Wildlife Spotting

This insect was about 10 cm long, and had 6 legs and 2 long antennae. It was brownish gray in colour, mottled like the bark of a tree, and had frills on its side and legs, possibly as bark camaflauge. The head is large, with 2 silver compound eyes. It's hard to see in the picture, but there were 2 sets of folded wings, appearing to be similar to transparent grasshopper wings, and there were two protrusions at the back of the abdomen.
