Banded demoiselle vs Beautiful demoiselle
These two are easy to mix up. Here's how to tell a banded demoiselle from a beautiful demoiselle, and whether either one bites or stings.
Banded demoiselle
Calopteryx splendens
Beautiful demoiselle
Calopteryx virgo
≠The key differences
Male C. virgo usually has darker, more extensive wing coloration often covering most of the wing and a darker, bluer body; habitat often in shadier, faster-flowing streams. C. splendens usually has clearer wing tips and a slightly different wing band shape.
Male C. splendens has a clear wing base with a dark band near the tip; male C. virgo has wings that are broadly and more uniformly dark. Body coloration and habitat overlap but wing pattern distinguishes them.

🔍How to spot a banded demoiselle
- Males: metallic blue-green body with a broad, continuous dark band across the middle of each wing, leaving clearer tips.
- Females: metallic green body with translucent greenish wings, no dark band, and a small white spot near each wingtip.
- Broad wings held closed above the body at rest (typical damselfly posture) and larger, more robust form compared with narrow-winged damselflies.
🔍How to spot a beautiful demoiselle
- Males: metallic blue-green body with broad, uniformly dark iridescent wings (often blue-violet in sunlight).
- Females: metallic green body with translucent smoky-brown wings and a white spot near each wingtip.
- Large size for a damselfly and broad wings (family Calopterygidae) compared with narrow-winged damselflies.
- Frequent presence along shaded, fast-flowing streams with overhanging vegetation.

Identification from photos is never certain: don't handle insects you can't identify, and get medical advice for bites, stings or allergic reactions.
