Trychopeplus laciniatus is a stick insect commonly known as the moss mimic walking stick.
This species blends in to the moss that grows on trees in the dense rainforest that they live in. I think it is a pretty impressive camouflage. The intricate structures on the outside are just part of the insects exoskeleton which has grown into all kinds of weird and wonderful shapes.
Moss mimic walking sticks are found in Costa Rica.
