After the dragonfly egg hatches, the aquatic larva molts once and then starts hunting — eating almost any living thing smaller than itself! As the larva grows, it will molt numerous times until it matures into adulthood. Most dragonfly species mature into adulthood in one to three years, but some species of dragonflies can live in the water as a nymph (baby dragonfly) for over five years!
