The Common Blue Damselfly can be easily mistaken for the Azure Damselfly (Coenagrion puella), but on the back and the thorax, the Common Blue Damselfly has more blue than black; for the Azure Damselfly it is the other way around. The second segment of the thorax has a distinctive spot with a line below connecting to the third segment. Damselflies (suborder Zygoptera) are insects in the order Odonata. Damselflies are similar to dragonflies, but the adults can be differentiated by the fact that the wings of most damselflies are held along, and parallel to, the body when at rest. Furthermore, the hindwing of the damselfly is essentially similar to the forewing, while the hindwing of the dragonfly broadens near the base. Damselflies are also usually smaller than dragonflies and weaker fliers in comparison, and their eyes are separated.
