Calopteryx virgo (Linnaeus, 1758)
Type locality: Germany, no locality data available.
The largest and darkest Calopteryx, with (almost) entirely metallic cobalt wings in males and transparently greenish to deep ebony wings in females. Wings, especially male Hw, broader than in other Calopteryx, almost paddle-shaped. Male wings appear completely purplish blue (but see variation). His ‘tail-light’ (underside of abdomen tip) is brown to reddish, extensively marked with black (paler or unmarked in other species). Females are metallic (brownish) green and may be hard to separate from C. exul, but the wings tend to be broader and browner (sometimes very darkly so). [Adapted from Dijkstra & Lewington 2006]
Streams and headwaters in open areas in forest or shaded by gallery forest. Often with emergent and aquatic vegetation, submerged roots, coarse detritus and/or rocks. Inferred to occur from 100 to 600 m above sea level, but possibly up to 1800.
