Thasus Carchinus
''Thasus carchinus'' is a species of leaf-footed bug in South America. Description Female The head, first four segments of the antennae, upper body (pronotum and scutellum), and upper side of the abdomen are mostly black. However, some areas are yellow or reddish-orange, including the space between the eye and a small simple eye (ocellus), the outer edges of the pronotum (especially the spiny part), a tiny dot in the middle of the pronotum's back edge, and the tip of the scutellum. The hardened front wings (clavus and corium) range from reddish-brown to black, with pale yellow markings along the veins, edges, and scattered spots. The membranous part of the wings is dark brown with a metallic blue-violet sheen, and its veins and base are darker. The sides of the abdomen (connexivum) have alternating black and yellow segments, with the spines on segments 2-9 being yellow. The underside of the body is mostly black, but some areas—like parts of the head, a section of the middl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coreidae
Coreidae is a large family (biology), family of predominantly sap-sucking insects in the Hemipteran suborder Heteroptera. The name "Coreidae" derives from the genus ''Coreus'', which derives from the Ancient Greek () meaning bedbug. As a family, the Coreidae are Cosmopolitan distribution, cosmopolitan, but most of the species are tropical or subtropical. Common names and significance The common names of the Coreidae vary regionally. Leaf-footed bug refers to leaf-like expansions on the Insect morphology#Legs, legs of some species, generally on the hind tibiae. In North America, the pest status of species such as ''Anasa tristis'' on squash (plant), squash plants and other Cucurbitaceae, cucurbits gave rise to the name squash bugs. The Coreidae are called twig-wilters or tip-wilters in parts of Africa and Australia because many species feed on young twigs, injecting enzymes that wikt:macerate, macerate the tissues of the growing tips and cause them to wilt abruptly.

Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also * Glossary of entom ...

Scutellum (insect Anatomy)
The scutellum is the posterior portion of either the mesonotum or the metanotum of an insect Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, ... thorax; however, it is used almost exclusively in the former context, as the metanotum is rather reduced in most insect groups. In the Hemiptera, and some Coleoptera, the scutellum is a small triangular plate behind the pronotum and between the forewing bases. In Diptera and Hymenoptera, the scutellum is nearly always distinct, but much smaller than (and immediately posterior to) the mesoscutum.

Ocellus
A simple eye or ocellus (sometimes called a pigment pit) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish them from " compound eyes", which have multiple lenses. They are not necessarily simple in the sense of being uncomplicated or basic. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of most large animals are '' camera eyes'' and are sometimes considered "simple" because a sing ...

Corium (entomology)
The corium is the thickened, leathery, basal portion of the forewing or hemelytron of an insect in the order Hemiptera, suborder Heteroptera. Specifically, the large anterior portion of the basal region is the corium. Hemelytra The forewings of winged heteropterans are modified into hemelytra (singular, hemelytron), in which the basal part is thickened and leathery and the apical part is membranous. The thickened region is divided into a large, anterior corium and much smaller, posterior clavus. However, entomologists commonly refer to the whole basal region of the wing as the corium. The membranous apical region typically has veins and the venation is of taxonomic importance. However, in some families, the distinction between the leathery and membranous regions of the hemelytra is not pronounced, and the wings tend to be more fully sclerotized (e.g., Pleidae) or more fully membranous (e.g., winged Gerridae The Gerridae are a family of insects in the order Hemiptera, co ...

Mesopleuron
The mesothorax is the middle of the three segments of the thorax of hexapods, and bears the second pair of legs. Its principal sclerites (exoskeletal plates) are the mesonotum (dorsal), the mesosternum (ventral), and the mesopleuron (lateral) on each side. The mesothorax is the segment that bears the forewings in all winged insects, though sometimes these may be reduced or modified, as in beetles (Coleoptera) or Dermaptera, in which they are sclerotized to form the elytra ("wing covers"), and the Strepsiptera, in which they are reduced to form halteres that attach to the mesonotum. All adult insects possess legs on the mesothorax. In some groups of insects, the mesonotum is hypertrophied, such as in Diptera, Hymenoptera, and Lepidoptera), in which the anterior portion of the mesonotum (called the mesoscutum, or simply "scutum") forms most of the dorsal surface of the thorax. In these orders, there is also typically a small sclerite attached to the mesonotum that covers the wing b ... [...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 (anatomy), hip, : ''coxae''), ''trochanter'', ''femur'' (: ''femora''), ''tibia'' (: ''tibiae''), ''tarsus'' (: ''tarsi''), ''ischium'' (: ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (: ''patellae''). Homology (biology), 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 Neontology, 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 Homeobox, ''Hox''-gene, could result in Parallel evolution, parallel gains of leg segments ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...
