Another widespread river-dwelling damselfly that is simply divine, is Aristocypha fenestrella. I have seen this species at several rivers and streams throughout Thailand and it loves sunny areas, where there are lots of boulders in the river. 

The male

The male is simply beautiful. Once it is fully mature, it has lots of metallic colouration to its wings. Sometimes, a green tinge when younger which goes more of a blue/purple as it matures. They really are beautiful to look at. Not surprising, really, that its nickname is Peacock Jewel.

The female

The female is far less interesting to look at and is dull in comparison. The females are often confused with other similar species, but I think the markings on the female are quite distinct. Also, the wings are brown in colour.

You can find this species throughout the country all year at upland and some lowland rivers. Look for big boulders and rocky areas where the sun is bursting through the tree canopy. You're sure to find them there.
