Welcome to my quick identification guide of the Common Blue Damselfly.
These graphics are meant as a guide to the key identifying features of both the male and the female dragonflies.

The bluest of the blue / black damselflies. The thorax viewed from above bares two broad blue stripes. Just behind the wing roots on the second abdominal segment is a mushroom shaped symbol, the stalk of which may be absent. The upper surface of segments 8 & 9 towards the tip of the abdomen are all blue, often appearing brighter than the rest of the blue areas of the insect.
