9pm Treetop Walk

I expected solitude but after walking about a hundred metres beside the fence and through the dark jungle path, I was surprised by the brightly lit Ranger Station manned by a Malay Ranger. A little guy was waiting for me at the toilet floor. I was on all fours looking at this critter, the Ranger checked momentarily but stopped at the entrance....
This is a big cricket (the arowana would choke on this one), wingless and 4-5cm long excluding the antennae which is only slightly shorter.
