Check out Phobaeticus serratipes (formerly known as Pharnacia serratipes) . These walking sticks are denizens of Malaysia. And as you can see, they have earned their title. This particular specimen is a 17 inch female. They like to dine on bramble, oak, and Photinia. They are winged, though they can't fly.
That's got to be frustrating: being given useless wings. Such a cruel taunt.
BTW, check out the links below. There are some really cool photos and great info and supplies (and pets) for petkeepers.
