Normally one of the easiest ways to tell a dragonfly from a damselfly is the size.  Dragonflies are usually thicker-bodied and much larger.  Usually.  One lovely exception is the Red Dragonfly which, at barely more than 25 mm long, is one the smallest dragonflies in the world (less than half the size of the damselfly described under the letter D).  

These tiny hunters (and their close relatives) are found in wet heathlands and swamps both in Australia and South-east Asia.  Like damselflies, the adults hunt in the air catching flying insects on the wing while the juveniles hunt under water catching small aquatic animals.
