William Chapman Hewitson was a British naturalist. A wealthy collector, Hewitson was particularly devoted to Coleoptera (beetles) and Lepidoptera and, also, to birds' nests and eggs. His collection of butterflies, collected by him as well as purchased from travellers throughout the world, was one of the largest and most important of his time. He contributed to and published many works on entomology and ornithology and was an accomplished scientific illustrator.
Celaenorrhinus is a genus of skipper butterflies which are commonly termed sprites. An alternate name is flats, for their habit of holding their wings flat when resting, but this is also used for related genera. They are the type genus of tribe Celaenorrhinini.
Arawacus is a genus of butterflies in the family Lycaenidae. They are commonly called stripestreaks. The species of this genus are found in the Neotropical realm.
Parides, commonly called cattlehearts, is a genus of swallowtail butterflies in the family Papilionidae. They are found in the Americas.
Pythonides is a genus of skippers.
Anthene is a genus of butterflies in the family Lycaenidae, commonly called the ciliate blues or hairtails. The genus was erected by Edward Doubleday in 1847.
Eunica is a genus of nymphalid butterflies found in the Neotropical realm.
Callicore is a genus of nymphalid butterfly found in the Neotropical realm. This genus, like some related ones, was formerly lumped together as the paraphyletic Catagramma assemblage.
Diaethria is a brush-footed butterfly genus found in the Neotropical realm, ranging from Mexico to Paraguay.
Pseudacraea is an Afrotropical butterfly genus in the subfamily Limenitidinae. Their placement in the tribe Limenitidini remains to be verified.
Oenomaus is a genus of butterflies in the family Lycaenidae. The species of this genus are found in the Neotropical realm.
Dalla is a genus of skippers in the family Hesperiidae.
Pronophilina is a Neotropical subtribe of butterflies of the subfamily Satyrinae. They are a species-rich group with highest diversity in the tropical and subtropical mountains, especially the Andes. Before 1970, they were poorly studied, but recent interest has resulted in high rates of species description from previously unexplored mountain ranges. However, there is still a lack of knowledge on their biology and ecology. Their relationship to other groups of Satyrine butterflies and their complex patterns of speciation within and among mountain ranges have led to several biogeographic discussions.
Dynamine postverta, the Mylitta greenwing or four-spot sailor, is a butterfly in the family Nymphalidae. It is found throughout most tropical and subtropical areas of Central and South America, from Mexico south to Argentina and Paraguay. The habitat includes primary rainforests, humid deciduous woodlands, scrubby grassland and farmland at altitudes up to about 900 metres.
Dalla calaon, the calaon skipperling, is a species of butterfly in the family Hesperiidae. It was first described in 1877 by William Chapman Hewitson, and is found in Ecuador.
Hermathena is a genus of butterflies in the family Riodinidae containing a total of three known species. A small Neotropical genus of uncommon montane butterflies. The larvae feed on bromeliads.
Ocaria ocrisia, the black hairstreak or Hewitson's blackstreak, is a butterfly of the family Lycaenidae. It was described by William Chapman Hewitson in 1868. It is found from Mexico to Brazil, Paraguay, Peru, Ecuador and Argentina. It has also been recorded in southern Arizona. The habitat consists of rainforests at altitudes ranging from 200 to 900 meters.
Euselasia is a genus of butterflies in the family Riodinidae. They are present only in the Neotropical realm. The genus was erected by Jacob Hübner in 1819.
Pseudoscada erruca is a South-American species of brush-footed butterfly in the Godyridina subtribe of Ithomiini. It was described in 1855 by William Chapman Hewitson as Ithomia erruca.
