Hi LK
A very nice photo thanks for sharing it with us
This dragonfly is one of the dropwing family (Trithemis) but to ID it you would have to see if there are any distinctive markings on the body and if not then it is a case of counting certain cells in the wings, an comparing the pterostigma (that dark patch towards the wing tip) to illustration's in the books. IE most often you need it in your hand to do the ID.

Information Note:
In order to catch dragonflies or in fact any insect a permit from the provinces Nature Concervation is required

I please need some help in ID and explaining the dragonfly behavior I recently witnessed at Lake Panic.

As I was waiting for the Kingfisher action I noticed two different dragonflies behaving (according to my limited knowledge) very strangely. The blue was was flying around and as soon as it landed on a specific twig the red one would start pestering it, sometimes even landing on top of it. Is this a territorial behavior, different species or a mating ritual?? Comments and assistance will be appreciated.

While all this happened this purple dragonfly was relaxing in the sun…

I know much too little to make any expert comment on these guys.

I had a look through an identification guide. It is very difficult to identify the various species, but let me give it a try anyway.

The blue one is a male. Possibly a Navy Dropwing (But there are many other possibilities!)

The red one is also a male. Possibly a Little Scarlet.

I would suggest that they are probably competing for a nice vantage point. There should be no competition between the species for mating rights.

The third onlooker is a male Violet Dropwing.

Hi Imberbe, thank you for the feedback. On my trip report that I just started Pawps from Australia replied (and I checked Dr Google afterwards) that it looks like Two-striped Skimmers (Orthetrum caffrum) and he postulates that it is a male and female in a courting mood :redface:
