Adaptation

                  The species Diaoheromera femorata  has made made numerous adaptations that allow it to survive in its environment. They have developed a long slender branch looking body that is in either a green or brownish color in order to create a camouflage effect with the surrounding vegetation to avoid predators (Resh and Carde 2003). Also they have a tough outer exoskeleton made of chitin in order deter predators as well as serve as protection from the forest. The development of 2 antenna have aided in the ability to detect changes in environment including climate and chemical disturbances. These antennae also help in detecting predators. For movement they have 3 pairs of jointed legs which contain 2 claws and 4 suction pads on each leg. These claws and suction pads help aid in movement along steep and slick surfaces so they can obtain their food and escape their prey (O'Tool 2002).

Adaptation

·         Camouflage

   o   The Walking Stick is from the family Phasmidae, meaning ghost. As their common name suggests, camouflage is their most conspicuous (or inconspicuous) adaptation. Their morphology allows them to blend in with their prey/hosts in such a way that the insect virtually becomes a part of the plant (EOL 2005).

·         Feigning Death

   o   If threatened, the walking stick feigns death and falls from its tree of residence. The clever bug then lies motionless on the  ground; it becomes nearly invisible (Arment 2006).
