Caterpillars are the larval stage of butterflies and moths, belonging to the order Lepidoptera. They are known for their distinct segmented bodies and voracious appetite. Caterpillars primarily feed on plant leaves, although some species are carnivorous. During their larval stage, caterpillars undergo multiple molts, shedding their exoskeletons as they grow. They often have vibrant colors or patterns, which can serve as a form of camouflage or warning to predators. After reaching a certain size, caterpillars enter the pupal stage and undergo metamorphosis, eventually emerging as adult butterflies or moths.
