Survival of the fittest has been the norm in nature. Every organism that has to survive, has to find ways to escape from its predators or develop skills to adapt to the adversities of its environment.

A new study has now explored strategies used by the pupa during its developmental stages to hide from the prying eyes of the predators. It says that based on environmental factors, the pupal colors change, which might help them survive by camouflage.
