Development takes longer in cooler waters where food is scarcer whilst in warm waters there may be a new generation every year. Extract from Secrets of PilanesbergExtract from Secrets of PilanesbergA wonderful example of MetamorphosisThe nymph lives under water for 4 years Some.
Dragonflies lay their eggs in water and when the larvae hatch they live underwater for up to two years.
How long do dragonflies live in water. Dragonfly nymphs live in the water while they grow and develop into dragonflies. This portion of the dragonfly life cycle can take up to four years to complete and if the nymph cycle is completed in the beginning of the wintertime it will remain in the water until spring when it is warm enough to come out. At the shortest the life cycle of a dragonfly from egg to the death of the adult is about six months.
There are even dragonflies that live for several years as aquatic larvae before they emerge and live for a few months as adults. Most dragonflies dont die of old age but are caught by predators. Some species of naiads can live in the water for four years if conditions are right.
The adult stage when the dragonfly takes wing is shorter. The adult dragonfly probably lives six or eight weeks at the most although the Variegated Meadowhawk Sympetrum corruptum among others may overwinter. Dragonflies begin their lives in the water.
Around midsummer females hover over bodies of fresh water and dip in their abdomens laying eggs that hatch in about seven to eight days. About 300 million years. Huge dragonflies with wing spans up to 30 inches were flying when dinosaurs roamed the earth.
Where do dragonflies live. Dragonflies start their life in water therefore they are often found near water. Ponds lakes canals streams rivers and swamps.
Larval development typically takes one or two years but ranges from 23 months emerald damselflies to more than five years Golden-ringed Dragonfly. Development takes longer in cooler waters where food is scarcer whilst in warm waters there may be a new generation every year. Dragonfly Nymphs Live In the Water.
Theres a good reason why you see dragonflies and damselflies around ponds and lakes. Female dragonflies deposit their eggs on the waters surface or in some cases insert them into aquatic plants or moss. Once hatched the nymph dragonfly spends its time hunting other aquatic invertebrates.
They can be found anywhere but typically live near shallow freshwater such as ponds streams lakes and wetlands. They have a short life span Dragonflies have a short life. Dragonfly nymphs live in the water.
As they grow they molt shed their skin. Nymphs of some species may take as long as three years to mature. 9 Some adult dragonflies live for only a few weeks while others live up to a year.
10 Nearly all of the dragonflys head is eye so they have incredible vision. Some of the larger dragonflies take 6 or 7 years. Most of this time is spent in the larval form beneath the water surface catching other invertebrates.
The small damselflies live for a couple of weeks as free-flying adults. The larger dragonflies can live for 4 months in their flying stage. Andy Muir Flickr Mated dragonflies and damselflies deposit their eggs in on or near the water depending on the kind of odonate.
Most odonate species are endophytic ovipositors meaning they insert their eggs into plant tissues using well-developed ovipositors. The female typically slits open the stem of an aquatic plant just below the waterline and places her eggs inside the stem.

During their short life spans which range from a couple of weeks to a couple of months they will travel in search of resources and changing environmental factors. Some dragonflies like the green darner can travel around 7 and a half miles each day whereas the globe skimmer can travel an impressive 11000 miles over the Indian ocean. Dragonflies lay their eggs in water and when the larvae hatch they live underwater for up to two years.
Actually depending on the altitude and latitude some species may stay in the larval. Where Do Dragonflies Live. Dragonflies can be found all over the world.
They typically stay close to water. Most species of dragonfly spend the majority of their life underwater or close to the surface of the water. Depending on the species dragonflies prefer ponds marshes or streams.
