| General | • a large species which occurs throughout much of Europe; similar to C. splendens but with broader, completely opaque wings | |
| Classification | • suborder: Zygoptera (damselflies); family: Calopterygidae | |
| Conservation status | • IUCN Red List Europe: Least Concern | |
| Scientific name | • Calopteryx virgo (Linnaeus, 1758) | |
| Distribution | • click or tap the Map button above | |
| Notes | • its flight is fluttery and butterfly-like | |
| • males engage in a dazzling display flight to attract females into their territories | ||
| • to demonstrate the suitability of an ovipositing site males sit down on the water and allow the current to carry them by that site while 'flashing' the coloured underside of their abdomen tips at the females | ||
| • both males and females hold territories at the water | ||
| Habitat | • fairly fast-flowing shady streams and brooks | |
| Dimensions | • typical body length: 45-49 mm; hindwing: 24-36 mm | |
| Both sexes | Wings | • the wings are wide, rounded and spoon-shaped |
| Male | Thorax | • the thorax is metallic dark green-blue |
| Abdomen | • the abdomen is metallic dark green-blue | |
| • the underside of the last three segments is yellowish white or, in the subspecies C. v. festiva, reddish pink | ||
| Wings | • the wings lack a (pseudo-)pterostigma | |
| ➤ the rounded wings are almost completely dark blue | ||
| Female | Thorax | • the thorax is metallic dark (brownish) green |
| Abdomen | • the top of the abdomen is metallic dark (brownish) green | |
| Wings | ➤ the rounded wings are opaque and smoky brown rather than translucent green; they bear a white pseudopterostigma positioned rather distant to the wing tip | |

| • the photos we made in Greece show the subspecies C. v. festiva |
