The large blue is a species of butterfly in the family Lycaenidae. The species was first defined in 1758 and first recorded in Britain in 1795. In 1979 the species became mostly extinct in Britain but has been successfully reintroduced with new conservation methods. The species is classified as "near threatened" on the IUCN Red List of Threatened Species. Today P. arion can be found in Europe, the Caucasus, Armenia, western Siberia, Altai, north-western Kazakhstan and Sichuan.
Papilio polyxenes, the (eastern) black swallowtail, American swallowtail or parsnip swallowtail, is a butterfly found throughout much of North America. An extremely similar-appearing species, Papilio joanae, occurs in the Ozark Mountains region, but it appears to be closely related to Papilio machaon, rather than P. polyxenes. The species is named after the figure in Greek mythology, Polyxena, who was the youngest daughter of King Priam of Troy. Its caterpillar is called the parsley worm because the caterpillar feeds on parsley.
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.
The common blue butterfly or European common blue is a butterfly in the family Lycaenidae and subfamily Polyommatinae. The butterfly is found throughout the Palearctic and has been introduced to North America. Butterflies in the Polyommatinae are collectively called blues, from the coloring of the wings. Common blue males usually have wings that are blue above with a black-brown border and a white fringe. The females are usually brown above with a blue dusting and orange spots.
The Menelaus blue morpho is one of thirty species of butterfly in the subfamily Morphinae. Its wingspan is approximately 12 cm (4.7"), and its dorsal forewings and hindwings are a bright, iridescent blue edged with black, while the ventral surfaces are brown. Its iridescent wings are an area of interest in research because of their unique microstructure. Due to its characteristic blue color, Morpho menelaus is considered valuable among collectors and was widely hunted in the 20th century.
Junonia coenia, known as the common buckeye or buckeye, is a butterfly in the family Nymphalidae. Its range covers much of North America and some of Central America, including most of the eastern half of the US, the lower to middle Midwest, the Southwest, southern Canada, and Mexico. Its habitat is open areas with low vegetation and some bare ground. Its original ancestry has been traced to Africa, which then experiences divergence in Asia. The species Junonia grisea, the gray buckeye, is found west of the Rocky Mountains and was formerly a subspecies of Junonia coenia.
The Adonis blue is a butterfly in the family Lycaenidae. It inhabits the Palearctic realm.
Atrophaneura varuna, the common batwing, is a butterfly found in India and Southeast Asia that belongs to the swallowtail family, and more specifically, the batwings group of Atrophaneura, comprising tailless black swallowtail butterflies.
Fender's blue butterfly is a subspecies of Boisduval's blue endemic to the Willamette Valley of northwestern Oregon, United States. The potential range of the butterfly extends from south and west of Portland, OR to south of Eugene, OR. The butterfly is host-specific on the Kincaid's lupine, which it relies on for reproduction and growth. The male and female can be identified by their difference in wing color. The Fender's Blue Butterfly was added to the endangered species list in January 2000, but as of February of 2023, has been reclassified as "threatened". The Fender's blue butterfly population has increased over the past 20 years and projected to increase more through conservation efforts. In Willamette Valley, Oregon, there are currently 90 sites filled with Fender's blue.
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.
Horaga onyx, the common onyx, is a species of lycaenid or blue butterfly found in the Indomalayan realm.
The Oregon swallowtail is a subspecies of swallowtail butterfly native to the United States of America, Oregon, Washington, and Idaho and south-central British Columbia in Canada. In 1976, it became one of the first four butterflies that the United States Postal Service placed on a U.S. stamp.
Horaga is a genus of butterflies in the family Lycaenidae which John Nevill Eliot, 1973, places in the tribe Horagini of the subfamily Theclinae. The wings are blue, purple or brown above, with broad black costal and distal margins and usually a white discal spot on the forewing. The female is dingier than the male. The underside is ochreous, or ochreous brown, with a dark postdiscal line on both wings outwardly edged with white, this edging forming a broad white band not continued much above vein 6, on the forewing, but narrower and outwardly diffuse on the hindwing. The hindwing bears filamentous tails at veins 1b, 1 and 3 and, beneath. The pattern of H. araotina is aberrant.
Amathusiini is a tribe of the nymphalid butterfly subfamily Morphinae. They are large butterflies. They are sometimes treated as a distinct subfamily Amathusiinae or family Amathusiidae.
Zeuxidia aurelius, the giant Saturn, is a species of butterfly of the family Nymphalidae. It is found in Sumatra, Peninsular Malaysia and Borneo.
Zeuxidia masoni is a species of butterfly of the family Nymphalidae. It is found in Burma, the Mergui Archipelago and Thailand.
The blue copper, also known as Lycaena heteronea, is an American butterfly that belongs to the gossamer-winged family. The butterfly is named so because of the bright blue hue of the upper side of the males' wings. Females are brown on their upper side. Both sexes are white with black spots on the underside of the wings. Blue coppers are seen on the west coast of the United States and the southwest region of Canada, particularly British Columbia and Alberta. The males are often confused with Boisduval’s blue, another species of butterfly. Blue coppers prefer to live in areas where species of Eriogonum are found. Blue copper larvae sometimes form mutualistic associations with Formica francoeuri, an ant species.
Zeuxidia doubledayi , the Scarce Saturn, is a large butterfly that belongs to the Morphinae group of the family Nymphalidae. It was described by John Obadiah Westwood in 1851. It is found in the Indomalayan realm.
