The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family. The family was created by William John Swainson in 1820.
Skippers are a group of butterflies placed in the family Hesperiidae within the order Lepidoptera. They were previously placed in a separate superfamily, Hesperioidea; however, the most recent taxonomy places the family in the superfamily Papilionoidea, the butterflies. They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. Moreover, skippers mostly have an absence of wing-coupling structure available in most moths. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.
Lycaenidae is the second-largest family of butterflies, with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species.
Pieris, the whites or garden whites, is a widespread now almost cosmopolitan genus of butterflies of the family Pieridae. The highest species diversity is in the Palearctic, with a higher diversity in Europe and eastern North America than the similar and closely related Pontia. The females of many Pieris butterflies are UV reflecting, while the male wings are strongly UV absorbing due to pigments in the scales.
Riodinidae is the family of metalmark butterflies. The common name "metalmarks" refers to the small, metallic-looking spots commonly found on their wings. The 1,532 species are placed in 146 genera. Although mostly Neotropical in distribution, the family is also represented both in the Nearctic, Palearctic, Australasian (Dicallaneura), Afrotropic, and Indomalayan realms.
The viceroy is a North American butterfly. It was long thought to be a Batesian mimic of the monarch butterfly, but since the viceroy is also distasteful to predators, it is now considered a Müllerian mimic instead.
The Pierinae are a large subfamily of pierid butterflies. The subfamily is one of several clades of butterflies often referred to as the whites.
The Parnassiinae or snow Apollos are a subfamily of the swallowtail butterfly family, Papilionidae. The subfamily includes about 50 medium-sized, white or yellow species. The snow Apollos are high-altitude butterflies and are distributed across Asia, Europe and North America.
Pyrginae, commonly known as spread-winged skippers, are a subfamily of the skipper butterfly family (Hesperiidae). The subfamily was established by Hermann Burmeister in 1878. Their delimitation and internal systematics has changed considerably in recent years with the most recent review being in 2019.
The Satyrinae, the satyrines or satyrids, commonly known as the browns, are a subfamily of the Nymphalidae. They were formerly considered a distinct family, Satyridae. This group contains nearly half of the known diversity of brush-footed butterflies. The true number of the Satyrinae species is estimated to exceed 2,400.
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.
Lorquin's admiral is a butterfly in the Nymphalinae subfamily. The butterfly is named after Pierre Joseph Michel Lorquin, a French naturalist who came to California from France during the Gold Rush, and made important discoveries on the natural history of the terrain.
The subfamily Theclinae is a group of butterflies, often referred to as hairstreaks, with some species instead known as elfins or by other names. The group is part of the family Lycaenidae, the "gossamer-winged butterflies". There are many tropical species as well as a number found in the Americas. Tropical hairstreaks often have iridescent blue coloration above, caused by reflected light from the structure of the wing scales rather than by pigment. Hairstreaks from North America are commonly brown above. Few Theclinae are migratory. Members of this group are described as 'thecline'.
Colias is a genus of butterflies in the family Pieridae. They are often called clouded yellows in the Palearctic and sulphurs in North America. The closest living relative is the genus Zerene, which is sometimes included in Colias.
Pontia is a genus of pierid butterflies. They are found in the Holarctic, but are rare in Europe and central to eastern North America, and a few species range into the Afrotropics. Several East Asian species once placed here are now more often split off in Sinopieris. Like the closely related genus Pieris, they are commonly called whites.
Riodininae is the largest of the three subfamilies within the metalmark butterfly family, Riodinidae.
Boloria is a brush-footed butterfly (Nymphalidae) genus. Clossiana is usually included with it nowadays, though some authors still consider it distinct and it seems to warrant recognition as a subgenus at least.
Speyeria, commonly known as greater fritillaries, is a genus of butterflies in the family Nymphalidae commonly found in North America, Europe, and Asia. Some authors used to consider this taxon a subgenus of Argynnis, but it has been reestablished as a separate genus in 2017.
Limenitis weidemeyerii, or Weidemeyer's admiral, is a butterfly from the subfamily Nymphalinae, found in western North America.
