Twig-mimicking Katydid

During an evening walk, I came upon this awesome creature resting on a sandstone wall which obviously rendered its superb mimicry redundant at that moment! These katydids are nocturnally active, feeding on the nectar of flowering trees and shrubs.
I had to sacrifice some antennae length in the shot to keep detail. They were insanely long, over twice the length of the body. Approx' 4cm body length.
