Hippotion Velox
''Hippotion velox'', the dark striated hawkmoth, is a species of sphingid moth or the family Sphingidae. The species was described by Johan Christian Fabricius in 1793. Distribution It is found throughout the Indo-Australian tropics of India, Sri Lanka and east to Fiji and New Caledonia, north to Hong Kong, Taiwan, Sumatra southern Japan Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north ... and northern Australia from Western Australia to Queensland. Description The wingspan is 54–76 mm. The head and thorax are brown with pale lateral streaks. The abdomen is brown with numerous dark strigae and pairs of pale lateral striage on each segment. The forewings are brown without any silvery makings, thus differ from ''T. celerio''. Hindwings are smoky brown with traces of a da ...

Johan Christian Fabricius
Johan 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 Johan 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 Hospita ...

Eyespot (mimicry)
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species. They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; the best-known example is probably the eyespots on a peacock's display feathers. The pattern-forming biological process (morphogenesis) of eyespots in a wide variety of animals is controlled by a small number of genes active in embryonic development, including the genes called Engrailed, Distal-less, Hedgehog, Antennapedia, and the Notch signaling pathway. Artificial eyespots have been sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Morinda
''Morinda'' is a genus of flowering plants in the madder family, Rubiaceae. The generic name is derived from the Latin words ''morus'' "mulberry", from the appearance of the fruits, and ''indica'', meaning "of India". Description Distributed in all tropical regions of the world, ''Morinda'' includes 80 species of trees, shrubs or vines. All ''Morinda'' species bear aggregate or multiple fruits that can be fleshy (like ''Morinda citrifolia'') or dry. Most species of this genus originate in the area of Borneo, New Guinea, Northern Australia and New Caledonia. In traditional Japanese, Korean and Chinese medicine, ''Morinda citrifolia'' is considered to be a herb with biological properties, although there is no confirmed evidence of clinical efficacy. Fossil record The first fossil record for genus ''Morinda'' is from fruit of ''Morinda chinensis'' found in coal dated from the Eocene in the Changchang Basin of Hainan Island, South China.

Ipomoea
''Ipomoea'' () is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or water spinach, sweet potato, bindweed, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining climbing plants. Their most widespread common name is morning glory, but some species in related genera bear that same common name and some ''Ipomoea'' species are known by different common names. Those formerly separated in ''Calonyction'' (Greek "good" and , , , "night") are called moonflowers. The name ''Ipomoea'' is derived from the Greek , (, ), meaning "woodworm", and (), meaning "resembling". It refers to their twining habit. Uses and ecology Human uses of ''Ipomoea'' include: *Most species have spectacular, colorful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubiaceae
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include ''Coffea'', the source of coffee, '' Cinchona'', the source of the antimalarial alkaloid quinine, ornamental cultivars (''e.g.'', '' Gardenia'', ''Ixora'', ''Pentas''), and historically some dye plants (''e.g.'', ''Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, interpetiolar stipules, tubu ...

Nyctaginaceae
Nyctaginaceae, the four o'clock family, is a family of around 33 genera and 290 species of flowering plants, widely distributed in tropical and subtropical regions, with a few representatives in temperate regions. The family has a unique fruit type, called an " anthocarp", and many genera have extremely large (>100 µm) pollen grains. The family has been almost universally recognized by plant taxonomists. The APG II system (2003; unchanged from the APG system of 1998), assigns it to the order Caryophyllales in the clade core eudicots. A phylogenetic study by Levin has justified the combination of ''Selinocarpus'' and ''Ammocodon'' into the genus '' Acleisanthes''. The genus ''Izabalea'' is now considered a synonym of ''Agonandra'', a genus in Opiliaceae. A more recent study by Douglas and Manos clarified the relationships among almost all of the genera in the family and demonstrated that a substantial diversification of herbaceous genera has occurred in arid North America.

Convolvulaceae
Convolvulaceae (), commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato. Description Convolvulaceae can be recognized by their funnel-shaped, radially symmetrical corolla; the floral formula for the family has five sepals, five fused petals, five epipetalous stamens (stamens fused to the petals), and a two-part syncarpous and superior gynoecium. The stems of these plants are usually winding, hence their Latin name (from ''convolvere'', "to wind"). The leaves are simple and alternate, without stipules. In parasitic Cuscuta (dodder) they are reduced to scales. The fruit can be a capsule, berry, or nut, all containing only two seeds per one locule (one ovule/ovary). The leaves and starchy, tuberous roots of some species are used as foodstuffs (e.g. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araceae
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions. Many species display very decorative leaves and flowers, and they are widely used for gardening; popular as indoor plants and also outdoor plants where climates are mild, and winter freezes will not generally occur. However, some temperate species are also very popular in Mediterranean-climate gardening, or in moderately cool temperate zones, such as ''Zantedeschia''. Description Species within Araceae are often rhizomatous or tuberous, and the leaves nearly always contain calcium oxa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Somite
The somites (outdated term: primitive segments) are a set of bilaterally paired blocks of paraxial mesoderm that form in the embryonic stage of somitogenesis, along the head-to-tail axis in segmented animals. In vertebrates, somites subdivide into the dermatomes, myotomes, sclerotomes and syndetomes that give rise to the vertebrae of the vertebral column, rib cage, part of the occipital bone, skeletal muscle, cartilage, tendons, and skin (of the back). The word ''somite'' is sometimes also used in place of the word '' metamere''. In this definition, the somite is a homologously-paired structure in an animal body plan, such as is visible in annelids and arthropods. Development The mesoderm forms at the same time as the other two germ layers, the ectoderm and endoderm. The mesoderm at either side of the neural tube is called paraxial mesoderm. It is distinct from the mesoderm underneath the neural tube which is called the chordamesoderm that becomes the notochord. The pa ...

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 ...
