The commonest and most widespread Gomphus in much of our area. It is darker than all other species, with a greener ground colour and more extensive black markings.

Total: 45-50 mm.
Abdomen: 33-37mm.
Hindwing: 28-33 mm.

Habitat

Middle and lower sections of rivers and streams. Favours a calm flow and sandy bottom, avoiding small, fast-flowing, rocky-bottomed waters. Locally abundant in reservoirs, gravel pits and large lakes. The larvae burrow in fine sand, preferably covered with detritus.

Flight Season

From May to August. Typically emerges in great numbers in a short period in spring, followed by a short flight season.

Range and Status

Relatively rare in Denmark.
