Synlestes weyersii are large damselflies which usually land with their wings spread but occasionally they will slowly close them. The pterostigmas are white or a pinky colour in old specimens.
In suitable habitat they are quite abundant and often seen in groups. If you sit and watch them for a while you may see a couple of males in battle. They physically grasp each other in mid-air and sometimes one or both tumble into the water.
The pattern and colour of the female is similar to the male. She has a large ovipositor which is used to lay eggs into rushes and sedges along the edge of a creek.
I was lucky to see a pair of Bronze needles mating and subsequently the female laying eggs, as this has rarely been recorded. The male guarded the female while she laid.
