Acripeza reticulata (Mountain Katydid, also known as Mountain Grasshopper) ~~~
The one on left and also the one on top-right is a female. When its wings are folded, it looks like a small lump of dirt and is not easy to be spotted. But when its wings are spread out, you can see the beautiful red, blue & black bands on its body.
The male is much skinnier - bottom-right.

Just looking at the photo, you wouldn't have imagined they are the same insect !
Above photo was taken in 2015 March, during a climbing trip to Gungartan Mountain in Kosciuszko National Park in NSW, Australia. Photos and trip report of that climb are in:
