Behaviour
On a sunny winter day, this damselfly may be the only damselfly still flying over the water, even though a few of them can be seen. In the summer, a large number of Blue Riverdamsels are competing for a good perching position with other damselflies.
After mating, the female will return to the water and lay her eggs, usually with the male still in the tandem position. They lay their eggs in the plants under the surface of water. Females have a blade-like ovipositor for making an opening in the plant for her eggs. They will sometimes lay eggs alone without the male in tandem position. (Wikipedia)
