Luciola Cruciata
''Nipponoluciola cruciata'', known as "genji-botaru" (ゲンジボタル) in Japanese, is a species of firefly found in Japan. Its habitat is small ditches and streams, and its larvae are aquatic. It was formerly known as ''Luciola cruciata'' but was revised taxonomically in 2022. Taxonomy This species was described by Victor Motschulsky in 1854. The type locality is Japan, but it was incorrectly given as Java. Its Japanese name, "genji-botaru", may derive from '' The Tale of Genji'', an 11th-century Japanese novel, or it may derive from the Genji clan, which won the 12th-century Genpei War. (Another, smaller firefly species, '' Aquatica lateralis'', has the Japanese common name "heike-botaru", a possible reference to the Heike clan, the losers in the Genpei War). Description The male is long and wide. The female is larger, long and wide. The pronotum is reddish pink, with a central marking. The black elytra are elongate. In the male, the venter is brown and pale yellow, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victor Motschulsky
Victor Ivanovich Motschulsky (sometimes Victor von Motschulsky, russian: link=no, Виктор Иванович Мочульский, 11 April 1810, in St. Petersburg – 5 June 1871, in Simferopol) was a Russian entomologist mainly interested in beetles. Motschulsky was an Imperial Army colonel who undertook extended trips abroad. He studied and described many new beetles from Siberia, Alaska, the United States, Europe, and Asia. While he tended to ignore previous work and his own work on classification was of poor quality, Motschulsky made a massive contribution to entomology, exploring hitherto unworked regions, often in very difficult terrain. He described many new genera and species, a high proportion of which remain valid. Travels Motschulsky's travels included: *1836 - France, Switzerland and the Alps, northern Italy and Austria *1839–1840 - Russian Caucasus, Astrakhan, Kazan and Siberia *1847 - Khirgizia *1850–1851 - Germany, Austria, Egypt, India, France, England, ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Insects Of Japan
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioluminescent Insects
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and sometime ...

Lampyridae
The Lampyridae are a family (biology), family of Elateroidea, elateroid beetles with more than 2,000 described species, many of which are bioluminescence, light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly crepuscular, during twilight, to attract mates. Light production in the Lampyridae is thought to have originated as an honest signal, honest Aposematism, warning signal that the larvae were distasteful; this was co-opted in evolution as a mating signal in the adults. In a further development, female fireflies of the genus ''Photuris'' mimic the flash pattern of ''Photinus (beetle), Photinus'' species to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. While all known fireflies glow as larvae, only some species produce light in their adult stage, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Semisulcospira Libertina
''Semisulcospira libertina'' is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Semisulcospiridae. Widespread in east Asia, it lives in China, Taiwan, Korea, Japan, and the Philippines. In some countries it is harvested as a food source. It is medically important as a vector of clonorchiasis, paragonimiasis, metagonimiasis and others. Taxonomy The type specimens were collected by American scientist William Stimpson during the North Pacific Exploring and Surveying Expedition (1853–1856). This species was originally described under the name ''Melania libertina'' by American malacologist Augustus Addison Gould in 1859. The specific name ''libertina'' is from Latin language and means a "freedwoman". ''Semisulcospira libertina'' is the type species of the genus ''Semisulcospira'' by subsequent designation The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scient ...

Luciola Cruciata ゲンジボタル - Panoramio (1)
''Luciola'' is a genus of "flashing" fireflies (family Lampyridae), especially well known from Japan. They are often called "Japanese fireflies", but their members range farther into Asia and reach southern Europe (Italy, France, Spain, Portugal, among other countries) and Africa. This genus is traditionally held to extend to Australia, but these species do not seem to belong herein (see below for details). Biological description Unlike some other fireflies, the females of ''Luciola'' are fully winged. Ecologically, the genus is remarkable in that the larvae of several species are aquatic. The adults of the typical ''Luciola'' are similar to those of ''Atyphella'' which was formerly included in this genus. They can be easily distinguished by the males' aedeagus however, which in ''Luciola'' proper has large lateral lobes that do not taper and have elongated, slender and flattened smaller lobes along their ventral margin. The middle lobe of the males' aedeagus is very slim and ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okinawa
is a prefecture of Japan. Okinawa Prefecture is the southernmost and westernmost prefecture of Japan, has a population of 1,457,162 (as of 2 February 2020) and a geographic area of 2,281 km2 (880 sq mi). Naha is the capital and largest city of Okinawa Prefecture, with other major cities including Okinawa, Uruma, and Urasoe. Okinawa Prefecture encompasses two thirds of the Ryukyu Islands, including the Okinawa, Daitō and Sakishima groups, extending southwest from the Satsunan Islands of Kagoshima Prefecture to Taiwan ( Hualien and Yilan Counties). Okinawa Prefecture's largest island, Okinawa Island, is the home to a majority of Okinawa's population. Okinawa Prefecture's indigenous ethnic group are the Ryukyuan people, who also live in the Amami Islands of Kagoshima Prefecture. Okinawa Prefecture was ruled by the Ryukyu Kingdom from 1429 and unofficially annexed by Japan after the Invasion of Ryukyu in 1609. Okinawa Prefecture was officially founded in 1879 by the Empi ...

Hokkaido
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people. While geographers such as Mogami Tokunai and Mamiya Rinzō explored the isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ventrite
The sternum (pl. "sterna") is the ventral portion of a segment of an arthropod thorax or abdomen. In insects, the sterna are usually single, large sclerites, and external. However, they can sometimes be divided in two or more, in which case the subunits are called sternites, and may also be modified on the terminal abdominal segments so as to form part of the functional genitalia, in which case they are frequently reduced in size and development, and may become internalized and/or membranous. For a detailed explanation of the terminology, see Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods.Sørensen, M. V. et al. Phylogeny of Kinorhyncha based on morphology and two molecular loci. PLoS One 10, 1–33 (2015). Ventrites are externally visible sternites. Usually the first sternite is covered up, so that vertrite numbers do not correspond to sternid numbers. The term is also used in other arthropod groups such as crustaceans ...
