Orthetrum sabina is an oriental species showing a huge range going from Australia, Japan and Micronesia to North Africa. They are even covered in the European Dragonfly Bible by Dijkstra/Lewington because they are found on the Mediterranean coast of Turkey which it includes as part of that region. The common names vary in different theatre: Variegated Green Skimmer in Singapore, simply Green Skimmer in Sri Lanka and Dijkstra’s book gives them the vernacular name of Slender Skimmer in Europe.
These were one of our more frequent finds on our initial trip to Singapore and Cambodia. We have since bumped into a single example in Hong Kong Park in 2017 and a couple of examples in Sri Lanka, 2019.
They don’t really look like most of the other “Skimmers” with which I’m familiar but they are an Orthetrum, nonetheless and show th etypical Orthetrum habit of perching on four legs with teh front legs tucked up behind the eyes.
