But this dynastor darius darius is not what it seems.
This odd little critter has a distinctive appearance while it is in the pupal stage. It disguises itself as a fearful predator to protect its cocoon from predators.
The caterpillar goes through the amazing change into a butterfly while securely parading itself as a deadly killer.
While in the cocoon, the pupa is still aware of the world around it. When danger approaches, it shakes itself back and forth, giving the impression that this "pit viper" is very much alive and dangerous.
