Female Banded Demoiselless do not have the dark patches on the wings, but the wings have a pale green tinge all over. Their bodies are an iridescent pale green colour.
In the air Banded Demoiselles resemble a butterflies with their gentle, fluttering flight. You'll usually find Banded Demoiselles around slow moving areas of water. They are very sensitive to pollution and so their presence is often an indicator of good water quality.
