[edit] Larva

Giant Swallowtail caterpillars feed primarily on citrus plants, prickly ash, and hoptrees. They are known as Orange Dogs to citrus farmers because of their destructive capabilities.

The caterpillar has two effective adaptations for defense against birds. The first is a reddish osmeterium that is extended when the insect is provoked, releasing foul-smelling pheromones thought to deter birds. The larva are also camouflaged to resemble bird droppings.

[edit] Adult

The adults' wings are black, with two striking yellow stripes across the forewings and hindwings.

Giant Swallowtails feed on the nectar of a variety of flowers, but are known to enjoy azalea, bougainvilla, goldenrod, Japanese honeysuckle, and milkweed ^[2].
