Wonnangatta River

27 January 2012

I spent the day by the Wannangatta River west of Dargo. The water level was lower than in February last year, making it easier to wade around in and chase dragonflies. There were many Unicorn Darners Austroaeschna unicornis about, mainly in the calmer sections of the river.

The rapids were popular with the Southern Riffle Darner Notoaeschna sagittata, the males of which were patrolling the area all day from dawn to last light. In the morning I saw this one perched in the vegetation near the river. I was photographing her at 8:30 as she began warming up when she flew off. Fifteen minutes later I happened to be wading in the river and for the first time for me I observed one of these dragonflies oviposting (laying eggs) — I also noticed the damaged wings were the same as the one I had seen perched earlier. This process takes tens of minutes so I had time to take a video of the dragonfly ovipositing.

Also at these rapids were Southern Cascade Darners Spinaeschna tripunctata, a species I have only previously observed once and at this site. Unfortunately during the morning my battery of my good camera was getting low because I didn't charge it fully the night before so I had that on charge and wandered around for a while with my old camera. It was of course at this point that I saw one ovipositing (the only time I did) so the video I took is of a lesser quality.

There were of course other interesting things around including colorful beetles, thirsty feral bees and native wasps. There were quite a few of these wasps around, perching on the vegetation overnight.
