Powdered Dancer

Powdered Dancers are small, blue, damselflies. The dark stripe on the top of the thorax is straight and narrow, and the shoulder strip is unforked and quite narrow except for a wide spot towards the back. Some females look like males, but others are tan where the males are blue.
The male is a dark-colored damselfly that develops extensive pruinosity as it matures. (Pruinosity is a waxy, light-colored substance that builds up on a damselfly's body, obscuring whatever coloration lies beneath.
