Species name: Anax guttatus
Anax guttatus is heavy-bodied and an unmistakable common dragonfly of open habitats that is often seen in drains, ponds and swamps. The eyes, thorax and the base of the abdomen are mainly green in colour while the 2nd and 3rd abdominal sections are bright blue and the rest of the abdomen being dark brown with lighter spots. Both sexes are similarly marked. The males are often seen "patrolling" back and fro ceaselessly along big drains and over ponds almost the whole day long and well into the early evening. The female can sometimes be seen ovipositing while clinging to floating vegetation or twigs (this one in my photo was sitting on waterlily pads) and is quite fearless when doing so, which could be quite dangerous at times as she can be quite vulnerable to predators. In fact I had seen one being attacked by a green paddy frog.
This species commonly called the Lesser Green Emperor has a very wide distribution range - from Japan, China, all of Southeast Asia to Micronesia. It is also found in Africa.
