Eka (beetle)
''Eka nigra'' is a species of leaf beetle endemic to Silhouette Island in the Seychelles, in the low country near the coast, and the only member of the genus ''Eka''. The species was first described by the Indian entomologist Samarendra Maulik, from a specimen collected by the Percy Sladen Trust Expedition to the Indian Ocean in 1908. The generic name comes from the Sanskrit word (''éka''), meaning "single", "alone". The genus is related to ''Trichochrysea''. Description The body is oblong-ovate and colored black, with a very faint purplish tinge. The four segments at the base of the antennae are coloured brown, and the remaining seven segments are coloured black. The legs are brown mixed with blackish colour, the tarsi more blackish. The beetles are entirely covered in white erect hairs Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samarendra Maulik
Samarendra Nath Maulik (25 December 1881 in Tamluk – 9 July 1950 in Chelsea) was an Indian entomologist who worked at the Natural History Museum, London and specialized in the systematics of the leaf beetles. He worked briefly at the University of Calcutta as a professor of Zoology. A structure on the hind femur, particularly of flea beetles, and used in their leaping motion has sometimes been called as "Maulik's organ". Life and work Maulik was born in Tamluk, West Bengal. He studied physics, chemistry and mathematics at St Xavier's College, Calcutta but later became interested in biology from 1902 and started working in Assam, experimenting on the breeding of insects, particularly those feeding on tea plants. He then spent some time at the Forest Research Institute in Dehra Dun and at the Indian Museum under Nelson Annandale. He then went to live in Cambridge to study biology and then joined Imperial College to study entomology. After this he worked at the British Mus ...

Trichochrysea
''Trichochrysea'' is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Asia. According to A. G. Moseyko (in 2012), the Central Asian species are significantly different from the Oriental species. Species The genus includes the following species: South, East and Southeast Asian species: * '' Trichochrysea aeneipennis'' ( Lefèvre, 1890) * '' Trichochrysea albopilosa'' Medvedev & Eroshkina, 1987 * '' Trichochrysea annamita'' ( Lefèvre, 1877) * '' Trichochrysea antennata'' Jacoby, 1908 * '' Trichochrysea bhamoensis'' ( Jacoby, 1892) * '' Trichochrysea bidens'' ( Lefèvre, 1893) * '' Trichochrysea borneensis'' ( Jacoby, 1895) * '' Trichochrysea brevipennis'' Pic, 1926 * '' Trichochrysea cephalotes'' ( Lefèvre, 1893) * '' Trichochrysea chejudoana'' Komiya, 1985 * '' Trichochrysea chihtuana'' Komiya, 1985 * '' Trichochrysea clypeata'' ( Jacoby, 1889) * '' Trichochrysea cupreata'' ( Baly, 1867) * '' Trichochrysea curta'' Pic, 1926 * '' Trichochrysea ev ...

Insects Of Seychelles
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 eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetles Of Africa
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eumolpinae
The Eumolpinae are a subfamily of the leaf beetles, or Chrysomelidae. It is one of the largest subfamilies of leaf beetles, including more than 500 genera and 7000 species. They are oval, and convex in form, and measure up to 10 mm in size. Typical coloration for this subfamily of beetles ranges from bright yellow to dark red. Many species are iridescent or brilliantly metallic blue or green in appearance. Description Eumolpinae can be recognized at first sight by their rounded thoraces, more or less spherical or bell-shaped, but always significantly narrower than the mesothorax as covered by the elytra. Additional features include a small head set deeply into the thorax, and usually well-developed legs. They generally resemble other Chrysomelidae, but differ in having front coxae rounded and third tarsal segment bilobed beneath. Many are metallic, or yellow and spotted. The dogbane beetle (''Chrysochus auratus''), for instance, is very attractive—iridescent blue-green wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elytron
An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphoridae), o ...

Seta
In biology, setae (singular seta ; from the Latin word for "bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allows th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod Leg
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...
