A Brief Look at the Dragonfly Transformation

The dragonfly begins its life as an aquatic larva also called a nymph. Dragonflies live in ponds and calm areas of rivers and streams. While in this larval form, the dragonfly is a predator, feasting on mosquito larvae, aquatic insects, small fish and worms. As the nymph grows and develops it molts by shedding its outer skin called an exuvia. Some species go through as many as 17 molts while in this stage, which can take up to 3 years.

Once a nymph is fully grown and the conditions are right, it crawls up on the stem of a plant and sheds its “skin” one last time.

This molt takes about three hours, and the newly emerged adult dragonfly (known as a teneral) takes to the air with its new wings. It leaves behind its discarded shell which you may find still clinging to a stem long after the dragonfly has flown off.

Adult DragonflyLike the larval form, the adult dragonfly is a predator. It likes to eat mayflies, gnats, mosquitoes and other small flying insects. The dragonfly is a voracious eater. It can consume its weight in food in about 30 minutes.
