Giant Swallowtail
Papilio cresphontes
The Giant Swallowtail is Florida’s largest butterfly, with bold yellow bands across dark wings and caterpillars that resemble bird droppings.
Giant Swallowtails occur throughout Florida wherever citrus-family host plants and nectar flowers are available. They visit both natural habitats and residential gardens.
Their caterpillars, called orange dogs, may eat citrus leaves. Established trees generally tolerate limited feeding, while young trees may need monitoring.
Habitat:
Pine Flatwoods and Sandhills, Forests and Woodlands, Grasslands and Agricultural Areas, Urban and Residential Areas
Area / Range:
Statewide
Diet:
Adults drink nectar from flowers. Caterpillars feed on citrus-family plants, including wild lime, Hercules’ club, and cultivated citrus.
Behavior:
Adults fly strongly through woodland edges and gardens. Females place single eggs on host leaves, and caterpillars rest exposed while relying on camouflage.
Day
Active Times:
Best time to see:
During warm daylight hours around flowering gardens, citrus trees, woodland edges, and native wild lime.
Florida Native Status:
Native
Conservation Status:
Widespread native butterfly. Pesticide exposure and loss of host and nectar plants reduce local habitat quality.
Safety Level:
Harmless
Safety Information:
The butterfly and caterpillar are harmless. Avoid handling and use hand-picking or targeted protection on small citrus rather than broad insecticide spraying.
Benefits to Property:
Adults pollinate flowers and add visible native wildlife value to Florida-friendly landscapes.
Property Concerns:
Caterpillars chew citrus foliage and may affect very young trees, though mature healthy citrus usually tolerates modest feeding.
Fun Fact:
The caterpillar resembles a bird dropping and can extend a forked, foul-smelling defensive organ called an osmeterium.
Wildlife Laws:
Avoid collecting wildlife in parks or preserves without permission. Follow site rules and protect native butterflies, host plants, and pollinator habitat.
Identification:
Adults have dark brown to black wings crossed by broad yellow bands, yellow spots, and long hindwing tails. The underside is mostly yellow with dark markings.
