Female damselflies (and some dragonflies) have well-developed ovipositors used to insert eggs into plant tissue.
(some dragonflies the ovipositor valves are reduced, and eggs are dropped into water)

Both male and female have caudal appendages at last segment of the abdomen (segment 10), which in males work like claspers to grasp the female during mating.
