Was photographed at the same spot as the Trithemis Aurora & seemed to be interacting with them - both species were perched very close to one another by a small stream.
Keith Wilson replies: Mature female Trithemis aurora. It is not unusual for long-lived mature females to change to male colouration albeit only a hint in many cases.
EG: I guess this explains your observed "interactions" :-)
Pseudagrion microcephalum is becoming more regularly seen at Mai Po. This individual was seen perching in rehabilitated freshwater pond in the reserve.
I used a 20X telescope, home-made adapter and Ricoh GX camera set at self-timer to take the picture.
Lau Shui Heung is one of the serval known locations where this species can be found in Hong Kong.
The dragonfly was perching on boulder of a small stream when spotted.
