A man's gotta eat. A man's gotta drink. A man's gotta climb mountains. And a man's gotta laugh.


1st woman : Where is your husband ?
2nd woman: We had an argument. He is in the garden.
1st woman : I was there and I didn't see him.
2nd woman: Dig deeper.

Birdwood Gully Round Walk
An arch in an interesting overhang.





Glow-worm and its sticky silk threads
Under ultra-violet & red lights combination, they show up nicely.





Prolog

Birdwood Gully Round Walk is a circuit walk.

The circuit takes us about 1.5 hours to complete.
Short and relaxed 😀

And if you don’t stop for photographs,
you can finish it within an hour.




This trip

We go once in the afternoon,
to familiarise ourselves with the track.
Then at night again, to check out the glow-worms.

I was here 3 months ago, 2024-March,
with John Graham and others.

As this place is close to Sydney,
easy for us to see glow-worms,
hence I am here again,
and taking a group along.




Our group

6 of us:
- Paul ... leading
- Elizabeth Zhu
- George He
- John Zhong
- Lydia Zhang
- Kelly Wei




Glow-worms, Arachnocampa richardsae

Glow-worms are insects having a bioluminescent larval stage.

The roof of a cave / overhang covered with glow-worms can look remarkably like a blue starry night sky ... due to the collective bioluminescent glow from the larvae.

The larva hangs down sticky silk threads from the ceiling of a cave.  The glow from its head attracts prey and ensnare them in the threads.

Generally glow-worms have few predators.
Their greatest danger is from human interference.

Perhaps we shouldn’t have come here at Birdwood Gully 😭

More detail on glow-worms is in Wikipedia:
