Papilio glaucus, the eastern tiger swallowtail, is a species of butterfly native to eastern North America. It is one of the most familiar butterflies in the eastern United States, ranging north to southern Ontario, Canada, and is common in many different habitats. It flies from spring until fall, during which it produces two to three broods. Adults feed on the nectar of many species of flowers, mostly from those of the families Apocynaceae, Asteraceae, and Fabaceae. P. glaucus has a wingspan measuring 7.9 to 14 cm. The male is yellow with four black "tiger stripes" on each forewing. Females may be either yellow or black, making them dimorphic. The yellow morph is similar to the male, but with a conspicuous band of blue spots along the hindwing, while the dark morph is almost completely black.
Papilio is a genus in the swallowtail butterfly family, Papilionidae, as well as the only representative of the tribe Papilionini. The word papilio is Latin for butterfly.
Swallowtail butterflies are large, colorful butterflies in the family Papilionidae, and include over 550 species. Though the majority are tropical, members of the family inhabit every continent except Antarctica. The family includes the largest butterflies in the world, the birdwing butterflies of the genus Ornithoptera.
Salix discolor, the American pussy willow or glaucous willow, is a species of willow native to North America, one of two species commonly called pussy willow.
Papilio machaon, the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail. It is the type species of the genus Papilio. This widespread species is found in much of the Palearctic and in North America.
Limenitis arthemis, the red-spotted purple or white admiral, is a North American butterfly species in the cosmopolitan genus Limenitis. It has been studied for its evolution of mimicry, and for the several stable hybrid wing patterns within this nominal species; it is one of the most dramatic examples of hybridization between non-mimetic and mimetic populations.
Battus philenor, the pipevine swallowtail or blue swallowtail, is a swallowtail butterfly found in North America and Central America. This butterfly is black with iridescent-blue hindwings. They are found in many different habitats, but are most commonly found in forests. Caterpillars are often black or red, and feed on compatible plants of the genus Aristolochia. They are known for sequestering acids from the plants they feed on in order to defend themselves from predators by being poisonous when consumed. The adults feed on the nectar of a variety of flowers. Some species of Aristolochia are toxic to the larvae, typically tropical varieties. While enthusiasts have led citizen efforts to conserve pipevine swallowtails in their neighborhoods on the West coast, the butterfly has not been the subject of a formal program in conservation or protected in legislation. The butterfly is however of "Special Concern" in Michigan, which is on the Northern limit of its range.
Prunus emarginata, the bitter cherry or Oregon cherry, is a species of Prunus native to western North America, from British Columbia south to Baja California, and east as far as western Wyoming and New Mexico. It is often found in recently disturbed areas or open woods on nutrient-rich soil.
Papilio homerus, commonly known as the Homerus swallowtail or Jamaican swallowtail, is the largest butterfly species in the Western Hemisphere. The species is endangered and faces a potentially bleak future. Only two small populations of the Homerus swallowtail remain in a fraction of their original environment. It is endemic to Jamaica where the butterfly simultaneously serves as an icon of national pride and a need for conservation efforts. Over the past half century, the Jamaican swallowtail has been featured on various postal stamps and the Jamaican $1000 bill. In the face of rapid habitat destruction from human disruption and illegal collecting, the Jamaican swallowtail is listed on the Threatened Swallowtail Butterflies of the World by the International Union for Conservation of Nature and is protected under international and national level legislation.
Papilio appalachiensis, the Appalachian tiger swallowtail, is a species of swallowtail butterfly found in eastern North America, particularly in the Appalachian Mountains. It is a hybrid of another two Papilio species, Papilio canadensis and Papilio glaucus, with which it shares many characteristics. The butterflies are normally yellow and contain black patterns in their wings. Their wingspans range from 86 to 115 mm. The caterpillars range in color from green and yellow to orange and are ornamented with black specks that give them the appearance of a bird dropping, which is useful for camouflage, or a large eye, a form of mimicry that is also efficient for protection. This species is univoltine. Females lay their eggs in May.
