The newly hatched caterpillar stays in the middle of the upperside of the leaf. The first instar of the caterpillar is black, with a black head and two rows of subdorsal fleshy spines. The second, third, and fourth instars are dark, with a glossy, dark-brown head, and white markings on the eighth and ninth segments of the caterpillar, which resemble a white patch of uric acid deposited in a bird's droppings, helping them escape predation while remaining in moderately open places.
