A single common Baron caterpillar hatches from underneath a leaf, as this is the specialized area where a female Baron lays its egg. The common Baron caterpillar emerges equipped with small branches extending from its body that later grow and help it become a master of disguise. As it passes from leaf to branch in search of food in the mango and cashew trees, its plant-like texture lends itself perfect camouflage when it crawls over stems of broad, veined leaves.
