Nyctemera annulata
''Nyctemera annulata'', the magpie moth, is a moth of the family Erebidae. The species was first described by Jean Baptiste Boisduval in 1832. It is endemic to New Zealand and found in all parts of the country. Description The magpie moth's "woolly bear" caterpillars are around 35–38 mm when fully grown and predominantly black with lines of red down its sides and back, blue spots and tufts of hair on each segment. Its liking for the introduced ragwort causes its caterpillars to be sometimes misidentified as those of the cinnabar moth which was introduced as a biological control for ragwort. By contrast cinnabar caterpillars have smooth bodies with alternating yellow and black rings. The adult moth has black wings with white markings on both the forewings and hindwings. The forewings have two white spots that are more elongated while the hindwing only has a single spot near to the centre; the wingspan is 35–45 mm.Landcare Research.

Jean Baptiste Boisduval
Jean Baptiste Alphonse Déchauffour de Boisduval (24 June 1799 – 30 December 1879) was a French lepidopterist, botanist, and physician. He was one of the most celebrated lepidopterists of France, and was the co-founder of the Société entomologique de France. While best known abroad for his work in entomology, he started his career in botany, collecting a great number of French plant specimens and writing broadly on the topic throughout his career, including the textbook ''Flores française'' in 1828. Early in his career, he was interested in Coleoptera and allied himself with both Jean Théodore Lacordaire and Pierre André Latreille. He was the curator of the Pierre Françoise Marie Auguste Dejean collection in Paris and described many species of beetles, as well as butterflies and moths, resulting from the voyages of the ''Astrolabe'', the expedition ship of Jean-François de Galaup, comte de La Pérouse and the '' Coquille'', that of Louis Isidore Duperrey. He left Paris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pyrrolizidine Alkaloid
Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine. Pyrrolizidine alkaloids are produced by plants as a defense mechanism against insect herbivores. More than 660 PAs and PA N-oxides have been identified in over 6,000 plants, and about half of them exhibit hepatotoxicity. They are found frequently in plants in the Boraginaceae, Asteraceae, Orchidaceae and Fabaceae families; less frequently in the Convolvulaceae and Poaceae, and in at least one species in the Lamiaceae. It has been estimated that 3% of the world’s flowering plants contain pyrrolizidine alkaloids. Honey can contain pyrrolizidine alkaloids, as can grains, milk, offal and eggs. To date (2011), there is no international regulation of PAs in food, unlike those for herbs and medicines. Unsaturated pyrrolizidine alkaloids are hepatotoxic, that is, damaging to the liver. PAs also cause hepatic veno-occlusive disea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Senecio Vulgaris
''Senecio vulgaris'', often known by the common names groundsel and old-man-in-the-spring, is a flowering plant in the family Asteraceae. It is an annual herb, native to Europe and widely naturalised as a ruderal species in suitable disturbed habitats worldwide. Description ''Senecio vulgaris'' is an erect herbaceous annual growing up to 16 inches (45 cm) tall. The inflorescences usually lack ray florets, the yellow disc florets mostly hidden by the bracts giving the flowers an inconspicuous appearance. ''Senecio vulgaris'' is very similar to ''Senecio viscosus'' but ''S. vulgaris'' does not have the glandular hairs and ray florets found in ''S. viscosus''. Leaves and stems Upper leaves of ''Senecio vulgaris'' are sessile, lacking their own stem ( petiole), alternating in direction along the length of the plant, two rounded lobes at the base of the stem ( auriculate) and sub-clasping above. Leaves are pinnately lobed and + long and wide, smaller towards the top of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacobaea Vulgaris
''Jacobaea vulgaris'', syn. ''Senecio jacobaea'', is a very common wild flower in the family Asteraceae that is native to northern Eurasia, usually in dry, open places, and has also been widely distributed as a weed elsewhere. Common names include ragwort, common ragwort, smegplant, stinking willie, tansy ragwort, benweed, James, son of Zebedee, St. James-wort, stinking nanny/ninny/willy, staggerwort, dog standard, cankerwort, stammerwort. In the western United States it is generally known as tansy ragwort, or tansy, though its resemblance to the true tansy is superficial. In some countries it is an invasive species and regarded as a noxious weed. In the UK, where it is native, it is often unwanted because of its toxic effect for cattle and horses, but it is also valued for its nectar production which feeds insect pollinators and its ecological importance is thus considered significant.

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moth Eggs On Ragwort 01
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.

Senecio
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
