Around 2007 I found this when I was walking along the Warburton Trail. The green part is exactly the size and shape and texture of a gum leaf.
I keep it in this box. I look at it occasionally. I wonder what insect it came from. I may never know. I guess maybe a grasshopper or something similar- a big one! Whatever the insect it is, I have never seen it.
It looks just like a fairy wing.
