Non-European Dragonflies various species in no particular order

This dragonfly, also in Singapore, is either a Pond Adjutant, Aethriamanta gracilis, or the slightly larger Blue Dasher, Brachydiplax chalybea, with a brown flank to its thorax.

The Variegated Green Skimmer, Orthetrum sabina, is native to South and Southeast Asia (this one in Singapore). It is also said to occur in Asia Minor (and European Turkey), where it is known as the Slender Skimmer.

Orange Skimmer, Orthetrum testaceum, in Singapore.

Thanks to Tony Clancy for this unidentified red dragonfly in Indochina.

These damselflies are thought to be the Siberian/Central Asian subspecies of the Common Blue, Enallagma cyathigerum risi. The blue is likely a blue form of female (a little greenish and not a full blue tail) and the other a greenish female, both in southeast Kazakhstan.

Thanks to Alexandra Makhnina for this dragonfly in Costa Rica.
