Description
female Banded Demoiselle (Calopteryx splendens) perched on a leaf. The Banded Demoiselle (Calopteryx splendens) is a species of damselfly belonging to the family Calopterygidae. It is often found along slow-flowing streams and rivers. It is a Eurasian species occurring from the Atlantic coast eastwards to Lake Baikal and northwestern China. Males are usually territorial, but large numbers can sometimes be found in lush bankside plants and on floating objects. They court females by opening their wings and performing an aerial dance. They are usually found in canals and quiet rivers with muddy bottoms located in open country. Females can lay up to 10 eggs per minute for 45 minutes. They lay in a wide variety of emergent or floating plants, sometimes even submerging to do so.
The eggs hatch after 14 days. The larvae have very long legs and are stick-shaped. They develop over two years, usually. They tolerate muddy water and overwinter buried in mud. When they are ready to moult into an adult, they climb up a suitable reed or plant and shed their skin.
This is a large damselfly with a total length of up to 48 millimetres (1.9 in) and a hindwing length of up to 36 millimetres (1.4 in).
The male has translucent wings which each have a broad, dark iridescent blue-black spot (or band) across the outer part. On immature dragonflies the spot is dark brown. The body can be a metallic blue or bluish green.
The dark wing patch of the male starts at the nodus (the slight dip midway down the upper edge of the wing) but can reach up to the wing-tip in southern races.
In the very similar species C. virgo (Beautiful Demoiselle), the dark starts before the nodus.
The female has translucent, pale green iridescent wings with a white patch near the tip (a pseudopterostigma), and a metallic green body.
