While Chook-
and dog-sitting at Bellthorpe this week, I saw this amazing dragonfly. Nowhere
near water, it hung under a leaf on the path through the rainforest, and if it
hadn’t moved when Gretchen Evans and I walked past, I wouldn’t have noticed it,
as it blended so well into the background of sticks and leaves.
Others helped
with identification, as I couldn’t find a similar image on the websites I
usually consult. It is the Southern Giant Darner, Austrophlebia costalis, endemic to Australia. The wingspan was
about 14 cm, and the body about 12 cm long.
Al
Young says that the characteristics of this species are
- Its size – the largest in Queensland
- The eyes are in contact
- The
leading edge of the wing has dark red numerouscross veins
- U-shaped white markings on the thorax
- Plain coloured abdomen
Apparently this
species is not uncommon, and is usually seen
hunting along fresh water streams.
It is not
endangered in any way. I was stunned by its size, and
can only imagine with awe the huge
dragonflies
measuring up to 70 cm across which hunted along
streams during the Carboniferous
era, 300 million years ago.
