	A female Aethriamanta aethra. A rare species in Sabah, Borneo Island. This is a small dragonfly and the measurement are : Hind wing length =23mm Abdomen length = 16mm Total body length = 26mm Hindwingspan = 48mm Segment 9 pocket full of fertilized eggs. An egg size is about the wide of the lines on the graph sheet that is about 0.2mm
	This female Aethriamanta aethra abdomen is distinctive black on top and yellow marking at the side. Segment 8, 9 and 10 are dark. The eggs in segment 9 are translucent. Look blueyish in this image but greenish to the naked eyes. This female was set free after photography to continue her eggs laying in a weedy pond, as Malaysian nature parks rule ‘TAKE NOTHING BUT PHOTOS’
	Greenish Egg-mass This lonely female Aethriamanta aethra was laying eggs at a weedy pond when found. No male was seen around. I was amazed to see for the first time Green dragonfly eggs. (In the image the egg color look more blueyish) A rare species with rare egg color.
	The two eyes meet along a long seam as compare to most other dragonflies eyes only touch at short seam. Top of thorax is black with yellow marking.
	There was no photo available in Google for quick identify of this insect. Finally with this wing image I traced to the last dragonfly on Page 123 of DRAGONFLIES OF PENINSULAR MALAYSIA AND SINGAPORE by A.G. Orr. Dr Orr’s high precision and detail on dragonfly drawings is greatly helpfull.
