Actias Maenas
The Malaysian moon moth (''Actias maenas'') is a Saturniid in the subfamily Saturniinae from Indomalaya. The male is purplish-brown and yellow, while the larger female is overall light green. Taxonomy The species is considered to form a superspecies complex that includes '' Actias ignescens'' Moore 1877 from the Andamans, ''Actias isis'' (Sonthonnax 1897) from Sulawesi, and ''Actias groenendaeli'' Roepke 1954 from Flores, Timor and Sumba. ''Actias rosenbergii'' (Kaup 1895) from Ambon is of doubtful status. This species is further divided into subspecies with the nominate from Continental Asia and ''A. m. diana'' Maassen 1872 from Sundas and in the Philippines. Range The Malaysian moon moth ranges from Malaysia, to Sumatra, Java, the Philippines, and the surrounding region in Southeast Asia. A population in the Western Ghats was described as a new species '' Actias keralensis'' in 2020. This species covers a diverse set of biomes, from tropical rainforests to evergreen f ...

Edward Doubleday
Edward Doubleday (9 October 1810 – 14 December 1849) was an English entomologist primarily interested in Lepidoptera. He is best known for ''The Genera of Diurnal Lepidoptera: Comprising Their Generic Characters, a Notice of Their Habits and Transformations, and a Catalogue of the Species of Each Genus'', co-written with John O. Westwood, and illustrated by William Chapman Hewitson; and ''List of the Specimens of Lepidopterous Insects in the Collection of the British Museum''. Doubleday was born on 9 October 1810 in Epping, Essex, the second son of Benjamin and Mary Doubleday. His older brother was Henry Doubleday (entomologist), Henry Doubleday who also grew up to become a notable entomologist. They were both interested in natural history and spent their childhood collecting specimens in the nearby Epping Forest. The boys grew up in a Quaker family and Edward received a good classical education at the local Quaker school. In 1835, he joined a fellow Quaker named Robert Foste ...

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

Actias
''Actias'' is a genus of Saturniid moths, which contains the Asian-American moon moths. Long tails on their hindwings are among their distinctive traits. Other moths with similar appearance are ''Copiopteryx'', '' Argema'' and '' Eudaemonia''. The majority of species in this genus feed on the leaves of sweetgum, pine, or similar trees. As with all Saturniids, adult ''Actias'' moths lack functional mouthparts so their lifespan after emergence from the cocoon only ranges from a few days to a week. Species The genus includes the following species: *'' Actias aliena'' (Butler, 1879) *'' Actias angulocaudata'' Naumann & Bouyer, 1998 *'' Actias apollo'' Röber, 1923 *'' Actias artemis'' ( Bremer & Gray, 1853) *'' Actias arianeae'' (Brechlin, 2007) *'' Actias australovietnama'' Brechlin, 2000 *'' Actias brevijuxta'' Nässig & Treadaway, 1997 *'' Actias callandra'' Jordan, 1911 – Andaman moon moth *'' Actias chapae'' Mell, 1950 *''Actias chrisbrechlinae'' (Brechlin, 2007) *''Act ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pupae
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Larvae
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...
