Photo taken in the Goudse Hout near Gouda (NL), September 1998

Note: When ovipositing, the female of Erythromma najas descends in the water, following a water plant downwards. She disappears below the surface completely and stays there for minutes. The male keeps holding her and pulls her back out of the water when she's done ovipositing.
