Description

Wingspan: 54 - 72 mm; body length: 45 - 48 mm
 
The male Banded Demoiselle 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 female has translucent, pale green iridescent wings with a white patch near the tip, and a metallic green body.
 
Males are usually territorial. They court females by opening their wings and performing an aerial dance. They are usually found among mature, slow-flowing streams and rivers, and sometimes canals.
 
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 usually take two years to develop into adults.
