Calopteryx haemorrhoidalis is a species of damselfly in the family Calopterygidae known by the common names copper demoiselle and Mediterranean demoiselle.

Calopteryx haemorrhoidalis can reach a body length of about 45–48 millimetres (1.8–1.9 in). The abdomen length is of about 34–43 millimetres (1.3–1.7 in) in males, of 31–43 millimetres (1.2–1.7 in) in females. The length of the wings is of 23–32 millimetres (0.91–1.26 in) in males, of 25–37 millimetres (0.98–1.46 in) in the females.

The males have a dark, metallic shining body, the color of which can be red-violet, golden or copper-colored. On the underside of the last three abdominal segments there red area, the so-called "red lantern" (hence the Latin species name haemorrhoidalis, meaning "blood flow"). The wings of males show a large dark area, while the females have a brown band to the wing tip and a metallic-green to bronze-colored body, with a brown belt on the back.


The flight time of this species ranges from May to September. The males have a characteristic mating dance, showing the abdomen end and spreading their wings wide. The male of this species is territorial, defending sites where females may choose to lay eggs.
