For me, this is the king of the 'minis'. Ischnura aurora is only tiny, but his colours scream for attention. The males like to sit in long grasses and are supposed to be common in paddy fields... though I have never seen one in Khon Kaen and its full of paddy fields there!
Green and black stripes on the thorax with a bright yellow abdomen, capped by stunning black and bright blue end segments, make it truly one of the best looking damselflies I've seen.
She's really dull in comparison. She has slight blue hues on the thorax and slight yellowing to the abdomen. The markings on the abdomen are also completely different to that of the male. The females are far more difficult to spot and the one I saw hung far back from the main body of water in the bushes.
Here is a slightly younger female ...
