Another common dragonfly of the Diplacodes genus, is Diplacodes nebulosa. I have seen this species regularly and pretty much all year round, especially at small to large vast lakes with lots of land around.

The mature male
The mature male is completely "powder" blue, This species is distinctive because of its wings. There is a black mark at the end of each wing.

Powder blue...
A close-up of the mature male to demonstrate just how blue the species really goes. You can still make out the markings underneath too!


The young male
This is a younger male which has the same wing patterns and markings, but yet hasn't started to pruinose.



The teneral male
This is a teneral male which has the same thoracic markings, but yet hasn't started to pruinose or have any colour to its wings. It was a very pale and hairy looking thing.




The female
The female is similar to the younger male, but has slightly different markings and the abdomen is more robust.


The teneral female
The female is similar to the adult female, but its eyes are much lighter in colour and has whitish markings along the top of its wings.






A copula
I was lucky to see a copula in the wheel position a few years back, but it's not the best photo ever. I will hopefully get a better one soon.
