Walking Sticks!


The walking stick is one of the best experts in camouflage!  During this last week in Manuel Antonio National Park, we found a territory of several of these insects. The walking stick is an insect that is hard to find because the shape is like a little branch and does not move at all, so it blends very well.  It is also the same color as the plant.  The lifecycle of this insect is around one year. It is nocturnal and territorial.  Normally, the walking stick is not going to move more than 9 feet from its feed plant.
During the day it stays in the same place until the night arrives. When this insect starts to grow, first it is green, then light brown and eventually becoming darker brown. Costa Rica is a paradise for more than 200,000 species of insects, but the walking stick is one of the most successful, because thanks to its camouflage, it can avoid the predators and keep the next generations alive.
