Common Emigrant
''Catopsilia pomona'', the common emigrant or lemon emigrant, is a medium-sized pierid butterfly found in Asia and parts of Australia. The species gets its name from its habit of migration. Some early authors considered them as two distinct species ''Catopsilia crocale'' and ''Catopsilia pomona''. Description The species has pale and dark morphs in Australia. The form ''crocale'' has the antennae black and the form ''pomona'' has the antennae pinkish or red. The development of these forms has been linked to photoperiod and temperature during growth. Male Quoted from Bingham, C. T. (1907) ''The Fauna of British India, Including Ceylon and Burma: Butterflies'' volume 2. "The upperside of the male is chalky-white, sometimes with a more or less broad and clearly defined basal sulphur-yellow area on both fore and hind wings; this sulphur-yellow colour is at times diffused over the whole surface of the wings, though generally it becomes paler towards the terminal margins.

Johan Christian Fabricius
Johann Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johann Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks H ...

Butterflies Of Indochina
Butterflies are winged insects from the lepidopteran Superfamily (taxonomy), superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage Biological life cycle, life cycle, and like other Holometabola, holometabolous insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while othe ...

Coliadinae
Coliadinae, the sulphurs or yellows, are a subfamily of butterflies with about 300 described species. There are 36 species in North America, where they range from Mexico to northern Canada. In most species, males are easily distinguished from females. For example, in the genera ''Colias'' and ''Gonepteryx''), males exhibit brilliant UV reflections that the females lack. Systematics The Coliadinae can be arranged in the three traditional tribe (biology), tribes and a basal (evolution), basal lineage, with one genus of unclear placement. The taxa—including some selected species—are arranged here in the presumed phylogenetic sequence, from the most ancient lineages to the most modern ones:Brower (2006) Basal lineage * ''Kricogonia'' Reakirt, 1863 * ''Nathalis'' Boisduval, [1836] Euremini * ''Terias'' Swainson, 1821 * ''Pyrisitia'' Butler, 1870 * ''Abaeis'' Hübner, [1819] * ''Eurema'' Hübner, [1819] – grass yellows * ''Leucidia'' Doubleday, [1847] * ''Teriocolias' ...

List Of Butterflies Of India (Pieridae)
This is a list of the pierid butterflies of India. It forms part of the full List of butterflies of India. The family Pieridae, or the whites and yellows are a family of butterflies of moderate or small size. The common names refer to the two predominant colours found on the wings of these butterflies along with markings in black. Of the 1051 species of pierids occurring in the world, 81 species in 21 genera are found in India. Distinguishing features * Outline of wings usually regular. Hindwings are never tailed. * Forelegs are fully developed in both sexes. * The hindwings are channelled at the abdomen to fit the abdomen.

Instar
An instar (, from the Latin '' īnstar'' 'form, likeness') is a developmental stage of arthropods, such as insects, which occurs 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 ny ...

Thomas Reid Davys Bell
Thomas Reid Davys Bell (2 May 1863 – 24 June 1948) was a lepidopterist, naturalist and forest officer who worked in India. Bell collected natural history specimens, studied birds and the life histories of butterflies and moths in his spare time. His large collection of entomological specimens are held at the Natural History Museum, London. A number of species have been named from his collections, several commemorating him. Life and work Bell was born in Bandon, Cork. Thomas was the youngest in a family of twelve. His mother left Ireland and moved to Dresden where he received his early education.Rao, BR Subba (1998) History of Entomology in India. Institution of Agricultural Technologists, Bangalore.

Catopsilia Pyranthe
''Catopsilia pyranthe'', the mottled emigrant, is a medium-sized butterfly of the family Pieridae found in south Asia, southeast Asia, and parts of Australia. Description Male The upperside is chalky white, slightly tinted in some specimens with green. The forewing is with or without a discocellular black spot, that varies in size; costa and termen sometimes without a black margin; occasionally the costa has its apical third narrowly black, broadened slightly at the apex with black spots between the anterior veins; or again, the costa may be narrowly black, the apex very broadly so, and this colour continued down the termen but narrowed posteriorly. The hindwing is sometimes immaculate, but generally with narrow terminal black spots at the apices of the veins, these often reduced to mere dots, or again so broadened as to coalesce into a narrow terminal black margin. The underside's ground colour is similar, suffused on the anterior half of the forewing and over the whole surfac ...

Sesbania
''Sesbania'' is a genus of flowering plants in the pea family, Fabaceae, and the only genus found in tribe Sesbanieae. Riverhemp is a common name for plants in this genus. Notable species include the rattlebox (''Sesbania punicea''), spiny sesbania (''Sesbania bispinosa''), and ''Sesbania sesban'', which is used in cooking. Plants of this genus, some of which are Aquatic plant, aquatic, can be used in alley cropping to increase the soil's nitrogen content. The species of rhizobia responsible for nitrogen fixation in ''Sesbania rostrata'' is ''Azorhizobium caulinodans''. Some 60 species are currently accepted, with about 39 still unresolved. The genus is native to tropical and subtropical regions around the world, in the Americas from the southern United States to northern Argentina, in sub-Saharan Africa, in southern Asia, and in New Guinea, Australia, and the Pacific. The largest number of species are found in Africa, and the remainder in Australia, Hawaii, and Asia. Fossil rec ...
