16 Oct dragonfly life cycle
Slowly, the adult emerges from the cast skin (called the exuvia) and begins to expand its wings, a process that may take an hour to complete.
In some species, eggs may hatch in just a few days, while in others, the eggs may overwinter and hatch the following spring. In the coldest regions of their range, dragonflies may remain in the larval stage for several years. Dragonflies pull water into their rectums to respire. In dragonflies and damselflies, a prolarva hatches from the egg and quickly molts into the true larval form. The female typically slits open the stem of an aquatic plant just below the waterline and places her eggs inside the stem. The eggs sink to the bottom or fall onto aquatic vegetation. Dragonflies that oviposit directly into the water may produce thousands of eggs. The new adult will be weak and pale initially and only have limited flying ability. Initially, the dragonfly is out for hunting their respective mating partners.
There are two methods for depositing eggs: flying lo…
When it is finally ready for its last molt, the larva crawls out of the water and grabs hold of a plant stem or other surface. Some nymphs travel quite far from the water.
Dragonfly eggs are only laid in still water, as eggs laid in quickly moving water will wash into fish-feeding areas. Teneral adults are more vulnerable to predators, as they have softer bodies and weaker muscles. Mated dragonflies and damselflies deposit their eggs in, on, or near the water, depending on the kind of odonate. Life cycle of a dragonfly is divided into three simple stages: the egg, the nymph and the adult. What Do Adult and Immature Dragonflies Eat? Like adult dragonflies, the nymphs are predators.
Some species lie in wait for prey and hide by either burrowing in the mud or resting within the vegetation. Damselfly nymphs swim by undulating their bodies.
After breeding, a female dragonfly selects a pond or marsh in which to lay her eggs. Having reached sexual maturity, this new generation will start searching for mates and begin the life cycle again. Endophytic ovipositors include all damselflies, as well as petal tail dragonflies and darners.
All dragonfly and damselfly nymphs are aquatic and remain in the water until they are ready to molt into adulthood. During this aquatic stage, odonate nymphs breathe through gills. This is called a teneral adult. Their young are aquatic, and they require water to complete their life cycle.

Dragonfly larvae are also called nymphs or naiads. All dragonflies and damselflies (Order Odonata) undergo simple or incomplete metamorphosis. Other species hunt actively, sneaking up on prey or even swimming in pursuit of their meals. After mating the female dragonfly carries her eggs and gently places it on still water as running or moving water might wash away all the eggs to fish feeding areas. Dragonfly conservationists are concerned that manmade objects may be putting some odonates at risk of decline because female dragonflies have been known to deposit their eggs on solar panels or car hoods instead of in ponds or streams. These dragonflies deposit their eggs on the water's surface, or in some cases, on the ground near the pond or stream. Sometimes the eggs are injected directly into stream or pond sediment.
Life Cycle and Biology.
Female dragonflies, like hawkers and darners, lay endophytic eggs. Once the dragonfly leaves the exuvia it is a full grown dragonfly. Damselfly gills are located at the end of the abdomen, while the gills of dragonfly larvae are found inside their rectums. In warmer climates, the larval stage may take only a month, with the nymph growing rapidly. In exophytic ovipositors, the females extrude eggs from a special pore on the underside of the abdomen. Their hunting methods vary.
Once the dragonfly finds a mate, the female will find a body of calm water that will be a good place to lay her eggs, and the life cycle of the dragonfly begins all over again. The dragonfly will hunt for food and begin to look for a mate. In some species, the female will briefly submerge herself in order to oviposit in a plant well below the water's surface.
The Golden-ringed Dragonfly lays its eggs by hovering vertically and stabbing its abdomen into stream-beds. Egg hatching varies considerably. The life cycle of a dragonfly starts with eggs.
Some dragonflies are exophytic ovipositors.
Within a few days, the dragonfly or damselfly usually exhibits its full adult colors and gains the strong flying ability that is characteristic of odonates. This means that scythe-like ovipositors are used to inject these elongated eggs into plant stems, leaves, rotten wood, or debris that is at or near the surface of a water source. Exophytic ovipositors include clubtails, skimmers, emeralds, and spiketails. Animals & Nature. The closer to adulthood the nymph is, the fuller the wing pads appear. Some species fly low over the water, dropping eggs at intervals into the water. Once out of the water and secured to a rock or plant, the nymph expands its thorax, causing the exoskeleton to split open. During the final few instars, the dragonfly nymph begins to develop its adult wings, although they remain tucked inside wing pads. Insects Basics Behavior & Communication Ants. Dragonflies and damselflies aren't zipping about the pond to enjoy the scenery, though. If the prolarva hatches from an egg that was deposited on the soil, it will make its way to the water before molting. Other dragonflies, like emeralds, skimmers and clubtails, extrude round exophytic eggs from a special pore on the underside of their abdomens.
They live near water for a reason.
