Dragonflies hatch from eggs looking (mostly) like dragonflies, except that they're smaller and, of course, they don't have wings. The nymphs eat, grow, shed, repeat, until they climb out of their exoskeleton one last time and spread their wings. Here's a good kid-friendly overview.
Among dragonflies, males are more colorful than females.

Living things (yes, even plants) are considered mature/adults when they can reproduce. These dragonflies are doing what adults do.
