Dragonflies in Blue

diplacodes-trivialis-2-chalky-percher1 A couple of views of  Diplacodes trivialis (Chalky Percher)showing the different wing positions at rest.   This mature male had selected his territory and was cruising a short distance around the pond before resting in the same area of silt-covered sedge, so it gave me a reasonable chance of a photo.


Orthetrum caledonicum has been given the common name of Blue Skimmer in the ‘Complete Field Guide to Dragonflies of Australia’. Another male guarding his territory and waiting for the arrival of a female mate.   He was at the other end of the same small pond!

And one more photo in this series of blue Libellulidae – Allen took this shot of Brachydiplax denticauda (Palemouth) in March last year with our earlier model Lumix so the definition isn’t quite as good.  However, I want to include the photo to demonstrate the subtle differences of some our blue dragonflies.


I think my identification skills are slowly improving but please comment if you think there could be an error.

  1. Heads and eyes seem to be best place to look for differences. Inspecting more closely helps – as shown by seeing fly beneath the Palemouth!.

  2. Beautiful creatures! and great details on your photos.

  3. Hi Tony, Allen was pleased you noticed the fly!

    Thanks Mick – a decent photo really helps with the identification process.

    I think the picture of a male O. caledonicum shows a male Brachydiplax. The metallic frons (‘nose’) is not present in Orthetrum but is in Brachydiplax. I think it is a B. duivenbodi based on the lack of a black tip to the abdomen.

    • Thank you for sorting out my identification problem Vincent. My reference material is somewhat lacking on Brachydiplax duivenbodi ….
      I have now replaced the photo of Brachydiplax duivenboidei with what I hope is Orthetrum caledonicum (male).
