Dragonflies and damselflies both belong to the order Odonata. All odonates share certain characteristics, including membranous wings, large eyes, slender bodies, and small antennae. Conversely, there are clear differences between dragonflies and damselfies, outlined in the table below.
Knowing whether the odonate you've observed is a dragonfly or a damselfly will aid you in identifying the insect. For most people, learning the most obvious differences – eyes, body, wings, and resting position – will be sufficient. More serious students of the odonates will want to examine the subtle differences in wing cells and abdominal appendages.
