Korynetes Caeruleus
''Korynetes caeruleus'', also known as the steely blue beetle, is a predatory beetle in the family Cleridae. The species name is occasionally misspelled as "''coeruleus''" (e.g.,), but the spelling ''caeruleus'' is preserved by Opinion 604 of the ICZN, issued in 1961. The adult is between long, has reddish-brown antennae, a scantily spotted brown head and neck shield, and shiny blue elytra. The larvae live in tunnelled wood that has been infested by the common furniture beetle and the deathwatch beetle and they feed on the larvae of these wood-damaging insects. The presence of ''Korynetes caeruleus'' indicates a heavy infestation of either woodboring insect. Adult females mate and lay eggs near or just inside exit holes, then die. It is not to be confused with '' Necrobia rufipes'', which is also a steely blue beetle in the family Cleridae. Both beetles have a significance in forensic entomology Forensic entomology is a branch of applied entomology that uses insects and ot ...

Charles De Geer
Charles De Geer (30 January 1720 – 7 March 1778) was an entomology, entomologist, industrialist, civil servant and book collecting, book collector. He is sometimes referred to as Charles the Entomologist, to distinguish him from other relatives with the same name. Charles De Geer came from a prominent Swedish-Dutch family. Born in Sweden, he spent most of his childhood and youth in the Dutch Republic. At the age of 18 he moved back to Sweden and would spend the rest of his life there. Upon his return to Sweden, he took over the management of the ironworks of Lövstabruk. He was a successful businessman and with time became one of the richest men in Sweden, head of an early industry employing around 3,000 people. He had a successful civic career, became Marshal of the Court (Sweden), Marshal of the Court and was elevated to the rank of ''Freiherr#Swedish_and_Danish–Norwegian_title, friherre'' (baron) in 1773. De Geer had developed an interest in natural history and particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleridae
Cleridae are a family of beetles of the superfamily Cleroidea. They are commonly known as checkered beetles. The family Cleridae has a worldwide distribution, and a variety of habitats and feeding preferences. Cleridae have many Ecological niche, niches and feeding habits. Most genera are predaceous and feed on other beetles and larvae; however other genera are scavengers or pollen feeders. Clerids have elongated bodies with bristly hairs, are usually bright colored, and have variable Antenna (biology), antennae. Checkered beetles range in length between . Cleridae can be identified based on their 5–5–5 tarsal formula, division of sternites, and the absence of a special type of vesicle. Female Cleridae lay between 28–42 egg (biology), eggs at a time predominately under the Bark (botany), bark of trees. Larvae are predaceous and feed vigorously before pupation and subsequently emergence as adults. Clerids have a minor significance in forensic entomology. Some species are oc ...

ICZN
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * How to determine whether a given name is available * Which available name must be used in case of name conflicts ( valid name) * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus '' Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all anima ...

Elytron
An elytron (; ; : elytra, ) 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 Ripiphorid ...

Common Furniture Beetle
The common furniture beetle or common house borer (''Anobium punctatum'') is a woodboring beetle originally from Europe but now distributed worldwide. In the larval stage it bores in wood and feeds upon it. Adult ''Anobium punctatum'' measure in length. They have brown ellipsoidal bodies with a prothorax resembling a monk's cowl. The common furniture beetle is often confused with the drugstore beetle and cigarette beetle due to their similar appearance. The common furniture beetle can be distinguished from these other species by their lack of antennae as well as darker prothorax. Life cycle The female lays her eggs in cracks in wood or inside old exit holes, if available. The eggs hatch after some three weeks, each producing a long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to . They come nearer to the wood surface when ready to pupate. They excavat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deathwatch Beetle
The deathwatch beetle (''Xestobium rufovillosum'') is a species of woodboring beetle that sometimes infests the structural timbers of old buildings. The adult beetle is brown and measures on average long. Eggs are laid in dark crevices in old wood inside buildings, trees, and inside tunnels left behind by previous larvae. The larvae bore into the timber, feeding for up to ten years before pupating, and later emerging from the wood as adult beetles. Timber that has been damp and is affected by fungal decay is soft enough for the larvae to chew through. They obtain nourishment by using enzymes present in their gut to digest the cellulose and hemicellulose in the wood. The larvae of deathwatch beetles weaken the structural timbers of a building by tunneling through them. Treatment with insecticides to kill the larvae is largely ineffective, and killing the adult beetles when they emerge in spring and early summer may be a better option. However, infestation by these beetles is oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Necrobia Rufipes
''Necrobia rufipes'', the red-legged ham beetle, is a species of predatory beetle, in the family Cleridae, with a cosmopolitan distribution, first described by Charles De Geer in 1775. The adult beetles are long, convex, straight sided, and the surface has indentations called punctures. They are shiny metallic green or greenish blue. The legs and antennae are red (dark clubs). They feed on the meat-infesting larvae of ''Calliphora'' or blow flies, Dermestidae and Piophilidae. The adults are surface feeders; the larvae bore into dry or smoked meats and do most damage. The red-legged ham beetle also attacks bones, hides, copra, dried egg, cheese, guano, bone meal, dried figs, and palm nut kernels. Although refrigeration has reduced the impact of the beetle on meats, they are a significant destructive pest of dried and salt fish including herring. It was well documented as a threat to agriculture by 1925. ''Necrobia rufipes'' has been recorded in Egyptian mummies and were once ...

Forensic Entomology
Forensic entomology is a branch of applied entomology that uses insects and other arthropods as a basis for legal evidence. Insects may be found on cadavers or elsewhere around crime scenes in the interest of forensic science. Forensic entomology is also used in cases of neglect and abuse of a property, as well as subjects of a toxicology analysis to detect drugs and incidents of food contamination. Therefore, forensic entomology is divided into three subfields: medico-legal/medico-criminal entomology, urban, and stored-product. The field revolves around studying the types of insects commonly found in and on the place of interest (such as cadavers), their life cycles, their presence in different environments, and how insect assemblages change with the progression of decomposition (the process of "succession"). Insect assemblages can help approximate a body's primary location, as some insects are unique to specific areas. In medico-criminal cases, the primary goal is ofte ...

Beetles Described In 1775
Beetles are insects that form the order Coleoptera (), in the superorder Holometabola. 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 arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in dipterans (flies) and hymenopterans (wasps). 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 ...
