Eggs are not laid, but broadcast from the air: the male holds the female in tandem and swings her down and forward over water. At the furthest point of the arc the female releases some of her eggs to fall on the water.

Eggs are laid on the wing, or from brief perches on grass stems, and are just sprinkled among the grass stems. Upon hatching, the larvae immediately enter hibernation and only feed the following spring when the fresh growth occurs. They are a lime-green colour, with a dark green line running down the middle of their back. Pupation takes place at ground level in a loose cocoon. Adults can be found from early June to early September. On a good site, in warm, sunny weather, thousands can be seen gently fluttering amongst the grass heads.

Female Banded Agrion (Calopteryx splendens)

Male and female are variable in color and pattern. The male has translucent wings which each have a broad, dark iridescent blue-black spot (or band) across the outer part. On immature dragonflies the spot is dark brown. The body can be a metallic blue or bluish green or a combination of both colours, depending on the time of year and location.
