The giant swallowtail (Papilio cresphontes) is a swallowtail butterfly common in various parts of North America and marginally into South America (Colombia and Venezuela only). In the United States and Canada it is mainly found in the south and east. With a wingspan of about 10–16 cm (3.9–6.3 in),[2] it is the largest butterfly in Canada and the United States.[3]

Description
Adult
An adult's wingspan is about 100–160 mm (3.9–6.3 in).[2] The body and wings are dark brown to black with yellow bands. There is a yellow "eye" in each wing tail. The abdomen has bands of yellow along with the previously mentioned brown. Adults are quite similar to the adults of another Papilio species, P. thoas.
Caterpillar
The mature caterpillar resembles bird droppings to deter predators, and if that doesn't work they use their orange osmeteria.These are 'horns' which they can display and then retract. The coloration is dingy brown and or olive with white patches and small patches of purple. Citrus fruit farmers often call the caterpillars orange dogs or orange puppies because of the devastation they can cause to their crops.
Range and habitat
In the United States, P. cresphontes is mostly seen in deciduous forest and citrus orchards where they are considered a major pest. They fly between May and August where there are 2 broods in the North and 3 in the south. They can range from southern California (where they have been seen from March to December, reaching peak abundance in late summer/early fall), Arizona as deep south as Mexico north into southeastern Canada. Outside USA and Canada they are found in Mexico, Central America, Colombia, Jamaica, and Cuba.
Life cycle
Adult females lay their eggs singly on the surface of the host plant, this egg is bright orange and darkens with time. The caterpillars then eat and grow to about 2 in (5.1 cm) before changing into a chrysalis. The chrysalis stage is variable but usually takes approximately 10–12 days, although in the fall they may stay in the chrysalis stage over winter and emerge in the spring.

Flight
Giant swallowtails fly from Late May–August, but in some areas of the southern United States such as Texas and Louisiana, they may be seen as late as October. All giant swallowtails have a distinctive flight pattern which generally looks as if they are "hopping" through the air. Females tend to beat their wings slowly but move quickly. Because females have such large wings, each wing beat will carry it a long way. Males however, tend to have more of a darty flight and beat their wings rapidly but move slower than females because their wings are smaller and each beat doesn't carry them far. Giant swallowtails in general fly fast and high and can be difficult to capture.
