters. Can also breed in large, oxygen-rich rocky lakes. Immatures and males can be encountered very far away from water.
Flight period: June-August
Male. All gomphids share the basic colour scheme, and their eyes do not meet at the top of the head. Petri Metsälä
