Cinnabar Moth
The cinnabar moth (''Tyria jacobaeae'') is a brightly coloured arctiid moth found as a native species in Europe and western and central Asia then east across the Palearctic to Siberia to China. It has been introduced into New Zealand, Australia and North America to control ragwort, on which its larvae feed. The moth is named after the red mineral cinnabar because of the red patches on its predominantly black wings. The species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. Cinnabar moths are about long and have a wingspan of . Cinnabar moths are day-flying insects with distinctive pinkish-red and black wings. There is little variation in patterning, although on rare occasions the red markings may be replaced with yellow, or the forewing is entirely red with a black border, or the wings are completely black. Like many other brightly coloured moths, it is unpalatable; the larvae use members of the genus ''Senecio'' as food plants. Many mem ...

Oxfordshire
Oxfordshire is a ceremonial and non-metropolitan county in the north west of South East England. It is a mainly rural county, with its largest settlement being the city of Oxford. The county is a centre of research and development, primarily due to the work of the University of Oxford and several notable science parks. These include the Harwell Science and Innovation Campus and Milton Park, both situated around the towns of Didcot and Abingdon-on-Thames. It is a landlocked county, bordered by six counties: Berkshire to the south, Buckinghamshire to the east, Wiltshire to the south west, Gloucestershire to the west, Warwickshire to the north west, and Northamptonshire to the north east. Oxfordshire is locally governed by Oxfordshire County Council, together with local councils of its five non-metropolitan districts: City of Oxford, Cherwell, South Oxfordshire, Vale of White Horse, and West Oxfordshire. Present-day Oxfordshire spanning the area south of the Thames was h ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids

Moths Described In 1758
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establish ...

Callimorphina
The Callimorphina are a subtribe of woolly bear moths in the family Erebidae. The subtribe was described by Francis Walker in 1865. Many of these moths are easily confused with butterflies, being quite brightly colored and somewhat diurnal. Their antennae are not thickened into "clubs", which is a typical characteristic of butterflies. Taxonomy The subtribe was previously classified as a tribe of the former family Arctiidae. Genera This list of genera in the subtribe were outlined by Michelle A. DaCosta and Susan J.

British Entomology
''British Entomology'' is a classic work of entomology by John Curtis, FLS. It is subtitled ''Being Illustrations and Descriptions of the Genera of Insects found in Great Britain and Ireland: Containing Coloured Figures from Nature of the Most Rare and Beautiful Species, and in Many Instances of the Plants Upon Which they are Found''. The work comprises 770 hand-coloured, copper-plate engravings, each 8 by inches (20×14 cm), together with two or more pages of text. The work was issued in monthly parts over 16 years, each part comprising three or more (usually four) plates. Plates were initially printed on James Whatman's Turkey Mill paper and then (circa 1832) on Rye Mill paper. It was a masterpiece of the engraver's and colourist's art, described by the eminent French naturalist Georges Cuvier as the "paragon of perfection". Close examination of a proof set of plates (see below) reveals an obsessive attention to detail. The shading of the foliage is typically achie ...

John Curtis (entomologist)
John Curtis (3 September 1791 – 6 October 1862) was an English entomologist and illustrator. Biography Curtis was born in Norwich to Frances and Charles Morgan Curtis. Charles Morgan died before his son had reached the age of 4 years. His mother, Frances, had a passion for flowers and was a professional flower grower. She encouraged her son to study natural history with a young local naturalist, Richard Walker (1791–1870). At the age of 16 John became an apprentice at a local lawyer's office in Norwich but devoted his spare time to studying and drawing insects and, with insect collecting becoming a growing craze, he found he could make a living selling the specimens he found. At this time he became a friend of Simon Wilkin (1790–1862) a wealthy landowner in Norfolk, eventually leaving his job to live with Wilkin at Cossey Hall where the extensive natural history library and specimen collection afforded him the opportunity to study his emerging over-riding passion, entomo ...

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ...

Pupa
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Longitarsus Jacobaeae
''Longitarsus jacobaeae'' is a species of flea beetle known as the tansy ragwort flea beetle. It is used as an agent of biological pest control against the nectar-rich noxious weed known as ragwort (''Senecio jacobaea'' reclassified as ''Jacobaea vulgaris''). The adult beetle is light golden brown in color and between and long. The female is larger than the male, especially when gravid. The beetle has enlarged femurs for its main locomotion method of hopping. The female lays eggs on or near the ragwort, its host plant. The larva emerges in about two weeks and burrows into the ground to feed on the roots. The larvae and adults are dually responsible for damage to the plant. The adult defoliates plants which are often already weakened by larval damage at the roots. This two-pronged attack is quite successful in preventing ragwort growth and development. The beetles have prevented entire populations of ragwort from reaching flowering stage at several monitored sites. The beetle i ...

Biocontrol
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ...

Formica Polyctena
''Formica polyctena'' is a species of European red wood ant in the genus ''Formica'' and large family Formicidae. The species was first described by Arnold Förster in 1850. The latin species name ''polyctena'' is from Greek and literally means 'many cattle', referring to the species' habit of farming aphids for honeydew food. It is found in many European countries. It is a eusocial species, that has a distinct caste system of sterile workers and a very small reproductive caste. The ants have a genetic based cue that allow them to identify which other ants are members of their nest and which are foreign individuals. When facing these types of foreign invaders the ''F. polyctena'' has a system to activate an alarm. It can release pheromones which can trigger an alarm response in other nearby ants. It is found in Austria, Belgium, Bulgaria, Czech Republic, Estonia, Finland, France, Germany, Hungary, Italy, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, Poland, Romania, ...
