Dragonfly Life Cycle

Dragonflies can live up to a year. However, they don’t spend very much time as an adult dragonfly. They spend most of their time in the larval stage.

Eggs

Female dragonflies lay their eggs near or in water. The female dragonfly will lay its eggs on a surface such as a plant or even in the water.

Larva

Next, the eggs hatch into dragonfly nymphs. Nymphs are considered baby dragonflies. In the nymph stage, the baby dragonfly stays under the water and eats aquatic insects, mosquito larvae, and small fish. Nymphs do not have wings. The larval stage of large dragonflies may last as long as five years. For smaller species of dragonfly, it may last anywhere from two months to three years. When it is time for the dragonfly larvae to change into an adult it climbs out of the water. It starts to breathe the air.

Adult

The adult forms when the nymph is fully grown. Next, the skin splits behind the head and an adult dragonfly crawls out. The adult stage lasts a just a few months and then the cycle begins again. The adult dragonfly mates and then the female dragonfly lands and lays eggs.
