Sight is by far their most important sense, used to catch flies and avoid birds. As a result, they have a wide field of vision: they can see almost everywhere at once. Their eyes wrap around the top of the head. Their compound eyes are very large and have up to 50,000 individual lenses. Notice how this dragonfly's eyes wrap all the way over the top of its own head.ĭragonflies have tremendous eyesight. As the exoskeleton cracks open at the seam, the adult dragonfly crawls out.Īdults Eyesight It use this to crawl out of the water, and wait for its exoskeleton to dry. When a naiad is ready for its final moult, it finds a stick or other object sticking out of the water.

Naiads live in the water for weeks (or even years in some species) and undergo a series of moults to grow. Some naiads even have a long lower jaw that can shoot out and grab prey. This moves the naiad forward very quickly, allowing it to snatch its prey with its powerful jaws. It can then squeeze water out of the rear of its abdomen like a jet stream. Hidden among the plants, a naiad will lie in wait for prey to swim by. While living in the water, the naiads eat as many aquatic insects as possible, as well as other small creatures like tadpoles and minnows. The naiads – which do not look much like dragonflies at all – hatch and immediately take to the water. The female dragonfly lays her fertilized eggs near or right in the water. The adult stage of larger species of dragonfly can last as long as five or six months.ĭragonflies experience incomplete metamorphosis: the nymphs (called naiads) swim and live underwater, like fish.

The skin splits at a weak spot behind the head and the adult dragonfly crawls out of its old larval skin, pumps up its wings, and flies off to feed on midges and flies. Exposure to air causes the larva to begin breathing. When the larva is ready to metamorphose into an adult, it climbs up a reed or other emergent plant. In smaller species, this stage may last between two months and three years. The larval stage of large dragonflies may last as long as five years. They can move fast by squirting water out of the anus. They draw water in and out of their rectum.

Tiny vertebrates such as tadpoles and fish are part of its diet. It can extend its jaws in front of its mouth to catch prey. Most of a dragonfly's life is spent in the nymph form, beneath the water's surface. While in the nymph stage they eat mosquito larvae and other things. When laying eggs, some species go under the water to lay their eggs on a good surface. Taken together, these points are usually enough to distinguish the two groups.įemale dragonflies lay eggs in or near water, often on plants. Many damselflies live in groups close to a river. The eyes of dragonflies are larger, and touch each other. Most dragonflies hold their wings horizontally.

When at rest, most damselflies hold their wings together above the body. This you can see even when they are flying. Some people mistake the damselfly for the dragonfly, because they look similar.Īdult damselflies have thinner, more delicate bodies than those of dragonflies. Oxygen levels were quite high at that time.ĭragonflies and damselflies ĭragonflies are in one suborder of the Odonata, and their relatives, the damselflies, are in another suborder. In the rain forests of the Carboniferous and Permian periods, some species had wingspans of over 2 ft (61 cm). Once they perch, they rarely use their legs for walking.ĭragonflies have been around for 300 million years. They are also carnivorous.īecause their legs are adapted to grab prey in the air, they are not adapted for moving on land. Their larvae, known as 'nymphs', are aquatic.

They are predators which eat mosquitoes, and other small insects such as flies, bees, ants, and butterflies. They have four strong transparent wings, and a long body.ĭragonflies are usually found around lakes, ponds, streams and wetlands. ĭragonflies have large compound eyes, which is their main sense organ. There are about 5,300 species of dragonfly. Dragonflies are flying insects of the order Odonata.
