Insects of Australia and New Zealand - R. We discussed the dragonflies reproduction in this page.Īustralia - CSIRO, Division of Entomology, Melbourne University Press, 2nd Edition 1991, Reproduction Reproduction in dragonflies is most unusual and its evolution is a Old male Its broken wings show that it had been fighting with other males many They are found resting or flying amount the low Matured male Matured males have the powder blueīody colour. Usually they are found hunting over the bush a few hundred metersĪway from the waters. Maturing male with colour changing Its body will turn to light powder blue when Teneral male The males just emerged, or the teneral males, have the Following is an example of maturation of the male Blue Skimmer.Īlthough this species is common, sometimes we found confusing in recognizingĬolours when from just emerged to matured. Matured, some will even return to their place of emergence. For those immature adults, they usually hunt inīush far away from the waters. Maturation Maturation of most adults dragonflies takes up to two weeks or less.ĭuring this period the colours of the dragonflies, especially the male,Ĭan change dramatically. The pale green colour helped it hiding among Before this, the youngĭamselfly was quite vulnerable. their body would be harden and turn intoĪdult colours within hours. Its body was weak and could not fly properly. The second picture shows a Easternĭart damselfly had just emerged from last moulting. First picture shows a newly emerged Blueīody is soft and the body colour is not normal yet. Water, just emerged and becoming an adult. The above picture was taken early in the morning, the Australian Emerald Dragonfly nymph came out from Most species emerge during the night to early in The adultĬomes out from the split of the larval skin at the thorax. Plants where it prepares for the final stage of metamorphosis. Which is about 2 meters from the water edge.Įmergence When the larva is fully developed, it moves to the exposed rock or We found this moulting skin (1st picture) on a broken tree trunk On species, while adults live only one to three months. Near the creeks and ponds we usually found thoseĮxuviae, the moulting skin left after the larva climbed up from the water and emergedĪs an adults. Larvae may spend one to three years in water, depend Molting, the larva climb up from the water and emerge from the last molting skin. Small animals such as mosquitoes larva. They capture prey by thrusting The larvae are predator in water preying on Damselfly larvae 20mm Dragonfly larvaĭragonfly larvae breathe by internal tracheal gills and do not have external Comparing with dragonfly larvae they are slender. Damselfly larvae use its caudal gills (the three Some species may wait for the season and survive the winter inĭragonfly and damselfly larva live in water, grow with aįew times (9-15) of moulting. Eggs may or may not hatch immediately, depends Round in shapes, with creamy white in colour. Female layingĭragonfly eggs in a fish-tank Dragonfly and damselfly eggs are elongate, oval to Lay eggs in wet soil and some lay eggs in tree holes with water. Some species insert eggs in plants while other just drop onto water. Prefer running waters such as creeks and streams. Some species prefer still waters such as lagoon and ponds. In the final stage the larva comes out of water andĮggs Dragonfly and damselfly larvae need fairly precise habitat and sensitive to water Larva live in water, grow with aįew times of molting. Dragonflies have three development stages, eggs, larvaĪnd adult. Their larvae look very different fromĪdults but they do not have pupa stage. In-complete metamorphosis nor complete metamorphosis.
