The mating takes place in land vegetation and lasts about 15 minutes. In tandem the female inserts the eggs into submerged plant material, while positioned on top of floating water plants. The eggs hatch after 3-4 weeks. The larvae overwinter in between water plants and imago-transformation takes place the following spring (1 year).
Distribution:
Patchily N and NE Europe. Also patchily through Russia and Siberia to Kamchatka, including small areas in Kazakhstan, Mongolia and China. In Denmark patchily and scarce throughout Jylland; also on Bornholm.
