Australian Emerald - Hemicordulia australiaeFAMILY CORDULIIDAE - EmeraldThis page contains pictures and information about Australian Emerald Dragonflies that we found in the Brisbane area, Queensland, Australia.
The Australian Emerald Dragonflies are medium in size, body length about 50mm. They look very similar to another Emerald species T-Mark Emerald. Their wings colour is different and there is no T-mark on the Australian Emerald face. They can be found in the same place. Because both of them never rest, it is difficult to distinguish between them. Australian Emeralds are long and slender, with black pattern on yellow colour. The black patterns are shiny blue green under the sun. Their eyes and mouth occupy almost all their head with bright green in colour. The second picture was taken early in the morning, the Australian Emerald Dragonfly nymph came out from water and just emerged and become an adult. More about dragonflies life cycle please visit this page. During day time, you can hardly come close to them. The Australian Emerald Dragonfly will fly away long before you come into the two meters distance. Males usually patrols in their territories about half a meter above water. Their favored territories are over small pools of water with a lot of weeds in the water, those pools usually cut off from the main water stream by thick and tall emergent vegetations. The areas are also have an open sky. If you come within their territories and stay motionless, they will come close to you, about two meters, and still in the air to inspect what you are. If they get used to with you, they may fly closer to you. If you disturb them or try to catch them, they will fly up to the sky and disappear for quite a while. They rest at night and usually stay high on top of the tree. To take the pictures of this dragonfly we need good camera, patient and luck.
When they become mature, they fly back to the water. The male are now brightly green under the sun. The eyes are in bright green colour. The male usually flying up and down along the creek to protect their territories. They usually fly about 0.5 to 1 meter over the water, sometime stand still in the air.
