Well I have never set foot on Bali, but did work on Borneo for 11 years. The insect life in SE Asia is truly amazing. There are huge cicadas as big as your thumb, rhinoceros beetles that can fly, poisonous centipedes 10 inches long, several species of praying mantises and walking sticks.
However I have never seen anything resembling the creature in the photo. I hope the homeowner captured it so it can be studied.
