The Common Baron Caterpillar is a true master of camouflage. When it positions itself perfectly on a mango tree leaf, it is nearly impossible to spot, even if you know it’s there.
Some animals naturally develop camouflage in order to make themselves harder to spot by predators, but some are much better than others, and some blend into their natural surroundings perfectly. The Common Baron Caterpillar (Euthalia aconthea), a critter native to India and Southeast Asia, fits in the latter category. It has evolved to blend into its preferred background so well that it is nearly impossible to see.
