Female Banded Demoiselle Calopteryx splendens
The Banded Demoiselle is found on rivers, streams and canals with moderate to slow water flow over beds of silt or mud and with plenty of waterside vegetation.
Seasonality / Flight Period
Adults generally fly from mid-May to September.
Mating lasts 1-2 minutes, after which the male will guard his female while she lays eggs into the leaves or stems of aquatic plants.
The eggs take about two weeks to develop and the hatching larvae will live underwater amongst roots or aquatic vegetation, usually for two years. The transformation process from larva to adult is called 'emergence' and the Banded Demoiselle larvae will crawl out of the water to emerge on shrubs and trees.
