Behaviour

Males are not very territorial, with large numbers being present at some sites. Males hover over emergent vegetation, seeking females to mate with. They will frequently settle, especially on open ground and stones. In hot weather they will rest in the obelisk position, with abdomen pointing upwards, to reduce the surface area presented to the sun. Copulation lasts for several minutes, with oviposition taking place in tandem or alone. Oviposition takes place either directly into water, or into mud and mats of vegetation. Larvae emerge after one year and can survive the temporary drying out of their habitat.

Habitat

Mainly heaths containing boggy pools, peaty ponds and lakes with abundant emergent rushes and sedges. Sheltered sites produce the highest numbers. Sometimes disperses into atypical locations.
