This page contains information and pictures about Unicorn Darner Dragonflies that we found in the Brisbane area, Queensland, Australia.
- Female body length 50mm
- This Unicorn Darner
dragonfly is brightly blue in colour with black patterns on its thorax and
abdomen. Its eyes are also in blue colour.
- This dragonfly seems never rest, spend most of the time flying during the
day. We are very lucky to have taken the above set of pictures when it perch on a
leaf in the middle of the day, this is rarely happen for a Darner Dragonfly. Those pictures are taken near a pond along the Bulimba Creek in Wishart.
- Male, body length 75mm
- The male Unicorn Darner is even larger. The dragonfly is dark brown in colour with
greenish-yellow patterns. Notice its the angular hind wings base and the shape
of its superior appendage (tail), tell that the dragonfly is a male.
- We saw the male Unicorn Darner at rest only two times. The first time was
during mid-summer day in the Yugarapul Park forest. The second time was
in a semi-forest in Alexandra Hill. Every time it was heavily raining. We believed it was the heavy rain made the
dragonfly rested on grass under thick tree covers. Usually, a Darner dragonfly
will be flying or hovering during the day and hardly be seen resting.
- The dragonfly, as most other Darners, rested with body in vertical
position. After we took a few pictures, the dragonfly did not tolerance our approaching
and flied away slowly.
- We had wrongly identified the male Unicorn Darner as Austroaeschna pulchra, the
Beautiful Forest Darner. Our visitor in Sydney sent us emails advised that
this should be a male Unicorn Darner Austroaeschna unicornis. In here we
would like to thank our Sydney visitor again (he preferred not mention his
- When we first took this male dragonfly pictures, we identified this
dragonfly using the reference book "The Australian Dragonflies, Watson
and Theischinger", we had suspected this green dragonfly could be an A.
unicornis. But we had identified the female A. unicornis and they
look quite different.
- Our Sydney visitor advised that "In regard to the differences in colour : As in most
Austroaeschna species the colour of the pale
markings on synthorax and abdomen vary from almost white to cream over blue and green to finally
yellow depending on age and maybe other factors as well. Females are
invariably shorter/stouter than males and usually also less colourful."
