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.
Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings.
Pieris brassicae, the large white, also called cabbage butterfly, cabbage white, cabbage moth (erroneously), or in India the large cabbage white, is a butterfly in the family Pieridae. It is a close relative of the small white, Pieris rapae.
Anthocharis cardamines, the orange tip, is a butterfly in the family Pieridae, which contains about 1,100 species. A. cardamines is mainly found throughout Europe and temperate Asia (Palearctic) The males feature wings with a signature orange pigmentation, which is the origin of A. cardamines' common name.
Anthocharis midea, the falcate orangetip, is a North American butterfly that was described in 1809 by Jacob Hübner. It belongs to the family Pieridae, which is the white and sulphurs. These butterflies are mostly seen in the eastern United States, and in Texas and Oklahoma. They eat the nectar of violets and mustards. They tend to live in open, wet woods along waterways, in open swamps, and less often in dry woods and ridgetops. This species is a true springtime butterfly, being on the wing from April to May.
Anthocharis sara, the Sara Orangetip is one of three species in the Sara Orangetip complex. It is a California endemic butterfly with populations extending from Baja California into extreme southwest Oregon. The common name, Pacific Orangetip, is obsolete since its implied distribution includes two separate species.
Euchloe olympia, the Olympia marble, is a butterfly in the family Pieridae. Its range is southern Canada and the Midwest, down into the southwestern United States. E. olympia is related to E. guaymasensis, but has a distinctive phenotype and genotype.
Eurytides marcellus, the zebra swallowtail, is a swallowtail butterfly native to the eastern United States and south-eastern Canada. It is the state butterfly of Tennessee. Its distinctive wing shape and long tails make it easy to identify, and its black-and-white-striped pattern is reminiscent of a zebra. The butterflies are closely associated with pawpaws, and are rarely found far from these trees. The green or black caterpillars feed on the leaves of various pawpaw species, while the adults feed on flower nectar and minerals from damp soil.
The white-letter hairstreak is a butterfly in the family Lycaenidae.
The marsh fritillary is a butterfly of the family Nymphalidae. Commonly distributed in the Palearctic region, the marsh fritillary's common name derives from one of its several habitats, marshland. The prolonged larval stage lasts for approximately seven to eight months and includes a period of hibernation over the winter. The larvae are dependent on the host food plant Succisa pratensis not only for feeding but also for hibernation, because silken webs are formed on the host plant as the gregarious larvae enter hibernation. Females lay eggs in batches on the host plant and are, like other batch-layers, selective about the location of oviposition because offspring survivorship levels for batch-layers are more tied to location selection than they are for single-egg layers.
Euchloe ausonides insulanus, the island marble butterfly, is a subspecies of the Euchloe ausonides and is found in the San Juan Islands in Washington in the northwestern United States. The butterfly was thought to be extinct and was last observed on Gabriola Island, British Columbia in 1908. The species was rediscovered during a prairie butterfly survey in San Juan Island National Historical Park in 1998. After this rediscovery, surveys were conducted throughout the presumed range and found a few populations on San Juan Island and Lopez Island, but no remaining populations in Canada.
Euchloe ausonia, the eastern dappled white, is a southern European and Palearctic butterfly found mostly to the south and east of its almost indistinguishable relative the western dappled white.
The Mission blue is a blue or lycaenid butterfly subspecies native to the San Francisco Bay Area of the United States. The butterfly has been declared as endangered by the US federal government. It is a subspecies of Boisduval's blue.
The Appalachian azure is a butterfly in the gossamer wings family Lycaenidae. The male is light blue on the upperwing with a narrow, dark line running along the edge of the forewing. The underwing is chalky white and is dotted with small, pale dark spots. The very back of the hindwing has a row of dark spots running along the edge and contained by a faint zigzagging band. Females are similar to the males but have broad dark wing borders instead of the male's narrow ones. The adult butterfly has a 1.1–1.4-inch (2.8–3.6 cm) wingspan. It is the largest azure in the area.
Erynnis persius, commonly known as Persius duskywing, is a species of butterfly in the family Hesperiidae that occurs in North America. The eastern subspecies Erynnis persius persius is rarer and protected by law in some regions.
Edith's checkerspot is a species of butterfly in the family Nymphalidae. It is a resident species of western North America and among the subspecies, entomologists have long been intrigued by their many phenotypic variations in coloration, wing length, and overall body size. Most populations are monophagous and rely on plants including Plantago erecta and Orthocarpus densiflorus as their host species in developing from eggs through to larvae, pupae, and mature butterflies. Males exhibit polygyny whereas females rarely mate more than once. Males devote most of their attention to mate acquisition, and such mate locating strategies such as hilltopping behavior have developed. Climate change and habitat destruction have impacted certain subspecies. Three subspecies in particular, Euphydryas editha quino, Euphydryas editha bayensis and Euphydryas editha taylori, are currently under protection via the Endangered Species Act.
Papilio aristodemus, the Schaus' swallowtail or island swallowtail, is a species of American butterfly in the family Papilionidae. It is found in southern Florida in the United States and throughout the West Indies. It is named in honor of William Schaus.
Aphrissa statira, the statira sulphur, is a species of Lepidoptera in the family Pieridae. The species is a medium-sized yellow butterfly, with females more pale than males. They are found from southern regions of Florida and Texas through southern Brazil and northern Argentina. The caterpillars feed on the leaves of several local host plants, while adults prefer to feed on the nectar of red or orange colored flowers. The species is most noted for their dramatic migrations in the tropical areas of the Americas. They have been the subject of many studies about how butterflies navigate and orient during migration.
The crystal skipper is a species of butterfly in the family Hesperiidae that is found only along a 30-mile (50 km) stretch of barrier islands in North Carolina. The skipper was first discovered in 1978 and the paper describing it as a full species was published in 2015.
Ascia is a genus of butterflies in the family Pieridae. It is monotypic, being represented by the single species Ascia monuste, commonly known as the great southern white, In this species the sexes may differ with the female being either light or dark colored. It is found from the Atlantic and Gulf coasts of the United States, and south to Argentina. It is migratory along the south-eastern coast of the United States, with strays to Maryland, Kansas, and Colorado.
