|Male Common Bluetail damselfly|
The wings of most damselflies are held along, and parallel to, the body when at rest. There are also damselfly families in which the wings are held open, as in the true dragonflies (Anisoptera).
Damselflies are also usually smaller, weaker fliers than dragonflies, and their eyes are well separated, by more than their own diameter. Another distinction is that their forewings and hindwings look similar; this is not the case in the true dragonflies.
