Giant Swallowtail - Papilio cresphontes

The Giant Swallowtail is sometimes a pest on citrus trees, hence the other common name of Orange Dog. The Giant Swallowtail caterpillars can make a mess of a small tree but rarely do significant damage to a full sized tree. The caterpillars feed on a variety of other plants from the Rutacea family. The Giant Swallowtail caterpillars are a bird poop mimic. And the butterflies are spectacular, welcome additions to most any butterfly garden. The adults sip nectar from a wide variety of plants including this Lantana, honeysuckle, verbena, a variety of plants in the carnation family and a bunch more in the daisy family, milkweeds, azaleas and bouganvillea. The Giant Swallowtail eggs look like bits of orange peel and age to black.
