Anax guttatus

Anisoptera
Species name: Anax guttatus
Family: Aeshnidae
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.

Orthetrum sabina

Anisoptera
Species Name: Orthetrum sabina
Family: Libellulidae

Most people in Sabah would have seen this very common dragonfly in the compound of houses and buildings both in rural areas as well as in towns, in gardens and parks, on the roadside, near drains and ponds. It is definitely one of the dragonflies that I had played with in my childhood!

It is in fact a very wide-spread species that occurs from North Africa, through the Middle East, India and Sri Lanka to Southeast Asia, to China and Japan, through Indonesia to Australia and Oceania.

This dragonfly's distinctive yellowish-green colour with black markings and a slender abdomen or "tail" make it very recognizable and cannot be mistaken for any other dragonfly of this size. It breeds in drains, shallow ponds and even muddy pools of water. Its common name is the Slender Skimmer.
