Chrysiridia
''Chrysiridia'' is a genus of uraniid moths from Africa including Madagascar. The genus was erected by Jacob Hübner in 1823. They are diurnal and strongly marked with iridescent colours. Species Listed alphabetically: *''Chrysiridia croesus'' (Gerstaecker, 1871) – African sunset moth, Croesus moth (East Africa) *''Chrysiridia rhipheus'' (Drury, 1773) – Madagascan sunset moth (Madagascar) An additional species, ''Chrysiridia prometheus'' (Drapiez, 1819), supposedly from the isolated South Atlantic island of Saint Helena Saint Helena () is a British overseas territory located in the South Atlantic Ocean.

Chrysiridia Rhipheus
''Chrysiridia rhipheus'', the Madagascan sunset moth, is a species of day-flying moth of the family Uraniidae. It is considered one of the most impressive and appealing-looking lepidopterans. Famous worldwide, it is featured in most coffee table books on Lepidoptera and is much sought after by collectors, though many older sources misspell the species name as "''ripheus''". The colours originate from optical interference in the iridescent parts of the wings, while the black parts are pigmented. Adults have a wingspan of . Dru Drury, who described the moth in 1773, placed it in the genus '' Papilio'', considering it a butterfly. Jacob Hübner placed it in the moth genus ''Chrysiridia'' in 1823. Later redescriptions led to junior synonyms such as ''Chrysiridia madagascariensis'' ( Lesson, 1831). At first the moth was thought to be from China or Bengal, but was later found to be endemic to Madagascar. It is found throughout the year in most parts of the island, with peak populatio ...

Uraniidae
The Uraniidae are a family of moths containing four subfamilies, 90 genera, and roughly 700 species. The family is distributed throughout the tropics of the Americas, Africa and Indo-Australia.Carter, David, ''Eyewitness Handbook to Butterflies and Moths'' (1992) pp. 190–191; Dorling Kindersley/New York, NY Some of the tropical species are known for their bright, butterfly-like colors and are called sunset moths (for example '' Chrysiridia rhipheus''). Such moths are apparently toxic and the bright colors are a warning to predators. The family Uraniidae contains both diurnal and nocturnal species. The day-flying species are usually more strikingly colored and vibrant than the nocturnal ones. Many diurnal species also have iridescent Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, feathers, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Hübner
Jacob Hübner (20 June 1761 – 13 September 1826, in Augsburg) was a German entomologist. He was the author of ''Sammlung Europäischer Schmetterlinge'' (1796–1805), a founding work of entomology. Scientific career Hübner was the author of ''Sammlung Europäischer Schmetterlinge'' (1796–1805), a founding work of entomology. He was one of the first specialists to work on the European Lepidoptera. He described many new species, for example ''Sesia bembeciformis'' and ''Euchloe tagis'', many of them common. He also described many new genera. He was a designer and engraver and from 1786 he worked for three years as a designer and engraver at a cotton factory in Ukraine. There he collected butterflies and moths including descriptions and illustrations of some in ''Beiträge zur Geschichte der Schmetterlinge'' (1786–1790) along with other new species from the countryside around his home in Augsburg. Hübner's masterwork "Tentamen" was intended as a discussion document. Inadver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Diurnality
Diurnality is a form of plant and animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which preferred pollinators ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Helena
Saint Helena () is a British overseas territory located in the South Atlantic Ocean. It is a remote volcanic tropical island west of the coast of south-western Africa, and east of Rio de Janeiro in South America. It is one of three constituent parts of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha. Saint Helena measures about and has a population of 4,439 per the 2021 census. It was named after Helena, mother of Constantine I. It is one of the most remote islands in the world and was uninhabited when discovered by the Portuguese enroute to the Indian subcontinent in 1502. For about four centuries the island was an important stopover for ships from Europe to Asia and back, while sailing around the African continent, until the opening of the Suez canal. St Helena is the United Kingdom's second-oldest overseas territory after Bermuda. Saint Helena is known for being the site of Napoleon's second exile, following his final defeat in ...
