Calopteryx virgo (Odonata - Calopterygidae) is an European damselfly, commonly known as Beautiful Demoiselle.

In this species the wings of the mature male are very dark blue-black and those of the female are iridescent brown-green. The body colour is metallic blue-green in the male and green with a bronze tip in the female. The flight is fluttering, butterfly-like [source].

As a welcome to the new (and old) followers of my blog: a Familiar Bluet with surprised face.

Its scientific name is Enallagma civile and is a damselfly of the family Coenagrionidae (order Odonata) that is common and widespread in America. Although the photo does not show the body, Enallagma civile is a tiny damselfly, up to 39 mm. Males are light blue with black bands and stripes and females are quite variable [1].
