DSCN1890 sexual dimorphism
Calopteryx Virgo Male, a European Damselfly (beautiful demoiselle resting near river Warta, at the small river Oszczynica mouth). This species presents an evident sexual dimorphism in color pattern (lifetime determined from about 40 to 50 days). Adult males have metallic blue-green bodies, blue-green eyes, and the metallic blue wing color. The male is perching in bankside plants, waiting for females or chasing. At night the animals sit in the vegetation at these sites, often resting and spending the night on herbaceous plants such as the purple loosestrife.
