Orange Dog

Orange Dog

The giant swallowtail (Papilio cresphontes) is the largest butterfly in North America. It is abundant through many parts of eastern North America; populations from western North America and down into Panama are now (as of 2014) considered to belong to a different species, Papilio rumiko. Though it is often valued in gardens for its striking appearance, its larval stage can be a serious pest to citrus farms, which has earned its caterpillars the names orange dog or orange puppy. The giant swallowtail caterpillars possess remarkable camouflage from predators by closely resembling bird droppings. They use this, along with their osmeteria, to defend against predators such as wasps, flies, and vertebrates.
