The giant swallowtail is a large swallowtail butterfly with a wingspan of up to 6 inches. This butterfly is an excellent example of countershading, being dark on the topsides of their wings and bright yellow on the bottom. This gives them better camouflage against predators. Giant swallowtails lay eggs on citrus trees, as well as prickly ash and common rue. Their caterpillars also display excellent camouflage, looking exactly like fresh bird droppings.
