Papilio machaon caterpillar
A caterpillar from the species Papilio machaon, also known as the Old World Swallowtail. The caterpillar spends the first part of its life with the appearance of a bird dropping, which serves as an effective defense against predators. As the caterpillar grows larger, it becomes green with black and orange markings and becomes capable of releasing a foul smell if disturbed, which deters insects, but not birds.Photo: Archaeodontosaurus
