Calopteryx haemorrhoidalis (Vander Linden, 1825)
Copper Demoiselle
Type locality: Lazio, Italy
Diagnosis
A stunning demoiselle, easily identified by the carmine ‘tail-light’ of the male and dark apical Hw spot of the female. Typical males are unmistakable by their reddish bronze body and largely dark wings, which appear dark brown (in stead of blue) when closed and have a conspicuous clear area at base. The demarcation of the clear base is notably oblique because the coloured area runs almost to the wing base anteriorly. Locally males appear brown, purplish, dark blue, olive or almost black. This colour is always darker and duller than the bright green to blue of C. exul and C. virgo, while the wings appear brown to black, not blue. Males have the underside of the abdomen tip uniformly bright pink to vivid red. The metallic green to bronze females are unmistakable by the contrasting dark Hw tips, and unlike other females have narrow pale humeral lines. In both sexes the tibiae are frequently rusty brown (black in other Calopteryx). [Adapted from Dijkstra & Lewington 2006]
